Dog Winter Onesie Fleece Lined Waterproof Whippet Greyhound Sizes 1–10 Leash Opening Windproof Suit | Koossa

Fleece Lined Waterproof Dog Winter Onesie for Whippets and Greyhounds

This dog winter onesie combines a polyester and nylon waterproof windproof outer with a fleece inner lining, tailored specifically for the lean, deep-chested build of Whippets and Italian Greyhounds. Available in ten sizes from size 1 with a chest of 13.8–15.4 in (35.1–39.1 cm) up to size 10 with a chest of 28.0–29.5 in (71.1–74.9 cm). A built-in leash opening allows lead attachment without removing the suit, and the full-body coverage keeps your dog warm and dry in cold, wet, and snowy conditions. Owners report comfortable walks at temperatures as low as -11°F (-24°C) — a genuine cold-weather suit for breeds that feel the cold most.

Why Whippet and Greyhound Owners Choose This Onesie

• Waterproof and windproof outer: Polyester and nylon shell blocks wind and repels rain and snow across the full body — reliable protection in harsh winter conditions without soaking through.
• Fleece inner lining: Soft fleece against the skin retains body heat effectively — particularly important for thin-coated sighthound breeds who have minimal natural insulation.
• Full-body tailored cut: The onesie covers chest, back, and belly in a cut shaped for sighthound proportions — no gaping at the chest or bunching at the waist that standard dog coats produce on these breeds.
• Built-in leash opening: A dedicated opening allows lead attachment to a harness underneath without removing the suit — practical for everyday walks without a dressing routine each time.
• Ten sizes 1–10: Chest range from 13.8 in (35.1 cm) up to 29.5 in (74.9 cm) — covers Italian Greyhounds at the smaller end through to full-size Greyhounds and large Whippets.
• Removable belly panel: The belly section can be removed — useful for male dogs and for adjusting coverage based on temperature and conditions.

Made for Sighthounds in Serious Cold Weather

This Whippet winter suit suits Italian Greyhounds, Whippets, Greyhounds, Lurchers, and similar lean-bodied breeds who struggle to maintain body temperature in cold and wet conditions. Use it as a full-body dog winter onesie for outdoor walks in snow and frost, a windproof dog suit for exposed open-field runs, or a daily cold-weather layer for dogs who live in climates with harsh winters. The ten-size range and chest-based sizing means you can find a precise fit rather than approximating with a standard S–XL system — particularly valuable for sighthound owners who know how difficult standard sizing is for their breed. Measure chest circumference and back length carefully before selecting.
