I boarded inside my home. I will only board dogs that are crate trained. I happy to crate train if you desire for your dog to be crated. They are never left unattended. I am in and out through out the day, but dogs do not go very long in a crate at one time. When I am home I let the dogs out to take turns to free roam around my home and get some pets and snuggles as well. I do not take more than 3 at once. My yard is big and has a brand new and safe privacy fence
