I am wanting to know if I would confuse my yorkie if I start training him to go in the house and after a short time (winter in iowa brrrr) train her to go outside would she be confused if when winter comes she pees in the house in a specific spot and when not winter (no snow) she can go outside. I really want mine to be trained to go outside to pee n poo but don't want to confuse her. Help please.
