Let’s just put it this way, if she’s in shape, you’ll get tired first. 🙂 It’s a great activity. I’m lazy and have to find other ways to get our dog excersize. As far as training goes, I find it easier to train a dog to run than to walk. If they’re running then they aren’t as focused on their surroundings. However, it’s best to start slow. If you have a naughty walker, then start training there and gradually move up to running. If your girl is a pretty easy walker, then just give it a shot and see how she does. Go from there with training. The one thing I will caution on, DO NOT LET HER PLAY TUG-O-WAR WITH THE LEASH!!! It’s a favorite pit game and, once they get a hold of that leash, they can make you look very foolish while trying to get them to let go. The things you need to watch out for are pretty much just normal dog things, rather than pit-specific things. However, I always try and be mindful of the fact that other people may not be very comfortable with my dog. While I trust him, I understand that many people don’t. It would be unfair of me to ignore the fear that they have. I am always careful to keep Kaos close by me when we’re passing other people unless they express an interest. That’s just common courtesy though.
