Perfect for medium to large dogs! The Gentle Leader for excellent stability ■ Color: Red ■ Size: L (※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 "instinctual impulse to move in the opposite direction of the pulling force" to gently control pulling and jumping. • It is designed to be less stressful for dogs, 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. • Also, unlike traditional collars, it is designed to have 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. This product is a favorite among owners and trainers. Attach it so that it forms a "V" shape when viewed from the side. Secure the neck strap at the highest point of the neck. Make it snug on the neck, just enough to fit one finger. Loosen the nose loop so that it allows the dog's nose to move freely from the eyes to the fleshy part of the nose.
