Planning on adopting a puppy at 10 weeks old, the dog was a large breed and was neutered without our knowledge before adoption. If large breeds are neutered early it can cause ruptured ligaments and other serious issue related to hormonal imbalance. No one wanted to talk to us when we called with our concerns about early neutering. On paperwork it said we had the option to neuter him at our own vet but we're not actually given that option.
