Perfect for medium to large dogs! The Gentle Leader with excellent stability ■ Color: Blue ■ Size: M (※See image) • This is a training tool that is attached to the muzzle (nose area). • By attaching the leash ring to the front, it utilizes the "instinctive impulse to move in the opposite direction of the pulling force" to gently control pulling and jumping. • It is designed to minimize stress on the dog, allowing them to eat and play with toys, making it popular. • By placing the center of gravity on the back of the neck, it avoids pressure on the throat, allowing for safe use. • Unlike traditional collars, it is designed to place the center of gravity on the back of the neck, so it won't press on the throat, causing the dog to feel suffocated or cough. It is a popular product among owners and trainers. Attach it so that it forms a "V" shape when viewed from the side. Fix the neck strap at the highest point of the neck. Make it fit snugly on the neck, just enough to allow one finger to fit. Loosen the nose loop so that the area from the dog's eyes to the fleshy part of the nose can move freely.
