My best buddy, a 13 yr old heeler cross, spent last week in the hospital with pancreatitis. This was brought on, I think, by eating a pizza he found. He survived, and came home, but still isn't eating anything. He drinks and pees ok, but won't eat anything. It's now 1 week since he ate anything and kept it down. He's weak and tired, but can walk around a bit. No fever. Is he going to get over this? Will he start eating before he starves to death?
