Once the dog loves putting his nose into the head halter and the owner puts it on, the owner may need to engage the dog in fun behaviors to distract him from the funny object on his face until the dog gets used to it.
The cool cool 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, cool cool collars for dogss produce less pressure on the neck when jerked hard compared to the choke chain because the surface area of the cool cool 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.
