I have a 12 year old male Basenji and lately he's been acting strange... he's restless and just can't sit still for too long. Sometimes he'll eventually fall asleep, but usually I get woken up in the middle of the night. He'll lay under small tables or little nooks that he's never been under. He whines and moans a bit... it just seems like something is bothering him but I have no idea what. I don't notice anything else strange with him, so I'm assuming it's something internal. Any ideas?

Sounds like your Dog is in pain, especially with the hiding away in the nooks etc. VET time I think??

Hope all is well.
