He is not lethargic. Mucus membranes pink and moist he is drinking OK. He eats Science Diet dry with a small amount of wet food treat. He weighs about 39 lbs. When Mike walks him he eats anything he can find before he stops him so I don't know. The only meds are for pain but he has had none since last month and he is on flea and heartworm med orally. He was attacked by a Boxer a year ago and his hand leg ripped open and surgically repaired, hence the pain. Otherwise he gets a clean report from the vet. No way to take his temp.
