It's possible that he is sore from his tussle with the other dogs. I recommend that you take him in to your veterinarian to be checked over. If he got bit anywhere, it may be forming an abscess, which could cause him to be lethargic. and feel sick. Or, he may just be generally sore if he got knocked around a bit. Either way, it would be best to have your vet do a thorough physical exam to be on the safe side. If your vet thinks he is painful, he can prescribe some pain medication.

    He may appear sad because he may be in pain from teething. If he appears lethargic or is not eating and drinking well I suggest you take him to a veterinarian for a wellness exam. You can also try various feed, hard and soft to find one that may hurt less when eating.
