Here is one of the things I like to do with the big girls. We have this great stretch of grass on a ridge that is great for biking. I love it because I can see all the way to the end about 4/10ths of a mile a way. I can see if I have the path to myself or if other people and dogs are up there. It is such a great way to gallop the hounds at an easy pace for a couple of miles. We have to go down and back a few times, but I reward them with treats at each end so they are motivated to keep going. It is such a great way to exercise Seven when I am trying to avoid sharp turns.
Remember that Seven is very well trained and very responsive. If I was not certain of her responsiveness around people, dogs, or the other distractions at this location, I would not have her off leash. Plus she is a movie star. Ha!
