How do I know if my pet has intestinal parasites?
When pets are infected with parasites, you may or may not see signs. Hopefully, the infection will have been treated or diagnosed (by regular stool checks) before they become ill.
Why not just test the stools and treat when the test shows parasites?
Testing stool samples for parasite eggs should be done routinely, every couple of months when your pet is young, and at least annually when they are an adult.
However, on some days the worms produce few eggs, or in many cases, the worms are too young to produce eggs. In these situations, we may not find evidence of infection microscopically. Stool samples, therefore, do not demonstrate the presence of parasites 100% of the time.
We do not always depend on a negative stool sample. We include many factors before making a conclusion.
Why treat for worms when the stool test was negative?
Routine treatments are required because the incidence of parasites is so high, and it poses a health risk both to pets and people.
It is actually good news when the stool sample is negative, because the worms present are young, who are not yet producing eggs. This means less risk for re-infection of your pet, less risk for your family, and less contamination of the environment.
Why bother checking stool samples at all?
Firstly, stool samples are performed to help assess the success of deworming treatments of confirmed cases.
Stool checks are also required routinely to check for the other parasites that are not treated by the standard deworming treatment (Giardia, Coccidia, Tapeworms, etc.), and to check for more unusual parasites (Physaloptera, Paragonimus, Alaria).
Skin parasites (Sarcoptes, Demodex mites) may show on stool samples after pets chew their itchy skin and swallow the microscopic mites. This is an unexpected but effective means of diagnosing skin mites.
What is the safe plan for treatment of worms?
Any deworming treatments done before you got your pet were just the beginning of the deworming program. There is a huge difference between receiving deworm treatment(s) and being free of worms.
Furthermore, medications used by breeders or humane societies are not as effective as the medications we use in the veterinary hospital. Products available over the counter at pet stores are not effective, have very limited treatment ranges, are often outdated, and often have significant toxicity concerns.
There is no room for error when dealing with the health of people and our pets.
Can worms pass to people?
Absolutely, yes. Diseases which pass from animals to humans are termed “zoonotic” diseases. Several common pet parasites can pass to people in a variety of stages. The symptoms can range from showing no signs to causing a variety of symptoms including:
- Skin irritation
- Diarrhea
- Development of internal cysts
- Seizures
- Blindness
Treating your pets’ intestinal parasites is extremely important for your entire family.
How do I keep my family safe?
We recommend cleaning up stools immediately, washing hands after handling puppies and kittens, and discouraging face licking, especially for children and people with compromised immune systems.
Ensure that you have a fresh stool sample checked microscopically at least annually, provide a sample for the follow-up test if worms were found on a previous sample, and make sure to follow all deworming protocols according to directions.
Make sure to cover sandboxes, which cats may use as a toilet. Be very careful if raccoons are around to wear gloves and wash hands well when working in the garden, and for children to wash before eating, and when coming indoors.
Pregnant (or possibly pregnant) women should not clean or change the cat litter, should wash hands well after gardening, and only eat well-cooked meat or fish.
