We had a friend of ours who's little bully had an obstruction and our vet operated on her. We brought her to our house after the surgery and kept her for a week to make sure she was OK. Not sure if they cut out any intestine or not, but I do know cutting out a small piece will not hurt anything. Just keep him as calm as you can and feed small portions of food several times a day for about 10 days, or do what your vet tells you to do. That's what our vet said to do with the food. We fed her soft food for about a week and then slowly added the hard kibble. After the week was up and she was doing fine, and she went home to her momma and dad.
