Now you and your dog will walk in harmony with your new Martingale collar and velvet leash from Wiggles, Wags & Whiskers. This "humane" passive-restraint collar is designed with 2 loops, which is why it is often called a Double Loop collar. It allows you to easily walk your dog without the dog choking. It comes highly recommended by vets and trainers. This beautiful pink floral 1 in. collar fits up to size 18 in. neck. Matching pink velvet leash. You will also receive 3 durable Kong toys, which your dog will enjoy for many hours after you've walked!
