Welcome to the world of bullies! Just like our 2 legged kids, they make us worry so! I felt the same way with each surgery my pups had. If you trust your vet then don't worry. Just think how much he will love you when you pick him up!
Awww glad he came out of it ok and is sleeping by you. Sorry I didn't send my well wishes early too. It's always unnerving when they go under.
