How should Italian Greyhound & Whippet clothing fit?

Well-fitting clothing should stay stable throughout your dog's day, not just during the first fitting. Your Italian Greyhound or Whippet should be able to walk, run, stretch and play without the garment twisting, slipping or gradually changing position. If the fit gets worse after a few weeks of wear, it wasn't really a good fit to begin with.

When Lola was a puppy, I thought buying dog clothes was simple. If the chest, neck and back measurements matched the size chart, the fit should be right.

It turned out to be much more complicated than that.

Some jumpers looked perfect the day they arrived. A few weeks later, the neckline had relaxed, the sleeves had crept lower and the whole garment slowly started sliding backwards. Nothing dramatic happened overnight. The fit simply became a little worse with every walk and every wash.

That was the moment I stopped thinking about fit as a measurement problem and started thinking about it as a pattern-making problem.

Today, when I'm developing a new pattern, I don't ask whether it fits on day one. I ask whether it will still fit after fifty walks. Because good fit isn't just about measurements. It's about how a garment behaves over time, how it moves with the dog and whether it continues doing its job long after the excitement of opening the parcel has worn off.

In this guide, I'll show you what good fit actually looks like, the most common signs that something isn't working, and the principles I use when designing clothing specifically for Italian Greyhounds and Whippets.

How should clothing actually fit an Italian Greyhound or Whippet?

A well-fitting garment should allow your Italian Greyhound or Whippet to move exactly as they would without wearing clothes. They should be able to walk, run, stretch, curl up, jump onto the sofa, toilet and play without the clothing pulling, twisting or getting in the way.

The biggest misconception is that comfort means buying clothing that's slightly loose. In reality, good fit is about stability, not tightness. A garment should sit close enough to the body to stay in place as your dog moves, while still allowing complete freedom through the shoulders, chest and hips.

One of the first things I learnt while designing clothes for Lola was that the real fit test doesn't happen when you first put the garment on. It happens after twenty minutes of walking, running and playing. If the neckline starts slipping backwards, the sleeves creep down the legs or the garment twists around the body, it isn't fitting as well as it should.

A well-fitting garment should:

• Stay centred on the body while your dog moves.

• Not slide down the dog's body over time.

• Allow full shoulder movement without pulling across the chest.

• Keep sleeves above the wrists throughout the walk.

• Finish at the base of the tail without extending much beyond it.

• Stay in the same position after running, stretching and playing.

Good clothing shouldn't ask your dog to adapt to it. It should quietly adapt to your dog's movement instead. In my experience, that's the difference between clothing a dog simply tolerates and clothing they almost forget they're wearing.

Why do so many dog clothes fit Italian Greyhounds and Whippets so badly?

Italian Greyhounds and Whippets aren't simply smaller versions of other dogs. Their long necks, deep chests, narrow waists and exceptional range of shoulder movement make them one of the most challenging body shapes to design clothing for.

Many garments appear to fit when the dog is standing still but start sliding, twisting or pulling as soon as they begin moving. That's because clothing isn't just following the dog's measurements, it's following the dog's movement.

This is particularly important for sighthounds. Their powerful galloping stride, flexible spine and athletic build place much greater demands on clothing than slower-moving breeds. A pattern that works perfectly well on a Labrador or Cockapoo may become unstable on a Whippet simply because their proportions and movement are completely different.

The good news is that good fit isn't about making clothing tighter. It's about designing it to stay stable while allowing complete freedom of movement.

Common signs a garment wasn't designed for a sighthound

• The neckline gradually slips down the shoulders.

• Sleeves become longer as the dog moves.

• The garment twists around the chest or waist.

• The dog catches an elbow inside the armhole while running.

• The clothing looks neat standing still but shifts significantly during a walk.

How can I tell if my Italian Greyhound's or Whippet's clothes are too small or too big?

The easiest way to judge fit isn't by looking at the clothing. It's by watching your dog’s behaviour. If your dog suddenly walks differently, hesitates to run or constantly needs their clothes adjusting, the fit is worth questioning.

A well-fitting garment should look almost the same after twenty minutes of walking as it did when you first put it on. If it's constantly shifting, sliding or twisting, it's often the pattern rather than the size that's causing the problem.

Should dog clothes be tight or loose on an Italian Greyhound or Whippet?

Neither. Well-fitting clothing should feel stable, not tight or loose.

Many owners instinctively size up because looser clothing feels more comfortable to us as humans. For Italian Greyhounds and Whippets, however, extra fabric often creates more problems than it solves. As your dog walks and runs, loose clothing can shift around the body, bunch behind the elbows and gradually slide out of position.

At the other extreme, clothing that's too tight can restrict shoulder movement, rub against the skin and make your dog reluctant to move naturally.

The goal is to find the balance between the two.

A well-fitting garment should:

• Sit close enough to stay in place.

• Allow full shoulder and leg movement.

• Stay centred while your dog walks and runs.

• Leave enough room for two fingers comfortably under the chest.

• Never require regular adjustment during a walk.

If you find yourself constantly rolling sleeves up, pulling the neckline back into place or straightening the garment, it's probably too loose. If your dog walks stiffly, hesitates to run or develops rubbing around the neck or armpits, it may be too tight.

A note from the studio:

One thing I've learnt from developing clothing is that fabrics naturally relax over time. A garment that's already slightly loose when it's new will usually become even less stable after repeated wear and washing. I always judge fit by asking how it will behave after months of real walks, not just the first fitting.

Ultimately, good clothing shouldn't simply fit your dog's measurements. It should stay stable while allowing them to move exactly as nature intended.

Figure 1. A well-designed armhole stays smooth behind the elbow, allowing full shoulder movement without excess fabric bunching.

Why does my Italian Greyhound or Whippet hate wearing clothes?

Not every dog that dislikes wearing clothes actually dislikes clothing. Some simply aren't used to the sensation. Others have had a negative experience while getting dressed. And quite often, the problem isn't the dog at all. It's clothing that doesn't fit properly.

A well-fitting garment should become something your dog almost forgets they're wearing. If your dog freezes, constantly tries to rub the clothing off or moves differently every time they're dressed, it's worth questioning the fit before assuming they simply "hate clothes".

Common reasons dogs dislike clothing

• They're unfamiliar with wearing clothes.

• The garment restricts their movement.

• Sleeves or necklines rub against the skin.

• The clothing shifts or twists while they walk.

• They've previously had a stressful experience getting dressed.

The good news is that many of these problems can be improved.

If your dog has never worn clothes before, introduce them gradually. Let them investigate the garment, reward them for putting their head through the neckline and build confidence in small steps. Starting with a simple vest or sleeveless jacket is often easier than introducing a fully sleeved onesie straight away.

Remember, the goal isn't to teach your dog to tolerate clothing. It's to choose clothing comfortable enough that they hardly notice it's there.

Should sleeves reach my Italian Greyhound's or Whippet's paws?

No. For most Italian Greyhounds and Whippets, sleeves should finish above the wrists when your dog is standing still.

When I say it, this often surprises owners, but it's intentional. As your dog walks, runs and stretches, the garment naturally shifts slightly on the body. Sleeves that already reach the wrists while standing often become too long once the dog starts moving, increasing the risk of bunching or interfering with their stride.

Italian Greyhounds and Whippets have an exceptionally long range of motion through their shoulders and forelimbs. During a gallop, their front legs extend far in front of the body before folding tightly back underneath the chest. Any excess fabric around the lower leg has the potential to move into that space, particularly after the garment has relaxed through wear.

A good sleeve should:

• Finish above the wrist.

• Stay clear of the paw throughout the walk.

• Allow unrestricted shoulder and elbow movement.

• Stay in position without needing to be rolled up.

A sleeve that's a little shorter rarely affects warmth. A sleeve that's a little too long can completely change how a garment behaves once your dog starts moving. For athletic breeds like Italian Greyhounds and Whippets, freedom of movement should always take priority.

Figure 2. Correct sleeve length finishes above the wrist so the paw stays clear during movement.

Why do some dog clothes sag, twist or fall down when dogs run?

If your dog's clothing starts twisting, sagging or slipping out of place, it's usually because the garment has become unstable. That doesn't necessarily mean it's the wrong size. It could be the pattern, the fabric, or simply how the garment behaves after repeated wear and washing.

Unlike human clothing, dog clothing is constantly being pulled in different directions. Italian Greyhounds and Whippets sprint, wrestle, roll on the ground and stretch dramatically as they move. Over time, those forces can expose weaknesses in both the pattern and the construction. One of the biggest problems I see is garments that fit beautifully when they're new but gradually become less stable as the fabric relaxes.

In my experience, the neckline is often the most important seam in the entire garment. Once it begins to stretch and lose its shape, the whole garment gradually starts moving down the body. Sleeves become longer, the chest drops lower and the clothing is much more likely to twist during movement.

A note from the studio:

I never judge a new pattern after the first fitting. I judge it after weeks of walks, washing and zoomies. That's when you discover whether a garment simply fits well on day one, or whether it continues fitting well after months of real life.

A well-designed garment shouldn't just fit beautifully when it's new. It should continue behaving the same way after dozens of walks and repeated washing. That's often the difference between clothing that looks good and clothing that's genuinely built to last.

Can my Italian Greyhound or Whippet wear clothes with a harness?

Yes. In most cases, clothing and a harness can be worn together safely, provided both fit properly and are designed to work together. The best approach depends on the type of clothing.

For close-fitting garments such as jumpers, knitwear, vests and onesies, it's usually best to wear the harness over the clothing. These garments are designed to sit close to the body, and placing the harness on top helps keep everything securely in place while also reducing rubbing directly against your dog's skin.

Outerwear is different. A well-designed raincoat should leave enough room for the harness underneath and include a harness opening so you can attach the lead without exposing your dog's back to the weather. If your dog regularly wears a harness, it's worth choosing clothing that's been designed with that in mind rather than trying to make two incompatible pieces work together.

Does good fit change for puppies or older dogs?

The principles of good fit stay exactly the same, regardless of your dog's age. Puppies, adults and senior dogs should all be able to walk, run, stretch, lie down and toilet naturally without their clothing restricting movement or constantly shifting around the body.

What changes is how you choose clothing to suit their stage of life.

Puppies grow quickly and their proportions change as they mature. Instead of buying oversized clothing for them to "grow into", it's usually better to choose garments that fit well today and are made from fabrics with enough stretch to accommodate some growth. Clothing that's far too big often becomes unstable long before the puppy grows into it.

Older dogs often have different priorities. Arthritis, reduced mobility or recovering from surgery can make dressing more difficult, so clothing that's easy to put on and remove may be just as important as warmth. Look for garments that minimise twisting of the limbs during dressing and stay comfortably in place once they're on.

Whatever your dog's age, good clothing should support their movement rather than ask them to adapt to it.

What should I look for before buying clothes for my Italian Greyhound or Whippet?

Choosing the right clothing isn't just about picking the correct size. The best garments are designed to stay comfortable and stable throughout years of walks, zoomies and washes, not just during the first fitting. Whether you're comparing different brands or browsing our own Italian Greyhound and Whippet clothing collection, the same principles apply.

Before you buy, try to look beyond the product photos and ask how the garment will actually perform once your dog starts moving.

Here's the checklist I use when assessing any garment:

Is it designed specifically for sighthounds?

Italian Greyhounds and Whippets have very different proportions from most dog breeds, so clothing designed around generic dog shapes is less likely to fit well.

Does it allow completely natural movement?

Your dog should be able to walk, run, stretch, jump, curl up and toilet without changing the way they move.

Will it stay in place?

A well-fitting garment shouldn't constantly need pulling back into position or have sleeves rolled up during a walk.

Will it still fit after months of wear?

Look for quality construction and fabrics that recover their shape, rather than garments that are likely to become loose and unstable over time.

Does it suit your dog's lifestyle?

Think about how your dog actually spends their days. Do they wear a harness? Run off lead? Spend hours sleeping under blankets? The right clothing should work naturally with your routine, not against it.

At the end of the day, I always come back to one simple question:
Does this garment allow my dog to behave exactly as they would if they weren't wearing clothes?
If the answer is yes, you've probably found a garment that fits well.

Final thoughts

Italian Greyhounds and Whippets weren't built to stand still. They were built to move. That's why good clothing should never be judged on a hanger, on a mannequin or even on a dog posing for a photograph. The real test begins the moment they lower their head to sniff, launch into a sprint or curl up for a nap.

The best-fitting garment is the one your dog almost forgets they're wearing.

If you're looking for clothing designed around these same principles, you're welcome to explore our collection of clothing for Italian Greyhounds and Whippets. Every pattern is developed from the same philosophy you've just read about: garments that stay stable, move naturally with the dog and continue performing long after the first fitting.
