Doggie shower in garage. Love this idea. Also seen it done like a mud room with a door to the exterior so the dogs can go in and out but can be closed off from the rest of the house (like a giant dog house with all the amenities attached to your house!
Awesome dog kennel under the stairs design idea. If you want an indoor dog house, utilizing the space under the stairs for a cozy, attractive and practical space for dogs is a good idea! The barn door really ties it together.
