I guess I misunderstood what was going to happen yesterday. I thought he was going to get tested to see if the treatment worked. But no... The vet told me they used to use 3 treatments to kill the heartworms. Then they found they could do one treatment and start on heartworm preventative in about two weeks. The heartworm preventative flushes the system of all the baby worms. He said LD would test positive for heartworms for about six months. Amazing. He said his heart and lungs sounded good so hopefully he's on the road to recovery.

The vet said he seems like such a happy dog. He told him that he was lucky to have found me. Made me blush!
