Small parasites, real risks

Fleas cause itching, allergies, and can infest your home, while ticks in the Niagara region can transmit Lyme disease and other illnesses. The good news: nearly all of it is preventable with a consistent, well-chosen plan.

We recommend products based on your pet's species, age, weight, and lifestyle — because dogs and cats need different protection, and an indoor cat's needs differ from a trail-hiking dog's. If parasites are already present, we'll treat them and help you clear your home.

Don't forget heartworm

Heartworm & heartworm prevention

Heartworm is carried by mosquitoes rather than fleas or ticks, but prevention fits naturally into the same routine — and it's a serious disease that's far easier to prevent than to treat.

What heartworm is

A single mosquito bite can pass on heartworm larvae, which mature into worms that live in the heart and lungs. Left untreated, it damages these organs and can be fatal — and signs often appear only once the disease is advanced.

  • Spread by mosquito bites, so risk climbs through the warmer months.
  • Most common in dogs, but cats can be affected too.
  • Early infection usually causes no visible symptoms at all.

How we prevent it

Prevention is simple, safe, and highly effective — usually a monthly chew or topical during mosquito season. Many products also cover fleas, ticks, and intestinal worms at the same time.

  • A quick annual blood test before starting or renewing prevention.
  • Monthly preventives through mosquito season, or year-round for full cover.
  • Coordinated with your flea and tick plan so nothing is missed.

Not sure whether your pet is protected? We'll review their history and recommend a simple heartworm plan at your next visit.

Frequently asked questions

Does my indoor cat really need flea prevention?

Fleas can hitch a ride indoors on people, dogs, or other pets, so many indoor cats still benefit. We'll help you weigh the risk.

When is tick season in our area?

Ticks are most active in spring and fall but can be found whenever it's above freezing — which is why year-round prevention is safest.

Oral or topical — which is better?

Both work well; the best choice depends on your pet and your household. We'll recommend an option that fits your routine.
