This is great protection against cold water! I live in Colorado- far from the warmer waters !! This allows my Portuguese Water Dog to swim comfortably early in the season
Osa loves the water and doesn't know when to stop playing when she is cold. This give her extra comfort and makes me feel better. Keeps her warm. It fits under her PFD nicely. The color is adorable on her as well.
Was concerned that an XS would be too small, especially since it has sleeves. But our dog’s Ruffwear harness and raincoat are XS so we ordered accordingly. The undercoat and PFD both fit, even on a short-legged and slightly chonky dog!
Great coat!
This will be absolutely perfect for our snake river trip this year! The water does get cold even when you’re in the sun and this little wet suit will be great insulation under Tuesday’s float coat!
