My one pound puppy fell of the couch a few times... she was frightened and a bit cautious to move, but otherwise she was fine, im not sure if she wanted to sleep much after wards or not- but was he playing a lot before he fell?? puppies normally sleep 15-18 hours a day, so he could of just been tired. Call your vet, see what he/she has to say... Im sure your baby's fine- he's just a puppy!!!
