he takes 1/2 a pill of previcox a day for pain...he's had no issue for it as he has been on it for a while now.
Not sure if they checked for stones. All I know is that they took blood to check for pancreatitis.
He never appeared to be in any pain (no yelping when I picked him up, and no yelping when the vet felt his belly and everything)...you could just tell my poor doggie was miserable though
