Taking your dog for a brisk walk is a great way for both of you to get exercise. Regular walks keep dogs balanced, happy, and calm. A walk can turn stressful, however, if your dog is constantly pulling. We've tried just about every kind of technique, collar and leash to reduce our large dogs from their natural desire to forge ahead. The best device we've found is the Gentle Leader Easy Walk Harness. Since the leash attaches to a martingale loop on the chest, the dog is not pulling at the neck. It is cleverly designed with a different color-coordinated belly strap so you can easily identify the right way to put it on. This harness almost instantly made walking our two big dogs a more enjoyable experience. The harness is available in various sizes and colors from Cherrybrook.
