Sounds like you've got one very lucky puppy dog on your hands. :)
I would think something like chicken & rice, extremely small amounts would be ok to start, or a good convelesent diet is Selected protein veterinanry diet avavilable from your vet.(It is nice & mushy & is full of good nourishmennt for dogs recovering from D# or post op dogs)
Tohme is very knowledgable on all aspects of feeding, I'm sure she'll advise if she spots the post.
good luck with your pup & keep us posted. :)
