Would you put your dog in obedience school?

I'd only use formal obedience training as a last resort to be honest, as in the past I've always been able to train my dog to be house trained myself.

In my opinion all it takes is a lot of patience, care and attention, and if you can't give any pet that, then maybe you shouldn't have a pet that needs to be trained in the first place, and maybe better off with tank or cage based pets.
