Maybe I am doing it wrong....? They are 3.5 months old, and we have had them for a month (Raven) and a month and a half (Freya) and I know small dogs take longer and Tzus are some of the worst with housebreaking! But, they don't in any way seem to grasp the concept that they should not pee in the house. We will go outside and do our business, then come in and literally....20 minutes of play time, and someone is squatting to dribble a bit on the floor!! And with no shame....when i see it and give a firm "NO" and run over to stop it, either one of them will just continue to do their business
