Just moved back from Puerto Rico where we adopted an adorable "sato", ie mutt (beagle/spaniel type mix). She was used to hot days and warm nights so imagine her surprise to find herself in Chicago heading into winter without the necessary fur. This sweater gives her great coverage; she is disproportionally long and it just about hits her hips (small size). This isn't great for windy conditions but lets her snuggle into a nap and takes the edge off while she's romping around the back yard or dog park. Recommend for dogs that like the total wrap around the body.
