Turtleneck Fleece Dog Onesie With Loose Fit for Whippets and Italian Greyhounds

This fleece dog onesie features a high turtleneck collar and a relaxed four-legged cut designed specifically for the long back, deep chest, and slim proportions of Whippets and Italian Greyhounds. Available in six sizes from XS with a chest of 11.0–12.6 in (27.9–32.0 cm) up to XXL with a chest of 21.7–24.4 in (55.1–62.0 cm). The loose fit gives your dog full freedom of movement across all four limbs without restriction, and the turtleneck covers the neck completely — a meaningful detail for breeds that lose heat quickly through an uncovered neck. Lightweight, soft, and warm enough for autumn, winter, and spring use.

Why Whippet and Greyhound Owners Choose This Onesie

• High turtleneck collar: Fully covers the neck — a particularly important detail for thin-coated sighthound breeds who lose body heat rapidly through an exposed neck during cold-weather walks and outdoor rest.
• Relaxed four-legged fit: The loose cut allows natural, unrestricted movement across all four limbs — your dog can walk, run, and stretch without the onesie pulling or pinching.
• Fleece construction: Soft, warm fleece provides comfortable insulation across autumn, winter, and spring without the bulk of a padded coat — suitable for both outdoor wear and all-day indoor use.
• Tailored sighthound proportions: Cut for a long back, deep chest, and slim waist — owners confirm it fits like a custom-made garment when the correct size is selected using chest and back measurements.
• Six sizes XS–XXL: Chest range from 11.0 in (27.9 cm) up to 24.4 in (62.0 cm) — covers the full size range from small Italian Greyhounds through to larger Whippets.
• Lightweight and durable: The fleece holds its shape and softness through regular cold-water machine washing — straightforward to maintain throughout a full season of daily wear.

Made for Sighthounds Across All but the Coldest Conditions

This Whippet fleece jumpsuit suits Italian Greyhounds, Whippets, Greyhounds, and similar lean breeds looking for a warm, comfortable everyday layer across the cooler months. Use it as an indoor fleece onesie for dogs who feel the cold at home, an autumn and spring walking layer for milder outdoor conditions, or a base layer worn under a waterproof coat in wetter or colder weather. The turtleneck and four-legged design make it noticeably warmer than a standard dog jumper or vest — and the relaxed fit means dogs accept and move in it comfortably from the first wear. Customer service recommends sizing up if your dog's measurements fall between sizes. Available in purple and brown.
