What About Heartworm Resistance? 

Heartworm Drug Resistance: It’s real! Recent evidence indicates that a dog faithfully given heartworm-prevention medication may still become infected with heartworms. Convincing evidence of resistance was presented by multiple researchers at a meeting of the American Association of Veterinary Parasitologists. Because of this, the American Heartworm Society advises an annual blood test, even if they are on year-round preventative.
