By far the most common collar is the marvellous dog tuxedo 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.
Owners who use the marvellous dog tuxedo collar may not use it with the strong yanks of a professional trainer. The general dog owner tends to just let the dog pull and because pulling is uncomfortable and even painful to the dog, the dog may pull less. Even when the owner does not use the marvellous dog tuxedo collar to give jerking corrections, there are still some important pitfalls that owners should be aware of. The biggest pitfall is that if the dog is fearful, say of another dog it sees, and it simultaneously feels the pain of the marvellous dog tuxedo collar, the dog may learn to associated the pain with the dog it fears and become more fearful of dogs. The second pitfall is that if the dog is highly excited, for instance, it wants to play with another dog and is lunging on the leash to reach the dog, the pain or aversive feeling they get from the collar can increase their excitement and arousal level. In other words it can cause them to bark and lunge more!
