My poor pooch gained a ton of weight after his neutering, He weighed in at ten pounds when he went for his neuter, I took him to the vet a week and a half later and he had already gained over a pound, thats alot for a small dog. His hair dried out and he is now around 16 pounds less than a year later. People will accuse me of overfeeding etc, but the dog isnt free fed and I can assure you he eats no more than he ate prior to the neutering.I think they removed his thyroid instead of his testicles!!!!!!!!! Has this happened to anybody else out there?
