I am bumping this for you, sorry I don't have any idea about the change for him. I had my pup neutered about 1.5 weeks ago, and he was YES ANNOYING for ONE day, and I felt we were back to when he came home.....he was naughty, and grabbed things and ran with them when he knows he shouldn't have, but it just lasted the one day. Are you ignoring his whining? That may help....maybe you just have to do what you did from the beginning, ignore and it will subside??
Good luck!! |
