My three-pound Pom boy, Little, has me terribly worried. I found a tick on his head and tried to pull it out. Well, it sort of got cut in half and now part of the tick is stuck just an inch above his eye with the area around it quite swollen. I've applied hot compresses to stop the swelling, but what else should I do? I'll be calling the vet's tomorrow as well (they're closed now and this hardly qualifies as an emergency), but should I be worried?
