Flower Pattern Harness and Lead Set, All-Season Purchased for 2480 yen I bought this because it's very cute, but it didn't fit because I didn't measure properly. My dog is a Pomeranian-Chihuahua mix and weighs 4.5 kg, with a chest width of 42 cm, so I think it will fit if you measure properly before purchasing. I only tried it on once to see if it fit. - Design: Flower pattern harness and lead set - Size: M - Length: 8 cm - Chest Width: 39 cm - Features: Short type, all-season Thank you for looking.
