- Durable three-layer construction: outer jute, middle soft padding, and inner cotton layer with a protective inner lining that guards your arm from dog teeth. - Professional training design: specifically made for dog training activities such as puppy obedience, police K9 work, tug of war, agility, and circle sports. Helps reduce boredom and anxiety and can prevent furniture chewing. - Comfortable and versatile: suitable for both professional trainers and beginners. Can be worn on either the right or left arm. Middle layer is thick and soft, and the sleeve is easy to put on and take off even over thick clothing. - Safe bite space and fit: teething pillow provides ample room for the dog to bite while minimizing the risk of accidental bites. The bite cushion supports controlled tension during training sessions such as tug of war. - Practical use scenarios: use during in-home puppy bite inhibition sessions to teach bite control; in professional K9 or police training to practice controlled bite work; during tug of war or agility drills to channel energy and reinforce handling cues.
