Finally a big dog tactical collar designed right. As big dog owners we can’t simply walk into a pet store and readily find dog collars, leashes, or harnesses that can withstand the pulling force of a powerful dog breed. Check out the BuffK-9 big dog tactical collars, leashes and harness line. They feature stitching throughout the entire collar in key areas, cobra buckle to withstand up to 880lbs of force and a heavy duty D ring. Not to mention the awesome looks these collars give your dog.
