This is our Border Collie/Husky mix. She requires plenty of exercise so the best way I have found to give it to here is to take her out on my Mt. bike around the neighborhood. I use a regular 6 ft leash attached to a x-back sled dog harness. The leash is attached to the bike with an old piece of bike tube to allow for a bit of give when she accelerates. All she needs now is a partner!
