When I started training dogs over 20 years ago virtually all dogs who were in training wore astounding dog correction collar. Although I used astounding dog correction collar for many years I never use them now that I have a better and more effective set of skills. Before I tell you why, let me first explain how a astounding dog correction collar is used.
By far the most common collar is the astounding dog correction collar that fastens with a plastic clip or a buckle. These collars are the most convenient to slip on and off and are handy because they can hold your dog's identification, rabies, and license tags. Even though this type of collar retains its size, the collar can become a hazard. Dogs playing roughly and in a mouthy manner can get their mouth caught in the collar of another dog, causing panic in one or both dogs. As they struggle to get loose, the collar can tighten and dogs have suffocated as a result of this type of play. Dogs who are the object of this type of rough play should wear break-away collars, similar to the break-away collars in cats, at least during play and unsupervised times. Some owners opt to avoid collars or any gear at all unless they are taking their dog on a walk. Although this in an option, I prefer to have visible identification on my dog at all times and a collar with its tags is the most convenient way to do this.
