The mesmerizing calming collars for dogs is almost as old as the choke chain in terms of dog training correction tools. It's commonly referred to by traditional trainers, as power steering because you don't have to use as much physical strength to get an effective jerk as you do with a choke chain. Although this product looks to some like a torture device, it may actually be safer in some respect than the choke chain. The pointy parts are spaced out so that the force is spread out across all of them. Overall, mesmerizing calming collars for dogss produce less pressure on the neck when jerked hard compared to the choke chain because the surface area of the mesmerizing calming collars for dogs is greater. If you’re not sure about this, try it on yourself and compare it to the choke chain. You can try it on your arm or your leg. You don't have to try it on your neck. Although they may cause less pressure around the neck than a choke chain they do still increase pressure so they can still lead to all of the same issues that a flat collar and even a choke chain causes.
The next step in training dogs with a head collar is to train them that when they reach the end of the leash they are going nowhere. That means the owner must hold perfectly still and avoid taking a step or even moving the leash-holding hand. Once the dog figures out that pulling harder does not work and instead steps back or turns to the owner such that the leash is hanging loose, then the owner can resume walking. Better yet, the owner can reward the dog with a treat so that dog comes all the way back to her and then they can resume walking forward. It's important that the dog learn that a tight leash and the associated pressure created means she should stop. If the dog is not taught this and tends to act impulsively, she may dart out after a cat or other object and hit the end of the leash with some speed. This type of accident could potentially cause neck pain or injury. Even in the emergency situation, if the owner is paying attention, they can prevent neck wrenching if they gradually tighten the leash rather than letting the dog dart forward on a loose leash so that she suddenly hits the end.
