Comfortis Plus is an all-in-one parasite prevention treatment trusted by vets and pet owners worldwide. Designed specifically for dogs, this convenient monthly chew protects against fleas, intestinal worms, and deadly heartworm — giving your dog broad-spectrum protection in one tasty, easy-to-administer tablet.
Each Comfortis Plus chew starts working quickly, killing fleas within 30 minutes and eliminating 100% of adult fleas within 24 hours. It also prevents flea infestations by breaking the life cycle and stops heartworm disease before it can start. Plus, it effectively treats and controls common intestinal worms, including roundworm, hookworm, and whipworm.
Comfortis Plus uses the active ingredients spinosad and milbemycin oxime — a powerful duo that works together to target both external and internal parasites. Spinosad rapidly kills fleas, while milbemycin oxime provides lasting protection against heartworm and intestinal worms.
The Comfortis Plus range at CanadaVet includes chew sizes for dogs of all weights — from small breeds to large dogs. Each pack is clearly labeled for easy selection and provides one month of full-body protection per dose.
Unlike topical treatments that can wash off or leave greasy residue, Comfortis Plus chews are mess-free and water-resistant from the inside out. It’s ideal for active dogs who love swimming, baths, or spending time outdoors — and perfect for owners who prefer a simple, oral solution.
At CanadaVet, you’ll find genuine, vet-approved Comfortis Plus chews at competitive prices — no prescription required. Enjoy the convenience of fast, reliable shipping straight to your door and give your dog the protection they deserve.
With Comfortis Plus, keeping your dog safe from fleas, worms, and heartworm is easier than ever. Explore the Comfortis Plus collection today and enjoy the peace of mind that comes with year-round parasite prevention.
