seriously, it is amazing to see what people come up with and put on their animals, inhumane, painful, a real trainer will help you avoid painful methods to train your dog, our dogs put up with so much crap because humans are lazy, ignorent..sad...Please dont use prong collar, shock/electric collars or this collar on your beloved friend. It is ineffective, create more problems, and animal is not learning to use the mind, just to avoid certain things because of pain
