Review on 🐶 Herm. Sprenger Prong Collar Extra Links (3 Pack): 2.25 mm - Enhance Your Dog's Training Experience by Jennifer Mulder

Before using the Herm Sprenger spiked collar, my dog pulled on the leash while walking. I couldn't get him to stop pulling even after hiring a trainer and spending a lot of time following their instructions. He even drew when she went with him. He is an intelligent dog and learns many commands easily. With Herm Sprenger's collar, which unlike other collars with rounded ends, doesn't cut into the dog's neck, he immediately stopped pulling. I don't have to do anything but pull the leash a little. I can safely say that this tug will not harm the dog in any way! I suspect he just doesn't like the light feel it gives him as he doesn't complain or show any discomfort. He hated Halty's collar and freaked out trying to take it off until he could. I also tried a tourniquet, which also had no effect. There are many ways to achieve a goal, and some work better than others. This is not the case for all.
