I was went into the county shelter the other day (dangerous, I know), and noticed a 3month old male puppy that was neutered. Recently I've noted a lot of puppies being neutered earlier than 6 months. When I worked at the kennel I had started to notice it-a 3month old pup would come in, and would claim to have been fixed already.

I'm just curious if there's a new procedure out there, that you can get it done earlier than 6 months? Or is this dangerous? I'm just curious, to my own personal knowledge.
