Max is sluggish and doesn't want to move. He sleeps all day. He's usually jumpy and playful but this morning isn't a healthy day for him. What could be his problem?

What is Max and any other information would be useful ?

He's a 1y/o shih tzu. :(

Is he up to date with vaccines/worm/flea medications? Could he have gotten into something he wasn't supposed to (cooked bones, garbage etc... )? Could he have hurt his leg playing? Any other symptoms like vomiting, diareah, is he eating and drinking? Has there been any changes in the house, people moving in or out? How long have you had Max for?
