I agree with Logan. It is one of the best things you can do for a dog. It reduces the risk of overpopulation of animals and it increases the risk of certain health problems. I think that if any dog suffers from depression, it would only be for a brief period of time. The sleeping I would assume is from the anesthesia and it wears off after a few hours or a day. I had a dog neutered when he was four and the only regret I have was not doing it sooner.
