we had a kitten once that didn't grow. SHE had bowel movements and ate just fine, i thought she was a midget cat. Ends up she had the nipple of a baby's bottle in her belly and somehow the food passed through but wasnt' absorbed. For my lab that was so sick he couldn't eat we did boil rice, and hamburger seperately boiling off the fat and then mixed the two together. I am a big big big advocate of nutrical. I understand the frustration of vets and finances. If it were not for the humane not for profit clinic here i could not have my dogs. I hope your pup is able to rid himself of this. I imagine there are a lot of dogs out there with more things in their stomach then we could even guess and their owners clueless. Dehydration is the worst sign so i hope they can set you up with a bag and you can at least do sub q iv to make sure he stays hydrated and suffers no kidney damage because of it. Sorries for you and your pup. Keep us posted! Will be sending good energy your way.
