2 Hounds Design makes harnesses, collars, and leashes for dogs. The unique name comes from the founder’s two retired racing Greyhounds that needed special martingale collars. She decided to make her own, and the rest is history. Not all materials for each product are sourced in the USA, but most are, and assembly happens here as well. Check out their freedom no-pull harness in particular – it’s very popular and a great option for pups who pull.
