Ten to fourteen years. That's roughly how long a greyhound will share your couch, your car, and quite possibly your bed. But here's the catch: for a dog built almost entirely of muscle, bone, and not much else, winter can feel a lot longer than it looks on the calendar. I'm a greyhound parent myself, to a very opinionated hound named Pepper, and I can tell you she has never once "toughed out" a cold morning without a fair bit of drama first. Let's get to the coat of the matter!

Sighthounds are famous for their speed. What they're not built for is insulation. Greyhounds, whippets, and Italian greyhounds all share the same lean architecture: minimal body fat, a paper-thin coat, and skin that offers almost no barrier against the cold. It's a brilliant setup for a 60 km/h sprint. It's a rough deal on a frosty morning.

Built for Speed

A greyhound's body fat sits well below that of most other breeds, and their coat has no insulating undercoat at all. That combination is exactly what makes them so aerodynamic on the track. It's also exactly why a chilly Melbourne morning hits them harder than it hits, say, a Labrador. The Greyhound Adoption Program in Victoria puts it plainly: greyhounds have relatively thin skin and very little body fat, which is great for cooling down after a run, but leaves them genuinely susceptible to cold weather.¹ This isn't a quirky preference. It's basic physiology.

Whippets and Italian greyhounds share the same build in miniature, and Iggies in particular tend to feel the cold even more acutely given their smaller frame. If you've ever seen a whippet do the classic "curled-up armadillo" pose on a cold couch, that's not a personality trait. That's thermoregulation in action.

Signs of Cold

You don't need a thermometer to know your hound is cold. Watch for shivering, a tucked tail, reluctance to walk further than the letterbox, or a sudden urge to burrow under every blanket in the house. Some hounds will lift a paw off cold ground repeatedly, almost like they're testing the temperature before committing. If you notice any of this on a walk, it's time to head home and warm up, not push on for one more block.

None of this means your dog is fragile or unwell. It simply means their comfort threshold for cold sits much lower than ours. A jumper isn't vanity here; it's a genuine tool for keeping a lean-bodied dog comfortable through the cooler months.

What to Look For

Not every coat on the market is doing your hound any favours. A few things actually matter:

• Full torso and belly coverage. Sighthounds have deep chests and very little padding underneath, so a coat that stops at the ribs leaves the most exposed part uncovered.
• A snug, not tight, fit. You should be able to slide two fingers under the strap comfortably. Loose coats slip and twist; overly tight ones restrict movement and rub.
• Water resistance for wet days. A soaked coat cools a dog down faster than no coat at all, so a water-resistant outer layer earns its keep in Australian winter drizzle.
• Layering for genuinely cold snaps. On the coldest mornings, a lightweight base layer under a heavier outdoor coat gives you flexibility without overheating your hound indoors.

Once you've sorted the coat, don't forget what's underneath it. A well-fitted martingale collar still matters through winter, since a bulky coat can make it easier for a nervous or cold hound to back out of a standard collar on a walk. Safety and warmth work together, not against each other.

Breed by Breed

Cold tolerance isn't identical across every sighthound, even though the underlying biology is similar. Our Greyhound pet profile goes into the breed's build in more depth, and it's worth a read if you're new to hound life. Whippets, being smaller and often a touch more sensitive to temperature swings, are covered in our Whippet pet profile, and if you're shopping for a snug winter fit, our whippet collar range is designed around their narrower proportions.

Italian greyhounds deserve a special mention here. They're often the first to shiver and the last to warm back up, and their delicate frame means winter care is less optional than it is for their larger cousins. Have a look at our Italian Greyhound pet profile for more on their needs, and browse our Italian greyhound collars if you're kitting one out for the season.

Health Notes

Cold sensitivity in sighthounds ties into broader physical traits worth knowing about as a pet parent. Their low body fat and thin skin mean they're more prone to feeling sore on hard, cold surfaces, and some hounds develop stiffness in their joints during winter, much like people do. Keeping your hound warm, active within reason, and comfortable on soft bedding goes a long way. If you ever notice persistent stiffness, reluctance to move, or anything that seems out of character, a chat with your vet is always the sensible next step.

The Bottom Line

So, do greyhounds need coats in winter? In most parts of Australia, yes, particularly on cold mornings, at night, and for smaller or older hounds. It's not about babying your dog. It's about working with their biology rather than against it. Pepper certainly doesn't complain when her coat goes on. If anything, she sits by the door and waits for it, tail wagging, like she's the one who trained me.
