How often do dogs have to be tested for heartworms?
I've also been told by my vet that prescriptions through the mail are not safe for my pets. Is this true?
Dogs should be tested yearly if they do not take heartworm every month. If the dogs are on heartworm all year round then test every 2 years. The medication we sell is the exact same medications sold at your vet. You figure it out??. vetcare
