BTW - He is not behaving as if he is sick. When he is awake, he is full on play - chewing anything he can, playing with his special chew bone, playing tug of war with his tug toy, running all over (I even got down on all 4's to play with him and he chase me around as if I was a puppy too) and he is eating and drinking and taking care of his business. He drinks a lot too. It's been a long time since I had a puppy and I don't remember how much they drink. I was surprised.
