Small dog anti-chewing item, yellow quack SS size. - Brand: OPPO - Product Name: quack - Size: SS - Color: Yellow - Purpose: Prevents chewing and licking Thank you for viewing. For dogs that bark, scavenge, or bite during grooming, how about this? Also useful for training and discipline. I bought this for grooming, but since I take my dog to a groomer, it has been stored at home since purchase.
