do dogs always have a cough if they have heartworms? General Dog Discussions
Someone told us that our 10year old outside dog has heartworms because he won't eat nor drink very much. He will eat a little chicken breasts ( maybe 2 little pieces at a time) and a little water if we hold a bowl in front of him. I have even given him a couple of tablespoonfuls of Karo syrup. He does not throw up nor has blood in his stool. We were also told that if he has heartworms that he would be coughing, but he doesn't. He has lost weight.
