Q1. What
are fleas?
Adult fleas are wingless insects, generally smaller than a sesame
seed, which feed on the blood of animals. Their proportionately
enlarged back pair of legs gives them an extraordinary jumping
ability. Hanging on to your pet's fur with their claws, their
needle-like mouth parts bite through the skin to suck up blood.
Q2. What is the Life Cycle
of Fleas?
Fleas spend most of their lifetime off the pet. They go through
a life cycle that includes egg and cocoon stages. While adult
fleas are relatively easy to kill with insecticides, the egg
and cocoon stages are very resistant.
The entire life cycle of the flea (from egg to larva, from
larva to cocoon, from cocoon to adult) can vary from 14 days
during warm, moist weather, to several weeks or months under
extremes of climatic conditions.
The adult flea must dine on your pet's blood to survive.
Fleas can jump from 16 to 36 inches. For their size, this
is like a human jumping over the Washington Monument!
" Successful flea control must be directed at both the
pet and the environment.
" Always coordinate treatments to break the life cycle
of the flea and to treat the environment and pet at the same
time.
" Consult our health care team to determine the best
product for your pet.
Q3. Are there medical
problems associated with fleas?
" Skin Infections: "Hot spots" are frequently
seen in animals with flea infestations. Hot spots can pop
up from intense scratching and licking. Hot spots can also
be found on non-allergic animals as the result of problems
unrelated to fleas.
" Tapeworms: Fleas are an essential link in the life
cycle of the tapeworm in the cat or dog. A good flea control
program should accompany the treatment of your pet for tapeworms.
The tapeworm is a segmented worm that is only occasionally
passed whole. Instead, you will usually only see a number
of individual white segments passed in the stool, around the
animal's anus, or on their bedding. These may have the appearance
of rice grains.
" Anemia: A pet heavily infested with fleas can lose
a significant portion of its circulating blood. This may lead
to decreased resistance to other disorders and cause your
pet to act lethargic.
Q4. What is flea allergy
dermatis?
Fleas can cause a condition known as allergic dermatitis.
Because some dogs and cats are allergic to flea saliva, a
single flea- bite causes the animal to chew and scratch the
area where the flea has bitten. This can cause redness, sores
and hair loss. One or two fleas on an allergic animal may
trigger the same response as a hundred flea- bites.
Some pets need medication to control the scratching and chewing
until a flea control program can be started. Animals with
severe allergic dermatitis may require intermittent use of
prescription medications coupled with flea prevention during
those periods when fleas are most active during hot, humid
months.
Remember, use of these medications is not a substitute for
a flea control program.
Q5. How can I protect my
pet from fleas?
In order to ensure the safety of your pet it is recommended
that you consult your veterinarian to determine which product
is best. Some retail products can be dangerous and may not
be sufficient for optimal protection. Your veterinarian will
ensure that your pet is in good health before prescribing
prevention and guide you on proper usage.
Q6. What is Heartworm Disease?
Canine Heartworm disease is a serious and potentially fatal
parasitic condition caused by a blood-borne parasite known
as Dirofilaria immitis. The worm is transmitted by mosquitoes,
matures and resides in the heart and can result in severe
damage to the heart and surrounding blood vessels of the dog.
If infection with heartworm is prolonged damage to the kidneys,
liver, joints and eyes can also occur.
Q7. How is Heartworm
transmitted?
Adult worms produce offspring called microfilariae, which
circulate in the bloodstream and are ingested by mosquitoes
when they feed from an infected animal. The microfilariae
undergo development in the mosquito and are then transmitted
to another dog or animal when that mosquito bites. Dogs are
considered the most common host for heartworm, however heartworm
may also infect more than thirty animal species (including
coyotes, foxes, wolves, domestic cats, ferrets) and even humans.
Q8. What dogs are
at risk for Heartworm?
Heartworm is a parasitic disease that can affect any dog regardless
of age, sex or habitat. If there is the potential for exposure
to heartworm then there is an inherent risk of infection.
Q9. What are the
symptoms of Heartworm disease?
Many dogs will show little or no sign of infection even after
the worms become adults. If symptoms were present they would
include difficulty breathing, a persistent cough, fatigue
or reluctance to exercise, listlessness, weight loss or a
rough hair coat. In more severe cases signs include liver
enlargement, temporary loss of consciousness due to poor blood
flow to the brain and excessive fluid in the abdomen.
Q10. Can Heartworm
be prevented?
Yes. There are a variety of options for preventing heartworm
infection, including monthly topical and monthly chewable
or flavoured tablets. Preventative medications are extremely
effective and when given properly, on a regular basis, can
completely prevent your pet from contracting heartworm.
A blood test will be taken prior to dispensing preventative
medications to ensure your pet is not heartworm positive.
Remember, year-round or seasonal heartworm protection is only
as good as your diligence in remembering to give your pet
the prescribed medication as directed by your veterinarian.
IS HEARTWORM PROTECTION COMPLIANCE
A MAJOR PROBLEM?
Several studies show that dog owners often forget to administer
their dog's monthly heartworm preventative as recommended.
Specifically, a North American survey of dog owners, conducted
in the summer of 2000 found that more than 80 percent had
failed to give their dogs the monthly heartworm preventative
on the due dates as directed. One third of dog owners surveyed
entirely missed a monthly dose, and 20 percent of those who
missed eventually stopped giving the preventative all together.
An earlier study by Merck Ag Vet, revealed that only 56.4
percent of heartworm medications are administered as recommended
by the veterinarian. MISSING A HEARTWORM DOSE CAN PUT DOGS
AT RISK FOR HEARTWORM DISEASE.
Q11. What are intestinal
parasites?
Intestinal parasites include many different types such as
round, hook and tapeworms. Some of these only infect pets
while others can be zoonotic meaning that they can be transmitted
to humans.
Q12. What are roundworms?
Roundworms are parasitic worms that are round in shape, live
in the dog's intestines and consume partially digested food.
Adult worms resemble spaghetti and may come out in the feces
or vomit of an infected dog. Transmission to dogs is through
eggs in the feces which contaminate soil that may be ingested.
These worms are also transmitted by eating a prey animal that
is infected (usually rodents) as well as to puppies from the
mother's milk or while in the uterus.
In dogs, roundworms cause diarrhea, vomiting and in extreme
cases, intestinal obstruction. It is important to note that
these worms are zoonotic and can infect humans by transmission
of the eggs. In humans, roundworms can cause a serious condition
known as visceral larval migrans. Most victims are children
who are infected when putting contaminated fingers into their
mouths. Once ingested, the roundworm egg develops into a larva
and tries to complete its lifecycle. The roundworm gets lost
in the human body, usually in the eye, dies and generates
an inflammatory reaction that can cause blindness. Proper
hand washing can prevent infection. Deworming of puppies if
infected and preventative medication will reduce environmental
contamination.
Q13. What are hookworms?
In dogs, hookworm infection occurs through ingestion or skin
penetration of hookworm larvae found in the stools or soil
contaminated by feces of an infected animal. Puppies can also
be infected in the uterus or by consuming their mother's milk
if she has a hookworm burden. The larvae then develop and
migrate to the intestines where they hook onto the intestinal
wall and feast on the host's blood.
These parasites are also zoonotic. The larvae of hookworms
can penetrate the skin and infect humans through contact with
soil or sand contaminated by feces of host dogs or cats. In
a human host, the hookworm larvae do not migrate to the intestines
and become blood-sucking adults as they do in pets. Instead,
they move around under the skin and eventually die causing
an inflammatory skin reaction known as cutaneous larval migrans,
or "creeping eruptions". It is important to keep
your pet free of hookworms with good hygiene, preventative
medication and regular veterinary check ups. Also, keep stray
dogs and cats out of sandboxes and gardening areas.
Q14. What are tapeworms?
Tapeworms are long flat worms that grow in segments. This
parasite is not zoonotic. One type of tapeworm is transmitted
through fleas while another type is transmitted to cats by
hunting and consuming mice or rats and to dogs by hunting
and consuming rabbits.
Many people who had thought their pet could not possibly have
fleas find out about the infestation this way. The tapeworm
segment breaks open releasing its eggs. A larval flea consumes
the egg along with the flea dirt that it normally eats. As
the larval flea matures, so does the baby tapeworm. When a
grooming dog or cat licks the flea and swallows it, the dead
flea is digested in the dog's stomach releasing the baby tapeworm.
The tapeworm is passed to its new home in the dog or cat's
small intestine where it attaches and lives its life.
This parasite rarely causes any problems in pets aside from
an itchy hind end. Consider that your pet has tapeworms if
segments are seen under its tail, around its anus, or on its
feces. Tapeworm segments generally look like a grain of rice,
although segments can be passed in small groups connected
to each other and look a little larger than a grain of rice.
Q15. How can I prevent
parasites in my pets and myself?
Children are more prone to contracting zoonotic parasites,
as they tend to kiss and play more readily with pets. Parasite
larvae are shed in the pet's feces and may contaminate soil
and sand. When children play in the contaminated areas and
place their fingers in their mouths this allows the eggs to
be ingested, causing infection. Be sure to pick up feces promptly
and avoid eating while playing with your pet. If a children's
sandbox is present it is recommended to cover it when not
in use. Frequent hand washing, as well as good general hygiene
for people and dogs, is recommended.
Routine check ups by your veterinarian - including a diagnostic
test for worms and heartworm - as well as a physical exam
along with medical prevention, will not only keep your dog
healthy but will reduce any risk to you and your family.
Q16. What is ringworm?
Ringworm is not actually a worm but a skin infection caused
by a fungus. This is another zoonotic disease that can be
transmitted from animals to humans.
The fungi feed upon the dead cells of skin and hair and in
people cause a classic round, red lesion with a ring of scale
around the edges and normal recovering skin in the center.
The fungi responsible are known as dermatophytes and a ringworm
infection is more correctly known as dermatophytosis. In animals,
ringworm frequently looks like a dry, grey, scaly patch but
can also mimic any other skin lesion and have any appearance.
Q17. How can my
pet get ringworm?
The spores of dermatophyte fungi are extremely hardy in the
environment; they can live for years. All it takes is skin
contact with a spore to cause infection. Infected animals
are continuously dropping spore-covered hairs as infected
hairs break off into the environment. Some animals are carriers,
who never show signs of skin irritation themselves but can
infect others readily.
Q18. Can humans
become infected by ringworm?
Yes, ringworm is contagious to people; however, some people
are at a greater risk than others. The fungus takes advantage
of skin belonging to those with a weaker immune system. This
puts young animals and children, elderly people and pets,
those who are HIV-positive, people on chemotherapy or taking
medication after transfusion or organ transplant and highly
stressed people and animals at a higher risk. In general,
if you do not already have ringworm at the time your pet is
diagnosed, you probably will not get it.
