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.
Owners who use the awesome toy dog collars 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 awesome toy dog collars 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 awesome toy dog collars, 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!
