I recently had my pet in Tennessee for a visit. I treated him with a flea medication before I left but it didn't work. He went through a tough time there, but Advantage finally got rid of them. Now I'm concerned, someone told me that all dogs taken south get heartworm. Is this true and if so what should I do?
No, this is not true but you should have your pet tested for heartworm disease if he was exposed to mosquitoes. vetcare
