The sporn non pulling mesh harness offers total control, style and comfort for every dog. The elastic webbing stretches laterally with dog's natural movements, while the unique mesh design provides maximum comfort. Available in black color. Colors apply to the trim around the neck; mesh, attaching straps and sleeves are always black. All materials and components are made of the highest quality nylon and nickel-plated hardware to reduce weathering. Comes in medium size. Fits cocker spaniels, golden retrievers, border collies and like breeds. Fits 12-inch to 17-inch neck size. Place the harness over the dog's head so the mesh covering is below the dog's neck in front, the nylon straps are on either side of his/her head, and the metal O-ring sits just above the dog's shoulders on his/her back. Guide the dog's legs through the sherpa covered loops. Adjust the nylon straps for a comfortable fit. When pulling occurs, the padded sherpa sleeves will tighten and apply gentle pressure under the dog's front legs. Adjust the sliding cord lock for a snug (not tight) fit. Attach the dog's lead to the O-ring and enjoy your walk. Measures 8-inch length by 4-4/5-inch width by 2-inch height.
