What to do if you find a ‘lost’ baby animal
Most baby animals that appear to be lost are not; the parent is often nearby. In most cases, humans should let the animal be and leave so the parent will return. There are some exceptions. Here is a guide.
When in doubt, call a rehabilitator. Your local animal shelter can help you find one, or check the Web site of the National Wildlife Rehabilitators Association, http://www.nwrawildlife.org.
BABY RABBIT
Leave it alone if:
• It’s at least as big as a tennis ball and eating grass.
• It’s in a nest and the mother is caring for it. Check by placing a couple of light twigs across the nest and coming back the next day to see if they’ve been disturbed.
Call a rehabilitator if:
• You’ve checked as above and the nest is abandoned.
• The nest has been destroyed, such as by a dog.
BABY SQUIRREL
Leave it alone if:
• The mother is attending to it. Baby squirrels can fall from trees and be uninjured.
Call a rehabilitator if:
• You saw it attacked by another animal.
• It is following people around.
BABY BIRD
Leave it alone if:
• It’s mostly covered with feathers.
• You see parents caring for it.
• It’s hard to catch; if it can get away from you it’s probably healthy.
Call a rehabilitator if:
• It is injured or was attacked by a cat.
• It is sitting in the open asleep.
• If you see no parents taking care of it after going away and giving them a chance to return.
BABY DEER
Leave it alone if:
• It is lying quietly and is not being bothered by flies. The mother may have left it alone while she grazes.
Call a rehabilitator if:
• The baby is not moving to get flies off it; it may be ill or injured.
• You know the mother is dead - such as a fawn found beside a dead adult.
NOTE: Do not attempt to approach a deer over about 15 pounds; both you and the deer may be injured. Deer can kill an adult human! In all cases, if an animal is obviously injured, with a broken limb or bleeding, call a rehabilitator.

| The best way to control flea problems
is to prevent them from happening in the first place. Fortunately,
developments
in veterinary parasite control in recent years have made
the twofold goal of eliminating fleas on pets and preventing
further infestations much easier to achieve. |
Fleas are small, wingless,
blood feeding insects. Once on their hosts, fleas feed
daily.
The common household flea does not usually
transmit diseases to pets and people. They generally cause
a lot of itching and scratching. They may also cause some
discomfort due to possible allergic flea bite dermatitis. Did you know a female flea can produce up to 600 offspring
per month! The life span of the average flea is one year.
The flea’s main method of attack is to jump on their
prey – a flea can jump a distance equal to 150 times
their size.
Ticks, those other dreaded bloodsuckers, pose a greater
risk, annually giving pets and thousands of people illnesses
such as Lyme disease. Their average life span is usually
two years.
Unlike the flea, the tick is incapable of jumping or flying
to its prey. The tick uses its carbon monoxide sensing
ability of warm-blooded animals to detect the presence
of its prey. Once attached to your Golden, a female tick
can feast upon your dog for up to seven days!!
Lyme disease is generally caused by the Deer Tick, while
Rocky Mountain Spotted Fever is usually a result of a bite
from the American Dog Tick.
Modern science has produced a number of products which
can help your pet should it happen to suffer from fleas
and ticks. You and your veterinarian should choose which
product to use wisely, as products vary in their effectiveness.
For example, Advantage does not treat ticks – it
is only effective with fleas.
All products have advantages and disadvantages and may
or may not be safe to use with other products. The over-the-counter
powders, sprays and collars which contain pyrethrin, are
moderately effective. However, the best flea products are
obtainable only with a prescription. Consider these commonly
prescribed treatments:

Heartworm |
|
| Heartworm disease is a preventable, but serious
and potentially fatal, parasitic disease that primarily affects
dogs, cats and ferrets. It also infects wild animals such
as foxes, wolves, coyotes, and California Sea Lions. There
are documented human infections, but they are thought to
be rare and do not result in clinical disease. |
How is heartworm disease transmitted and what does it
cause?
Heartworms are transmitted from animal to animal by mosquitoes.
When an animal is bitten by an infected mosquito, young
heartworms (called microfilariae) are transmitted to that
animal. In about two weeks, the microfilaria develop into
larvae. The larvae, as they mature, move through the animal's
body and eventually enter the heart and blood vessels.
Over the next several months, the growing heartworms reach
adult size (female worms can reach up to 14 inches in length)
and reproduce. In time, the worms cause injury to the pulmonary
vessels and heart. This can lead to severe lung disease,
heart disease and damage to other organs. Heartworms may
survive for 5 to 7 years in dogs.
Where is heartworm disease found?
Geographically, heartworms are a potential threat in every
state except Alaska, as well as in many other countries
around the world. All dogs, regardless of age, sex, or
living environment, are susceptible to heartworm infection.
Indoor, as well as outdoor, cats are also at risk for
the disease. If you plan to travel with your dog or cat
to a different part of the country, ask your veterinarian
about the risk of heartworm disease in the area where
you are going to relocate or visit.
How can I tell if my pet has heartworm disease?
Dogs: If your dog has been recently or mildly infected
with heartworms, it may initially show no signs of disease.
However, as the disease progresses, your dog may cough,
become lethargic, lose its appetite or have difficulty
breathing. You may notice that your dog seems to tire
rapidly after only moderate exercise.
Your veterinarian will test your dog's blood for the presence
of adult heartworms. Further tests, such as chest x-rays
and an echocardiogram, may be necessary to confirm the
diagnosis and to help determine the severity of the infection.
Cats:
Signs of possible heartworm infection in cats include
coughing, respiratory distress, and vomiting. (In rare
cases, a cat may suddenly die from heartworms.)
The diagnosis of a heartworm-infected cat is more difficult
than with dogs. A series of different kinds of tests may
be needed to help determine the likelihood of heartworm
infection being the cause of your cat's illness and, even
then, the results may not be conclusive.
How can my pet be treated?
Dogs: As with most medical problems, the best defense is
prevention. However, if your dog is infected with heartworms,
there is an FDA-approved treatment available. Although
there is some risk involved in treating a dog for heartworms,
serious complications are rare among dogs that are otherwise
in good health and if the disease is detected early.
The goal of heartworm treatment is to kill the adult worms
that are present in your dog's body. While your dog is
hospitalized and for a period of time afterwards, it will
require complete rest and may need additional medications
to help limit inflammatory reaction as the worms die and
are absorbed by the body.
Cats: There is currently no effective and safe treatment
for heartworm infection in cats. If your cat is diagnosed
with heartworms, your veterinarian may recommend medications
to limit the inflammatory response and the resulting heartworm
disease.
Can heartworms be surgically removed?
Some veterinarians are equipped for surgical removal of
heartworms from dogs and/or cats. This procedure, however,
is typically reserved for severe cases.
Can heartworm disease be prevented?
Heartworm disease is almost 100% preventable in dogs and
cats. There are several FDA-approved heartworm preventives
available in a variety of formulations. Your veterinarian
can recommend the best method of prevention based upon
your pet's risk factors and lifestyle.
A blood test for existing heartworm infection is recommended
before beginning a prevention program to confirm that your
pet is not already infected with the disease. In addition,
annual re-testing is recommended to check your pet's status
and ensure that the appropriate medication is being prescribed.

Spaying or Neutering |
|
| Spaying and /or neutering increases your pet's
chances of a longer, healthier life. Spaying a female before
her
first
heat cycle
greatly
reduces her chances of having breast cancer and eliminates
any threats of uterine cancer or infection, which are common
in unaltered females. Neutering a male prevents testicular
tumors and may prevent prostate problems. |
It also decreases the chance of any perianal
tumors or hernias, which are common in older unaltered
males.
Neutered cats are
less likely to roam and therefore less likely
to get
abcesses which are caused by cat bites or become infected
with diseases.
An altered dog or cat makes a better pet. No family
needs to deal with an unwanted pregnancy. Spaying prevents
unwanted babies. Males neutered early on are usually less
aggressive towards males and less distracted by females
in heat, which they can smell miles away! Males that are
altered are less likely to mark inside or outside your
home.
Spaying results in a cleaner female dog and home. Female
dogs pass usually pass body fluid for 10 days, twice a
year, as part of their heat cycle. Constant care will need
to be taken to keep carpets stain free while your female
is in heat.
You are helping to alleviate the dog and cat overpopulation
problem. Every year millions of cats and dogs are euthanized
at shelters and clinics all over the country due to the
shortage of homes. Pet behavioral problems are the number
one reason pets are given up. Many of the homeless animals
though are results of unplanned breeding by free-roaming
and unaltered animals. The more pets are altered the less
cats and dogs have to be killed!
Effects of neutering /spaying on behavior
-Effect on sexual behavior: Sexual behavior usually disappears
after altering you cat or dog. Animals that have experienced
sexual behavior prior to sterilization however may persist
in their sexual behavior because it becomes a learned behavior.
Mounting for example is not a sexual behavior for altered
pets, it's a sign of dominance within the pack.
-Effect on aggression: It's been shown that aggressive
acts appear more often in unaltered males and females then
in sterilized pets. Fighting is very likely within a group
of unaltered males but should cease after being they're
neutered. If your pet is not a pure-bred then you should
sterilize it to avoid aggression related to sexual hormones.
-Effect on general temperament: Contrary to popular believe
spaying or neutering your pet does not effect your pets
temperament or intelligence. You do not deprive your pet
of any essential experiences by being responsible and altering
your pet. Females are highly unlikely to improve in temperament
after having a litter and males do not benefit from sexual
activity either.
-Effect on inappropriate elimination: Altering
your pet early may help in ending improper elimination
in your home,
which is done to mark it's territory.

Dental Health
 Periodontal disease is
the most common oral disease in dogs and cats. Indeed, It’s
also the most overlooked disease.
Sometimes
pets suffer with severe periodontal disease before anything
is done about it. |
Unfortunately, if left untreated, periodontal disease
only gets worse, until eventually it undermines the general
health of you pet. The mouth is said to be the most
biologically active area of the body, from
a diseased mouth can affect various organs of the body
and the nervous system. Investigators
believe that certain diseases of feline old age, such as
diseases of the kidneys and possibly some diseases of the
heart and liver, can be attributed to untreated oral disease.
And human medicine has taught us that healthy mouths can
help us live longer. There’s
no reason to believe the same isn’t also true for
animals.
Owners, however, shouldn’t think of mouth care as
something to pay attention to only in their pet’s
later years. Studies show that most pets over the age of
2 years show signs of oral disease to some degree.
Whiff of a Problem
Since cats and dogs are not noted for their cooperation
when it comes to mouth inspections, owners can easily miss
the
early stages of oral disease in their feline companions.
There are, however, several signs that, although not exclusive
to oral disease, should alert you to the need for a thorough
and detailed veterinary examination of your pet’s
mouth. Bad breath is certainly one "red flag." Other
indications are when your pet rejects hard, crunchy food;
avoids certain parts of its mouth when eating; paws at
its mouth; or begins to drool. We recommend regular veterinary
dental checkups as part of your pet’s wellness program,
which should also include routine physical checkups and
booster "shots." Although oral disease is very
common, the good news is that if it is treated early enough
- with home brushing and professional prophylactic cleaning
- you and your veterinarian can do much to reverse its
effects.
Periodontal Disease
Periodontal disease involves the tissue and structures
that support the teeth - the gum (gingiva) and the bone
(alveolar bone). The disease ranges in severity from inflammation
of the gum (gingivitis) to ulceration of the gum and resulting
loss of supporting bone structure (periodontitis). Advanced
periodontitis leads to the loosening and eventual loss
of teeth. Treatment of periodontal
disease is the most important aspect of veterinary dentistry.
Gingivitis
Gingivitis, the early stage of periodontal disease, is
relatively easy to spot. It appears as a red line of inflammation
where the gum meets the tooth. This inflammation of the
gingival (gum) tissue is caused by deposits of plaque that
build up on the surface of the tooth beneath the gum tissue.
Plaque, a combination of bacteria, food particles, and
saliva, is constantly forming and hardening on the surface
of the tooth. The high concentration of bacteria (80 percent)
in plaque makes it an effective pathological (disease-causing)
agent.
As plaque deposits build up, they harden into calculus
(tartar) and enlarge the pocket (sulcus) between the tooth
and the gum. This enlarged sulcus traps debris and creates
a fertile environment for bacterial growth. Saliva, which
normally washes out the sulcus, can no longer do its job
effectively and clear out the sulcus. Multiplying bacteria
invade the gingival tissue. The gums become swollen and
are liable to bleed when probed. Fortunately, at this early
stage, the teeth have not lost their supporting bone structure.
So if gingivitis is detected early and treated promptly,
its effects are reversible.
When gingivitis is apparent, we are now performing laser
surgery to help reduce the gingivitis of the mouth. This
procedure is performed during the dental prophylaxes.
Periodontitis
Periodontitis, the advanced stage of periodontal disease,
occurs when bacteria, their waste products, and other toxins
cause the gums to ulcerate. Over time, an increasing buildup
of calculus causes ever-deepening pockets to form around
the teeth. Eventually, the alveolar bone begins to erode.
Finally, erosion of the gingival and alveolar bone advances
to such a degree that the teeth no longer have anything
to support them. The become loose and fall out. (These
lost teeth are almost always healthy teeth.) Unfortunately,
periodontitis is not reversible. But if treated early enough,
it can be controlled.
What You Can Do
Plaque forms every 6 to 8 hours. And merely rinsing your
pet’s mouth will not remove the buildup. To effectively
remove plaque, you need to brush your cat’s teeth
- preferably every day. While brushing takes discipline,
it doesn’t take a lot of time - no more than 15 to
30 seconds. Admittedly, most cats do not clamor to have
their teeth brushed, but most will tolerate it if you set
up a routine, stick to it, treat brushing like a game,
and always remember to reward your pet afterward.
What Your Vet Can Do
Your veterinarian is also your pet’s dentist.
Your veterinarian should examine your pet’s gums
and teeth at least once a year - more often if your pet
needs it. (Some dogs and cats build up plaque faster than
others.)
To catch problems early, it is essential that the owner
and veterinarian work as a team. An observant owner may
notice subtle changes in a pet’s mouth or behavior
that he or she can bring to the veterinarian’s attention
during a routine checkup. Alerted to potential trouble
spots, the vet can the schedule time for a detailed oral
examination.
Prevention
Prevention is the key to helping pets maintain good oral
health. The American Veterinary Dental Society recommends
that pet owners follow three important steps:
Visit Your Veterinarian
Just as dental visits are the cornerstone of a human
dental program, visiting a veterinarian is the key to
ensuring
the health of your pet's teeth. A veterinarian will conduct
a thorough physical examination of your pet as part of
the dental evaluation.
Start a dental care routine at home
Removing plaque regularly from your pet's teeth should
be part of your pet's home dental care routine. Ask your
veterinarian about the procedure for brushing your pet's
teeth. Dog owners also may feed specially formulated
dietary foods that help reduce the accumulation of plaque
and tartar from teeth when the pet eats. Your veterinarian
can offer more information on dietary options.
Get Regular Veterinary Dental Checkups
The family veterinarian needs to monitor the progress of
your pet's preventive dental care routine much the same
way a dentist monitors your teeth. Regular dental check-ups
are essential.
Once a pet's teeth display the warning signs — bad
breath, a yellow brown crust of tartar around the gumline,
pain or bleeding when the pet eats or when you touch its
gums — gum disease may already be present.

Pet Wellness |
|
| For millions of health-conscious Americans,
the annual checkup has become a routine practice. Like people,
dogs and cats can benefit from routine wellness exams too.
But with one important difference - pets age faster than
people. |
On average, most dogs and cats reach adulthood by age two,
says Dr. Marty Becker, a veterinarian and consumer spokesperson
for National Pet Wellness Month, an educational initiative
sponsored by the American Veterinary Medical Association
and Arcanum Veterinary Service. By age four, many pets
are entering middle age. And by age seven, most dogs,
particularly larger breeds, are entering their senior
years.
Because dogs and cats age seven times faster, on average,
than people, significant health changes can occur in a
short amount of time. And, the risks of cancer, diabetes,
obesity, arthritis, heart disease, metabolic problems and
other serious conditions all increase with age.
Many pet owners are not aware that taking a dog or cat
to the veterinarian once a year is the same as a person
seeing their doctor or dentist once every seven years.
It is recommended that pets have a wellness exam every
six months so
that veterinarians have the opportunity
to detect, treat or, ideally, prevent problems before they
become life-threatening.
"Prevention is the real goal of twice-a-year wellness
exams," says Dr. Becker. "When veterinarians
see a pet on a regular basis, they can help pets avoid
some preventable illnesses and diseases. Plus, a pet will
never have to suffer from pain that could be treated or
prevented by the veterinarian."
Pet wellness exams include screenings for a variety of
potential diseases. These screenings are usually accompanied
by an individualized risk assessment of your pet's environment
- where you live, emerging disease risks in your community,
your pet's interaction with other pets and wildlife, travel
plans, and other lifestyle considerations.
Pet wellness exams also help your veterinarian determine
a proper prevention program, including a vaccination schedule
tailored specifically for your pet. By using personalized
pet health protocols, veterinarians can pinpoint specific
preventive health care needs for your pet.
A pet owner's best source for wellness exam and preventive
health care information is their personal veterinarian. "Only
your veterinarian knows your pet's medical history, current
health status, and potential risks your pet faces," says
Dr. Becker.

ZOONOTIC PARASITES |
|
| Whether you own a fish, amphibian, reptile,
bird or mammal you can promote your pet's health along with
your own by being alert to possible problems. Even if you
don't own a pet or come into contact with one, you should
be aware that many animals, vertebrates and invertebrates
(e.g., snails), living or dead, could have an effect on your
health by way of zoonotic diseases. |
Zoonotic diseases are diseases of animals that can be
transmitted to humans. Some of the best known zoonotic
diseases include the plague—fleas bite infected rats
then pass the disease on when the flea bites a human—rabies,
and Lyme disease.
Sources of Zoonotic Diseases
As long as you're in the immediate environment of animals
or untreated animal products, you're at risk of contracting
a disease or infection that can be traced to them. Sometimes
toxins or poisons linked to animals are transmitted to
us through the environment.
A wide range of health problems may be linked to animals.
Some common sources of disease-causing organisms include
contaminated meat or milk food such as fruits, vegetables
and other
produce such
as mushrooms that are contaminated with animal waste
or product
direct contact with a living animal that causes you an
injury or transfers a bacterium, virus, fungus or parasite
to you
contaminated materials such as soil and water that have
come in contact with animals, animal by-products or animal
waste.
How Humans Contract Zoonotic Diseases
The nose, ears, eyes and mouth serve as easy points of
entry for viruses, bacteria and parasites. This means
that air, water, food, soil and direct contact with an
animal
play a part in assisting disease-causing organisms or
infectious agents to enter your body. Of course, cuts
and scrapes
in the skin can provide entry points as well.
The most common way humans are infected with a zoonotic
disease is through indirect transmission. Pets are most
likely to transmit an external parasite such as a flea
or tick, which is infected with the virus. Once the external
parasite bites the human, the disease is transmitted. Viruses
and bacteria are also transmitted through nasal droplets
and feces. Feces may also contain other internal parasites
such as roundworms.
Sometimes a disease-causing agent in an animal is disease-causing
in humans as well. Diseased cattle and swine have had to
be destroyed because eating the meat, even when cooked,
would have meant that the disease-causing agent would infect
white blood cells in humans. Sheep, mink, mule, deer and
elk have also been implicated in the transfer of a disease-causing
agent. Consumption of deer and elk meat has been implicated
in a number of cases of chronic wasting disease, a member
of the family that also includes bovine spongiform encephalopathy
(a.k.a. mad cow disease).
What is important to remember, however, is that an infected
animal may exhibit no symptoms of having a disease.
People at Risk of Zoonotic Diseases
Everyone is at risk, but these groups of people are much
more susceptible to contracting a zoonotic disease:
infants and small children — their immune systems
are not yet fully developed.
pregnant women — their immune systems may be weakened.
the elderly — they may have impaired immune systems.
Preventing Zoonotic Diseases
There are no guarantees that an individual will or will
not contract a disease, but avoiding certain behaviors
and practices helps minimize the risk. Of course you'll
need to keep up the "pro-active" behaviors such
as washing hands with soap and water.
Many common practices can help minimize the transfer of
harmful bacteria, viruses and parasites to humans and human
food. These include:
1. - Have
your pet tested throughly from your Vet
2.
- Feed your pets commercial or home-cooked food
3. - careful disposal of all pet waste
4. - preventing cross contamination from raw to cooked
food through surfaces such as cutting boards, knives, utensils
and human hands
thoroughly washing all vegetables
cooking meat thoroughly.
Ascarids (Toxocara canis, T. cati) and hookworms (Ancylostoma
spp.) are common intestinal parasites of dogs and cats
(referred to here as pets). Not only can ascarids and hookworms
cause disease in their respective hosts, they are also
well-known causes of larva migrans syndromes in humans,
especially children. While ascarids and hookworms are most
commonly diagnosed in puppies and kittens, infections can
occur in dogs and cats of all ages. Dogs can also become
infected with Baylisascaris procyonis, the common raccoon
ascarid, which can cause serious disease in other animals
and humans.
Ascarids — Because
of the occurrence of both transplacental and transmammary
transmission of T. canis, puppies are
usually born with or acquire ascarid infections early
in life. Kittens do not become infected in utero, but
like puppies, can acquire ascarids (T. cati) through
the queen’s milk. The tissue-migrating and early
intestinal stages of these worms may cause severe, sometimes
life-threatening, disease in the first few weeks of life.
Patent intestinal infections can develop within the first
2½ - 3 weeks of life. Left untreated, this can
lead to widespread contamination of the environment with
infective eggs.
Hookworms — Both
puppies and kittens acquire hookworm infections (A. caninum,
A. braziliense, and A. tubaeforme)
through ingestion of or skin penetration by infective
larvae, or from infective larvae passed in their dam’s
milk (A. caninum). Hookworms suck large amounts of blood
from their hosts and while infected animals may look
healthy in the first week of life, they can develop a
rapidly severe, often fatal, anemia. Patent intestinal
infections can occur as early as 2- (dogs) to 3- (cats)
weeks of age, leading to environmental contamination
with infective larvae.
The prevalence of these infections varies with climatic
conditions; however, they are present in all parts of
the United States and must be viewed as a potential public
health hazard.
Zoonotic Transmission and Human Disease
The growing popularity of dogs and cats in the United
States, together with high rates of ascarid and hookworm
infections, has resulted in widespread contamination
of the soil with infective eggs and larvae. Epidemiologic
studies have implicated the presence of dogs, particularly
puppies, in a household, and pica (dirt eating) as
the principal risk factors for human disease. Children’s
play habits and their attraction to pets put them at
higher risk for infection than adults.
Humans become infected with ascarids (Toxocara spp.,
Baylisascaris spp.) through ingestion of infective eggs
in the environment. When a human ingests infective eggs,
the eggs hatch and release larvae that can migrate anywhere
in the body, a condition known as visceral larva migrans.
The signs and symptoms seen in humans are determined
by the tissues or organs damaged during larval migration.
Organs commonly affected are the eye, brain, liver, and
lung, where infections can cause permanent visual, neurologic,
or other tissue damage. The common dog ascarid, T. canis,
has long been recognized as a cause of larva migrans
syndromes in children. The cat ascarid, T. cati, can
also cause disease in humans, although for reasons partly
related to the defecation habits of cats, it does so
less frequently. The raccoon ascarid, B. procyonis, is
increasingly being recognized as a cause of human disease.
Humans can become infected with hookworms through ingestion
of infective larvae or through direct penetration of
the skin.7 When infective larvae penetrate the skin,
they undergo a prolonged migration that causes a condition
known as cutaneous larva migrans. These larval migrations
are characterized by the appearance of progressive, intensely
pruritic, linear eruptive lesions, which are usually
more extensive with A. braziliense infections. A. caninum
larvae may also penetrate into deeper tissues and induce
symptoms of visceral larva migrans, or migrate to the
intestine and induce an eosinophilic enteritis.
The Public Health Problem
Larva migrans syndromes are not reportable in the United
States, so the actual number of human cases is unknown.
However, many human cases continue to be diagnosed
and a recent national survey of shelters revealed that
almost 36% of dogs nationwide, and 52% of dogs from
southeastern states harbored helminths capable of causing
human disease. Every year at least 3,000-4,000 serum
specimens from patients with presumptive diagnoses
of toxocariasis are sent to the Centers for Disease
Control and Prevention (CDC), state public health laboratories,
or private laboratories for serodiagnostic confirmation.
Zoonotic hookworm infections are more geographically
restricted than toxocariasis, with most cutaneous larva
migrans and other hookworm-associated syndromes diagnosed
in southeastern and Gulf Coast states. Persons likely
to come in contact with larvae-contaminated soil include
electricians, plumbers, and other workers who crawl
beneath raised buildings, sunbathers who recline on
larvae-contaminated sand, — as well as children
who play in contaminated areas. While most hookworm
infections are self-limiting, massive infections can
lead to infection of deeper tissues.
Veterinarians Can Help Prevent Human Disease
Most cases of human ascarid and hookworm infections can
be prevented by practicing good personal hygiene, eliminating
intestinal parasites from pets through regular deworming,
and making potentially contaminated environments, such
as unprotected sand boxes, off limits to children.
It is also important to clean up pet feces on a regular
basis to remove potentially infective eggs before they
become disseminated in the environment via rain, insects,
or the active migration of the larvae. Hookworm eggs
can develop into infective stage larvae in the soil
in as little as 5 days, and ascarid eggs within 2 weeks,
depending on temperature and humidity. To illustrate
the extent of environmental contamination that can
occur as the result of one infected puppy, a single
female ascarid can produce more than 100,000 eggs/day,
resulting in millions of potentially infective ascarid
eggs per day spread throughout the area the puppy is
allowed to roam.10 Once the eggs become infective,
they can remain infective in the environment for years.
Most pet owners do not know that their pets may carry
worms capable of infecting people. Therefore, practicing
veterinarians can provide an important public service
by recommending regular fecal examinations, providing
well-timed anthelmintic treatments, counseling clients
on potential public health hazards, and advising them
