first of all i take my hat off to you for sticking with him and well done. secondly , i know the vet wanted to put him to s - - - p, but i would take him back to the vets and show her the dog, and tell her what you did , so she doesn't make the same mistake with someone else's animal. everyday we All learn something new, so i think its best to pass on this knowledge (as it looks like this vet needs all the help she can get) . well done
