I have a fenced backyard and live on a quiet street with a cul-de-sac. We have an upstairs and downstairs but have doggy gates to keep areas fenced off depending on what you're comfortable with. We also have child safety locks and a very energetic 4 y/o who's been dog-trained and is very gentle. Even though he's great with dogs and animals, I never would leave him unsupervised, for his safety and the pet's. Our previous dog sitting clients have really loved that their fur babies get such an energic playmate. We have a park nearby as well with plenty of green space and I am happy to do whatever your dog's favorite activity is.
