Patented dog ear support: Helps train dogs' 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 before application. Gently place the clamp starting from the base of the ear. Insert 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 insert-style structure with adjustable inner width from 3.1 to 4.7 inches, suitable for most dog breeds. Made with high-elasticity material: Constructed from high-quality flexible material with smooth edges to prevent irritation. Durable and gentle on the ear while providing reliable support. Note: This product is intended for use with puppies that have naturally erect ears but require additional support during development. The ideal age to begin use is around 3 months. Results typically appear within 1–2 months. Check the ears every 3 days. If the ears remain upright without support, discontinue use. If not, reapply the support as needed.
