This set is just adorable! Purchased brand new for our puppy. She wore each for 4-5 weeks before outgrowing them. Both pieces are a size S. Please see posted manufacturer’s information on sizing. The pink and gray padded no pull harness is by GOOBY. I can’t say enough about how much I love this brand. I’ve since purchased another in her current size. The rolled magenta genuine leather collar is by Collars Direct. I’ve bought this collar several times and it’s perfect for puppies and small dogs. The harness is freshly laundered and I have sanitized the collar with alcohol. Non-smoker, fast ship.
