How long to leave dog without pottying. We are new to the dog thing. Our dog is 1 year old and he can go from 8 at night to 10am sometimes without demanding to be let out. We are going on vacation, and can have my nephew stay with him, but he has to work the majority of days where he would be out of the house for 9 hours.
