I am moving from a house to an apt. I have only had Prince for two weeks. I have been training him to go outside. Will it be possible for him to do both? I work and go to school I dont want him to have to hold it too long. I started leaving him in the crate when I am gone for longer hrs each time. But he started peeing in the crate now. What should I do? Play pen for the day and pee pee pads?
