If your dog has behavioral issues, it is best not to utilize a leash that is more than four or five feet long or a retractable leash. This can allow dogs to get too far away from you and will enable them to believe that they are leading you, which in fact they are.
Retractable and longer training leashes are fine if used to allow dogs a little more freedom at a park or play area. But consider that as you walk, and your dog is twenty feet away from you, you are teaching him that he is the leader. Have a short leash available for the walk to or from the area that you will use the retractable.
Retractable leashes now require a warning of strangulation possibilities, amputation possibilities and other cautionary statements. We have seen many times where a dog gets his tail, leg or even neck tangled out in a retractable leash and then spooks and bolts causing injury up to and even including amputation.
Retractable leashes are also quite cumbersome so it makes life a bit difficult if you have to manage holding a stroller, bicycle handle, toddler’s hand, etc.
A head halter is similar to a bridle or halter on a horse. They enable you to control the head and the body will follow where the head goes. Never use a retractable lead while also using a head halter. It can cause the dog to injure its neck as it runs to the end of the retractable.
Elasticized leashes can be helpful but also quite difficult to control your dog. They are confusing, it is hard to tell where it begins and where it ends.
Fancy decorative leashes are fine but make sure that they are strong and will not break easily. Also check to make sure that the hardware or clasp on the leash is strong and secure. Some clasps will easily open and could allow your dog to run off. Test your clasp well before purchasing it and well before each use. It is common for spring loaded clasps or clips to outlive their usefulness so check each time for safety.
