You're dog will jump for joy every time it sees the Scottish Terrier collar & leash. It's walk time! Each Scotty collar & leash has a quick release fastener, making them easy to take on and off even the most excited pup. They feature repeating images of your favorite dog breed and are made from durable nylon, so they can be machine-washed. The collars are contoured to fit the curve of your pet's neck for the best possible comfort. The Scottish Terrier collar fits dogs with necks that are 10 to 16 inches. The leash measures 4 feet.
