Deworming is one of the smallest line items in pet care, but it's also one of the most common questions new owners have — especially with a puppy or kitten, which are almost always born with or quickly pick up intestinal worms. Here's what deworming costs in Canada for dogs and cats, how often it's needed, and the one thing to know about insurance.
What it costs in Canada
| Scenario | Typical cost (CAD) |
|---|---|
| Single deworming treatment (by weight) | ~$20–$80 |
| Fecal test (to identify parasites) | ~$30–$60 |
| Puppy / kitten deworming series (first months) | ~$60–$200 total (often bundled with vaccines) |
| Prescription dewormer for a specific parasite (e.g. tapeworm) | ~$20–$60 |
| Broad monthly parasite preventive (also covers worms) | ~$15–$40/month |
These figures are estimates for general guidance only, not quotes, compiled from publicly available Canadian veterinary pricing. Cost depends on your pet's weight (dewormers are dosed by weight), which parasite is being treated, and whether it's a standalone visit or bundled into a puppy/kitten package or a monthly parasite preventive. Many owners cover intestinal worms through a broader monthly preventive that also handles fleas, ticks, or heartworm. See How we estimated these costs.
With insurance vs paying out of pocket
| Scenario | You pay | Insurer pays |
|---|---|---|
| No insurance | Full cost (small — it's a routine item) | $0 |
| Standard comprehensive policy | Full cost | Not covered — deworming is routine/preventive care |
| Wellness / routine-care add-on | Reduced, if the add-on lists it | Some plans reimburse routine deworming — check the wording |
| Treating illness caused by a heavy worm burden | Deductible + co-insurance share | Illness treatment may be covered (if not pre-existing) |
Why deworming matters (and why puppies and kittens need a series)
Intestinal worms — roundworm, hookworm, tapeworm, whipworm — are extremely common, and puppies and kittens are often born with them or pick them up from their mother's milk. That's why the young-animal deworming schedule is a series of treatments spaced through the first few months, usually done at the same visits as the puppy or kitten vaccine rounds. Adults are dewormed periodically based on risk — hunting dogs, cats that go outside, and multi-pet households need it more often than an indoor-only pet. Some worms (like roundworm) are also a human health concern, which is another reason routine deworming is standard advice.
Deworming vs a specific infection
Routine deworming is cheap and preventive. That's different from treating a diagnosed parasitic illness — for example a heavy worm burden causing weight loss and diarrhea, or a specific protozoan infection like giardia, which needs its own targeted treatment and follow-up. If your pet is sick from parasites (vomiting, diarrhea, a pot-bellied puppy, visible worms), that's a vet visit with diagnostics, not just an over-the-counter dewormer — and the cost sits higher than routine prevention.
The insurance catch: routine care isn't covered
Here's the one thing to know. Deworming is preventive care, so a standard comprehensive accident-and-illness policy won't reimburse it — the same way it won't cover vaccines or a routine check-up. Only a wellness add-on covers routine deworming, and only if the add-on lists it, so check the wording. What insurance is for is the unexpected illness and injury — if a parasite burden makes your pet genuinely ill and needs diagnostics and treatment, that medical care may be covered (if it isn't pre-existing). The routine dewormer itself, though, is a small out-of-pocket cost you should simply budget for.
How we estimated these costs
The dollar figures here are estimates for general guidance, not quotes, compiled from publicly available Canadian veterinary pricing. Real costs vary by clinic, your pet's weight, the parasite treated, and whether deworming is bundled with vaccines or a monthly preventive — confirm with your own vet. Sources we drew on:

Over-the-counter dewormers
For routine deworming — confirm the right product and dose for your pet's weight and parasite with your vet:
- Natural dewormer — dog & cat (made in Canada) more options
- Broad-spectrum dog dewormer (tablets) more options
- Monthly parasite preventives

Considering insurance?
Deworming is a $20–$80 routine cost — small, but insurance won't cover it unless you have a wellness add-on. What comprehensive insurance is really for is the unexpected illness and injury that run into the thousands. Budget for routine care; insure for the big stuff. Compare Canadian plans.
