He used to be excited to see me, now he doesn't really and wags his tail a little bit when he see's I'm coming, then when I touch him he hides his tail... he still eats and drinks normally. He breaths in deep breaths, but he does that a lot. IT kind of sounds like his nose is clogged. He is a Dachshund dog, and he's a little bit over weight but that's because he's a bigger dog than most of the dachshund dogs.
