I take Chewy out every hour to make sure there are no accidents inside. I also take him out at 3 at night and 6 in the morning and then every hour after words. My mom would hate him if he peed in her house. The problem we have with Chewy is he gets exited and pees. He peed on my sister just a little bit ago. LOL. We told him he was bad and put him outside. He is staring to get the idea.
