Found a stray in my neighborhood and he was skin and bones. I knew if he went to the pound he would be euthanized within days. I kept him and took him to the vet for a checkup and of course he’s heart worm positive. Got him started on the treatments and he’s doing well. Problem is, he and my lab have been at each other since almost the beginning. They fight about any and everything. The other night it was so bad, one of them was bleeding at the neck. Also, they’ve both began peeing in the house. I can’t even have them in the house any longer. I know my older dog is jealous of the new one and he’s acting out so I’ve had to put both of them outside. Question is, do I keep him do I try something else? I don’t know what to do.
