Living in Calif till 1995 meant I knew nothing about heartworm.
I have had one rescue dog present positive for heartworm. It was early stages and kept on heartguard - did not test positive when re-tested later. This was in Texas He found a home with a neighbor. We called him Dog.
I am trying to remember the name of another dog that had heartworms. It was an OLD found dog that the vet and I agreed the HW treatment would kill the dog. He did a monthly check up. when it began to suffer we had him put to sleep.
Horrible times. This was early days at BOR.
