we must be browsing the same other forum. i just saw that on another one too.  my opinion on that is : the one thing that bothers me is...they took the dog in to be put to sleep, yet a couple of days later the dog is returned to them and RUNS to greet them. doesnt sound like he was on his death bed to begin with. maybe the vet was just trying to save the dogs life, which in all reality he did.
