Patented dog ear stand up support: Helps train your dog's ears to stand upright. This ear training tool is designed to support proper ear posture without causing harm. Includes left and right brackets, a base, and 2 adhesive tapes. Easy to use: Clean the dog's ear thoroughly before application. Gently place the clamp starting from the bottom, inserting a small piece of cotton between the ear and the clamp to provide cushioning. Do not wrap the tape too tightly. Adjustable design: Features an insertable structure with adjustable inner width from 3.1 to 4.7 inches, suitable for most dog breeds with naturally erect ears. Made from high-elasticity material: Smooth edges prevent irritation or injury. Durable and flexible construction provides consistent support for developing ear cartilage. Note: This product is intended for use with dog breeds that have naturally standing ears and may require additional support during development. The ideal age to begin use is around 3 months. Results typically appear within 1–2 months. Check your dog's ears every 3 days. If the ears remain upright without support, discontinue use. If not, reapply the device as needed.
