Our Redbone Coonhound pulls really hard when we walk her. Sometimes she'll pull so hard it makes your arm hurt! A salesperson at Petsmart let us try out this head collar because it's supposed to keep the dog from pulling. We hated this collar. The dog hated it too. She shook her head the entire time it was on, way worse than her pulling us with a leash. It was embarrassing and very uncomfortable. Maybe she just needed some time to adjust, but I wouldn't recommend this product.
