Our original design-a friend for your best friend! Hugglehounds Knotties are the original knotted, plush dog toy! Knotties are the most durable plush dog toys available for dogs and puppies. All Knotties are made with exclusive Tuffut Technology, a durable three-layer lining on the inside that stays soft and cuddly on the outside.As they are sized way down for our smaller doggos, Wee toys do not feature Tuffut Technology, and contain only one squeaker.
