BJ is a full grown adult lab mix. He ate a rabbit head about 6 days ago, he vomited bile the night before last, he is incredibly active usually and is now very lethargic, he does not lift his head when someone walks into the room, does not wag his tail, has a temp of 105 F, limping and abnormally bad breath. Have given him a synovi chew and a baby asprin, Did not seem to help. Can you help me please?
