We prefer small and medium sized dogs as that's the size of our dog, Luther. He's a fun-loving maltipoo who has never met a dog that he wasn't up for playing with. He's pretty much as social as they come! We have a nice fenced front garden and backyard with several expansive schools and (dog) parks nearby within walking distance. We've had many very positive experiences dog sitting on Rover over the years, and taking care of neighbors' pets. Our kids have loved dogs since they were little. My son interacted with dogs every day at school while he was at the California School for the Blind.
