In my experience, these types of leashes a.) tend to cause
dogs to act more aggressively and to pull hard on the leash; b.) are more likely to trigger a fight
with another
dog since the
dog that is straining at the end of the leash looks like it is in attack mode; c.) tend to be purchased by lazy and irresponsible
dog owners who do not train their
dogs to obey, and who tend to spoil their
dogs, causing more aggression and bratty behavior; d.) undo most of the important aspects of your obedience training and leadership over your
dog, especially obeying around distractions and coming when
called, and over time they teach your
dog to charge after other
dogs, animals and even people; e.) are hard to control once the
dog is at the end of the line, and can get caught in the leashes of other
dogs, increasing the potential for a biting or attack incident; f.) do NOT cause the
dog to get more
exercise on the walk; g.) can cause a
dog to run away from you, because if you accidentally drop the leash handle, many
dogs will run from the plastic handle «chasing» them from behind and that could cause your
dog to run into traffic and die; h.) have resulted in injuries to
dogs and owners.
Agility — a handler directs a
dog through an obstacle course in a race for both time and accuracy Obedience Trials — Obedience competitions begin
with exercises that attest to the
dog's good manners — walking on a leash at the owner's side, standing to be touched by a stranger, sitting and lying down
with distractions, and coming when
called.
You can also provide ramps where a
dog needs to climb stairs, take shorter but more frequent walks, provide opportunities to swim or have other non-impactful
exercise, provide him
with an orthopedic bed and elevated food and water dishes, and even simple measures like not
calling him to come to you when he's lying down unless it's necessary.
