My two Pittbulls had an altercation, and the end result is that the one has several picture wounds around and on his ear, and the entire side of his neck and face are very swollen. I took him to the doggy emergency room and they wanted a ridiculous amount of money to even look at him. I brought him home and have been giving him human amoxicillin, and cleansed the wounds. Is this okay or dj I need to do more? It appear that the swelling is going down. ease help me....
