I "walk" the girls to the park that is 3 blocks away and let them run till they are tired, I dont do this everyday though, I usually take em out in the back yard and play frisbee or play fetch or play with the hose. currently though they are still tired from the herding clinic lol and after seeing Misty THAT ired, I dont want her to be that tired all the time lol she is usually the dog that keep the smile on my face, but when she is exuasted all she wants to do is sleep and I dont get to see that big Misty grin and fun attitude I miss it
