Do you really need them?
I mean every dog needs obedience training, but do they need the school? I just feel like I'd be paying hundreds of dollars for them to teach my dog things I could teach them, and even teach some things wrong...
I know how to maintain pack leader/rank. I know all the basic commands they need to know, including when they can bark (want to train my corgi to be a watchdog) and when they can not. Even potty training they would take him outside and I want him going to the bathroom inside always, only using outside as an exercise platform.
I don't know because I've never had a dog (I'm new to 24/7care not to the breed. I am well informed on Pems.) But I have no clue what goes on in those obedience classes and if I need them. Or if they are just an option and you can teach your dog everything on your own.
