I strongly suspect one of my dogs has it. He started hacking a dry cough a few months ago and the vet poo-pooed it, but he is still doing it and he is panting a lot. This started after all three dogs had a bout of kennel cough, but his never seemed to go away, and the other dogs haven't gotten the cough back. If he had kennel cough, the other dogs would have caught it from him. I think it's probably in the early stages. If he has it, how much does it cost? I have to treat it. I know I should have had them on heartworm preventatives, but until this year I honestly didn't know how much an indoor dog needed it. I have already ordered heartworm preventatives online this year, but it may be too late for my girl. Thanks!
