Hi and WELCOME to YT
! Glad you found us. There is a wealth of info here, as you've already noticed. Keep asking for advice, and keep reading - and I know you'll get your kiddo to the right training place.
As far as time-outs, lol, I'd ignore that one completely. Dogs have NO IDEA what a "time out" is or that it's punishment. A time out does nothing. Also, punishing a dog for peeing is only going to confuse them and make them want to pee in hidden places, and you don't want that. Skip punishment altogether. When he pees in the wrong spot, say NO, pick him up, bring him to the pee spot and say "go potty here".
