Why Heartworm Prevention Is Critical in Canada

Heartworm disease is transmitted by mosquitoes and has been reported in every Canadian province. Infected mosquitoes are active from spring through fall, and in some regions year-round. Heartworm larvae mature into worms that live in the heart and lungs, causing severe, life-threatening damage. Treatment is expensive, risky, and hard on your dog — prevention is simple, affordable, and highly effective.
