Fecal Exams

Signs Your Pet May Have Intestinal Parasites

Intestinal parasites are more common than most pet parents realize. Many infected pets show no symptoms, which is why regular fecal exams are an essential part of routine wellness care. When symptoms do appear, they may include:

Digestive issues such as diarrhea, loose stool, blood or mucus in stool, or vomiting (sometimes with visible worms).

Weight and appetite changes, such as weight loss despite normal eating, or a potbelly appearance, especially in puppies and kittens.

Visible worms appearing as rice-like segments near your pet's rear end or spaghetti-like strands in stool or vomit.

Behavioral signs include scooting, excessive licking around the rear end, or general restlessness.

Coat and energy changes, such as a dull coat, poor body condition, or decreased energy.

Puppies and kittens are especially vulnerable since their immune systems are still developing. They often require multiple screenings during their first year. Most intestinal parasites are easily treated once detected, so if you notice any of these signs, bring a fresh stool sample to your next visit.

Protecting Your Pet and Your Family

Some intestinal parasites can spread from pets to humans. Roundworms and hookworms are among the most common zoonotic parasites, meaning they can pass from animals to people, particularly children, who are more likely to come into contact with contaminated soil or pet waste.

Regular fecal testing and preventive deworming help protect everyone in your household. We recommend fecal exams at least once a year for adult pets, and more frequently for puppies, kittens, and pets with outdoor lifestyles or known exposure risks.

Many monthly heartworm preventives also protect against common intestinal parasites, such as roundworms and hookworms. We'll help you choose a preventive plan that addresses both.

Why does my pet need a fecal exam?

Fecal exams detect intestinal parasites like roundworms, hookworms, whipworms, and coccidia, even when your pet shows no symptoms. Some parasites can infect humans, so regular testing helps keep your pet and family healthy.

How often should my pet have a fecal exam?

At least once a year for adult dogs and cats. Pets with outdoor access, those who visit dog parks, or animals in multi-pet households may need more frequent testing.

Why do puppies and kittens need fecal exams at each visit?

Young pets are especially susceptible to parasites, which can be passed from their mothers or picked up from their environment. We test at each visit during their initial vaccine series to ensure they're parasite-free.

What parasites can a fecal exam detect?

Standard fecal exams detect roundworms, hookworms, whipworms, tapeworms, and coccidia. For persistent digestive issues, we may also test for Giardia, which requires specialized testing.

How do I collect a stool sample?

Collect a fresh sample (ideally less than 12 hours old) using a clean plastic bag or container. A sample about the size of a sugar cube is enough. Keep it refrigerated until your appointment.

Can my pet have parasites even if their stool looks normal?

Yes. Many parasites don't cause visible changes to stool, and infected pets may appear healthy. Routine screening detects infections before symptoms appear.

What happens if parasites are found?

We prescribe deworming medication based on the specific parasite identified. Treatment is typically straightforward, though some cases require multiple rounds and follow-up testing.

Can intestinal parasites spread to humans?

Yes. Roundworms and hookworms can spread from pets to people, particularly children. Regular testing and prompt treatment protect your entire family.

Does heartworm prevention protect against intestinal parasites, too?

Many monthly heartworm preventives also protect against roundworms and hookworms. We'll help you choose a plan that covers both.

My pet tested positive for Giardia. What does that mean?

Giardia is a microscopic parasite found in contaminated water that causes diarrhea and digestive upset. It's treatable with prescription medication, though some cases need multiple treatments. We'll discuss preventing reinfection.
