When I was a kid when the heartworm meds just came out, we were giving our dogs the preventive. We got a new dog that had been a stray and when we gave him the heartworm preventative, it released the heartworms into his system and killed him.
So I have always been terrified to give a dog heartworm meds until I was sure they didn't already have them. Maybe the meds they used in the 70s were different, but that left a real imprint in my mind.
So be careful about that.
