The prong collar is a simple and effective tool for teaching your dog to respond appropriately to pressure on the leash, and Herm Sprenger prong collars are the gold standard of quality.
When properly used, prong collars protect the crucial areas of the dog's neck by distributing pressure evenly around the neck, and reducing the over amount of pressure needed.
As always, we recommend proper education to learn how to use the prong collar properly.
