Size: The Koogal dog raincoat is tailored for medium and large breeds. Measure your dog s neck, chest and back length, then check weight before choosing a size the chart matches Golden Retrievers, Labradors, Rottweilers, large hounds and Aussie-Husky mixes. Material: a tough outer shell blocks rain completely while the inner layer stays soft and quiet for all-day comfort. Function: two rear-leg straps keep the coat centered and prevent wind lift. Convenience: quick-fit sliders adjust chest and back length in seconds, a zippered back pocket stows treats or keys, and a harness-ready leash portal means no awkward re-strapping. Safety: reflective piping along the edges and a light loop give 360° night visibility. Machine-wash cold, hang dry the fabric resists mud and odor so one rinse restores the shine.
