We have a big yard with 1 kennel. Dogs can roam freely (if trained) also can come in house, use kennel, or even can set up access for runner if preferred. Can also walk dogs with leash. We do have one dog, a rottie named Tyson. He is a big baby, he has been in contact with all dogs big and small, Male and female, fixed or not, and has been submissive to all animals. He does guard his food bowl but is/will be fed away from other animals.
