Giardia is a common intestinal parasite that causes diarrhea (often soft, greasy, and foul-smelling), most frequently in puppies, kittens, and pets from shelters or daycares. A single case is usually cheap and clears up with medication. The frustration — and the cost — comes from how easily pets re-infect themselves from the environment, so a "simple" case can turn into rounds of re-treatment. Here's the Canadian picture and the insurance angle.
What it costs in Canada
| Scenario | Typical cost (CAD) |
|---|---|
| Vet exam + fecal test to confirm | ~$80–$250 |
| Medication (fenbendazole and/or metronidazole) | ~$30–$150 per course |
| Straightforward single case — all in | ~$100–$400 |
| Recheck fecal test (to confirm cleared) | ~$40–$120 |
| Recurring / multi-pet household (repeat rounds) | ~$400–$1,000+ |
| Bathing + environmental cleanup | Mostly effort, not vet cost |
These figures are estimates for general guidance only, not quotes, compiled from publicly available Canadian veterinary pricing. A single otherwise-healthy pet is an inexpensive case. The cost rises with recurrence: giardia cysts survive in the environment and on the pet's own coat, so pets easily re-infect themselves, and in multi-pet homes it passes between animals. That means repeat fecal tests, more than one course of medication, and bathing/cleanup to break the cycle. Puppies and kittens can also get sick enough from the diarrhea to need extra supportive care. See How we estimated these costs.
With insurance vs paying out of pocket
| Scenario | You pay | Insurer pays |
|---|---|---|
| No insurance — single case | Full $100–$400 | $0 |
| Comprehensive policy (in force before symptoms) | Deductible + co-insurance share | Exam, testing, medication, rechecks, up to limits |
| Recurring / multi-pet (each covered pet) | Deductible + co-insurance per pet | Each insured pet's treatment covered, if not pre-existing |
| No policy until after the diarrhea starts | Full cost — giardia is pre-existing to any new policy | $0 |
Cheap to treat, annoying to get rid of
The medication side of giardia is simple and inexpensive — a course of fenbendazole, metronidazole, or both usually clears the infection. What makes giardia frustrating is reinfection. The parasite sheds hardy cysts into the environment and onto the pet's own fur, so a pet can swallow them again right after finishing treatment. That's why vets often pair medication with bathing (to remove cysts from the coat), a recheck fecal test, and cleaning up the yard and living space. In a multi-pet household, all the animals may need treating at once so they don't keep re-infecting each other.
Who gets it, and the human note
Giardia is most common in puppies and kittens and in animals from group settings — shelters, breeders, daycares, dog parks — where it spreads through contaminated water, feces, and shared spaces. It can occasionally infect people too, though pet-to-human transmission is uncommon; still, good hand-washing and prompt poop cleanup are sensible while a pet is being treated. Because it often comes home with a newly acquired pet, it's a frequent early-days vet cost.
Does giardia cost vary by city?
Very little. Giardia is diagnosed and treated at any general practice with standard testing and medication — no specialist or emergency element to concentrate the cost regionally. What actually drives the total is whether it recurs and how many pets are involved, neither of which depends on your city. It's one of the more location-neutral conditions on the site.
How insurance covers giardia
Comprehensive (accident-and-illness) pet insurance covers giardia — the exam, fecal testing, medication, and rechecks — provided it wasn't pre-existing before your policy started. The usual real-world catch: a newly adopted puppy or kitten that already has giardia is pre-existing to a policy you buy afterward, so getting a new pet checked and insured promptly matters. Because a single case is cheap, insurance matters less for giardia alone than for the bigger, unpredictable conditions — but a comprehensive policy covers all of it, including the repeat rounds if it recurs.

Considering insurance?
A single giardia case is cheap, but a recurring or multi-pet infection — or the newly adopted puppy that brings it home — costs more and can be pre-existing to a late policy. Insure a healthy pet before symptoms and infections like this are covered, along with every bigger risk. Compare Canadian plans.
