That's great to hear, such a difference when you really get to enjoy your dog again! We found the same with Ollie after neutering - the day to day bolshiness, constant guarding and body handling issues dramatically reduced. We couldn't get near him in a park if he found food, or a female he wanted to associate with, and he thought nothing of seriously snapping during handling. Don't get me wrong, we still have real issues with guarding and nervous behaviour at times, but we don't have the constant challenges in so many areas that made daily life such a strain.
