Colorful design M size harness A Finnish brand - Brand: Ratia - Design: Colorful design - Size: M size - Neck: 11.8 inches (approx. 30cm) - Chest: 14.9-21.6 inches (approx. 37.8-54.9 cm) Thank you for viewing. I tried it a few times near my house, but it didn't fit my dog... It's cute, so I'm selling it. I haven't used it for long walks, etc. The Amazon image is a quote of the S size, but the M size is the actual item! It has been stored at home. Please refrain from purchasing if you are concerned.
