I let them in my half acre yard and they have a ball. Running all day long especially if it’s nice out I have pools to cool them off as well as ice cold water for them. Let them in and play with them then they are all tired out and take a much needed nap. And back up again and play for a few more hours running after balls outside and swimming in the summer. They love it especially if is snowing out the fun they have dashing in the back yard is so much fun to watch. I have always had dogs all my life and enjoy every minute with them. I am 58 and still enjoy every minute of it that’s all
