Something I really like about the puppy room is the doggy door. The pups start using this door about week 5. By the time week 8 comes around all the pups usually understand the concept of leaving their living space and going to do their business outside. If you get a pup from Brown’s Labradoodles and have a doggy door, the transition is pretty easy. The doors can be installed in walls or doors. On Amazon I have seen a panel that has the doggy door in it, that can be used with a sliding glass door. Having a dog that uses the doggy door to go out of the house into a fenced area saves a lot of work and is a win for the dog and the owner.
