My dog has never had these symptoms, but truly your dog should be taken to the vet. I know that animals take longer to show symptoms than humans do - they could be running around sick and you would never know it. By the time they start acting like somethings wrong, it's probably reached the point of critical. My dog had a double ear infection and SEVERE bladder infection, and was still running around playing like a puppy (at 5 years old). I read somewhere that breath that smells like gasoline (not that you said gasoline, but I thought I'd throw it in there) is a kidney problem. Fever, listless behavior, not eating, not wanting to bark all point to a doctor's appointment!!!!
