As the air temps cool and our time on the water remains the same; I see our CBR shiver a bit more. When active- fetching bumpers etc all is fine, but wet and less active she does not look very comfortable. So, do you provide your dog w/ a vest or something else? Any recommendations ? I sure would like to cast and blast this fall- duck by dawn and rainbows all day, but would like to make sure my dog is safe.
