This questions is for all you breeders out there. How many of you heartworm test your dogs? How many of you do spot ons for fleas and limes shots and everything else? I worm and give my own shots every year except rabies. The vet comes to my house for that. Any other problems they go into the vet. I won't dock my cocker's tail myself or do dew claws either, they will got o the vet for that. But I don't know of any breeder's who heartworm test there dogs. So far I am the only one who does the flea treatments and the yearly shots. Should I also be doing heartworm?
