A dog leash is a kind of rope that is used to control an animal by attaching it to a collar, harness, or halter. Leashes were used to walk the dog in public. And for safety reasons also as a loose dog can cause accidents or if it was to become aggressive their owner has some form of control. The length of the leash is also one of the important aspects that we have to see before buying it for our pets. The length should be according to the size of our dog because it allows good control.
