What many new dog owners don't realize is that this pulling can cause damage to a dog's spine and trachea when they pull too hard on a collar. Breeds with short necks are even more at risk for this type of injury.
So what's the solution? A dog harness. Unlike a dog collar, a harness fits around the front legs and low on the torso, taking the pressure off of the neck area.
Owners report they have much more control with aleather dog harness than a regular collar. Yet at the same time, this is a much more gentle way to teach your dog his walking manners IMHO.
