I have two puppies of my own, one small and one medium dog. The medium sized dog is half retriever half hound, his name is Kato. My small dog is named LB, he is half toy poodle half shih tzu. They are both high energy dogs that love to play. I have a larged fenced in turf yard for the doggies to play on with a giant fountain to cool down in. The turfed area is always full of dogs for them to play with. Kato &. LB love having other dogs to play and share their toys with. I am home most of the time, it is rare that I am gone for more than 2-3 hours. During the period that I am gone I do let the dogs run loose or I put them in a large pen where they have plenty of room to roam around.
