Gentle leaders should not be used for all dogs for several reasons. There are times when they just aren’t appropriate. First of all, these collars are only meant for walking. You cannot keep them on your dog at all times. As a result, your dog will also require a separate collar for other occasions.
In addition, gentle leaders do not train the dog themselves. They work best when used alongside training techniques that can reduce your dog’s reactive behavior. It’s a band-aid, not a solution. It is still possible for your dog to be reactive when you start using a gentle leader without training. Until your dog is properly trained, you will need to use a gentle leader every time.
