Your dogs will enjoy long walks and play time. Size does not matter I have watched dogs from 1 to 150 pounds. I can travel to you or you can drop off i can walk your dog 3 to 4 times a day 7 days a week. During the summer heat prefer to walk early in the morning or evening to ovoid heat problems. I enjoy spending time with all my fur babies playing fetch or tug a war or just belly rubs i could do short to long visits. Over night stays your dogs can sleep in bed or by the bed i will not use a cage unless requested. I have a jack russell he gets along with all dogs and loves to play.
