The third hand on your bike that makes cycling with your dog safer, easier, and more enjoyable. Special design reduces your dog's tug by up to 90% and keeps your dog away from the bicycle wheels. So now you can give your dog all the exercise it needs and longs for. Easy to remove when you want to ride without your dog. Can be mounted on either side or can have two on one bike as one of our Husky owners has to train during the off season!
