Greyhounds And Muzzles: Everything You Need To Know

It’s common to see greyhounds with muzzles while on a walk. These muzzles do perform a valuable function when you have such a large dog. Feeling put off by a muzzle is normal because you think it’s restricting your greyhound.

Muzzles may also make people believe that your dog is dangerous. However, that’s not the case; muzzles are an excellent idea for many other reasons. 

Why Should Greyhounds Wear Muzzles?

Greyhounds still of racing age should wear a muzzle to prevent them from getting too carried away with their chase instinct. Although they aren’t aggressive with people, they may feel too excited after a race and take playing too far.

Muzzles are a great way to minimize the licking and biting of stitches or wounds after an accident or veterinary treatment. They’re an alternative to the cone collars you see other dogs wearing. 


To keep that slim physique, greyhounds have to have a particular diet. While you’re out on a walk, they might be tempted by junk food, trash, or items they absolutely shouldn’t eat that they find scattered around on the floor.

A muzzle prevents them from eating things that they shouldn’t. 


As with most dogs, greyhounds probably won’t like the vet. Their anxiety in the veterinary surgery may cause them to act differently. Your vet will find a muzzle beneficial to conduct a thorough examination without fearing being bitten. 


While you’re out in the park, your greyhound is likely to meet many other dog breeds – many much smaller than themselves.

If your greyhound wants to play, a muzzle ensures they don’t get too carried away with other dogs (especially small ones) and gives other owners peace of mind. 


Muzzles can help significantly with training. When you first take a greyhound into your home, they may not be aware of home etiquette.

They’ll have likely lived in a kennel for their entire lives until this point if they’re a retired racer. In this former life, certain behaviors will have been acceptable, which you might need to stop.

Muzzling your dog during training will help develop that respect between you and them and allow them to see you as the pack’s alpha. 


Introducing your greyhound to other pets in the household could be tricky. Although greyhounds are generally friendly with other dogs, you could have initial teething problems if you have a small dog or cat.

Based on their instincts, your greyhound will likely see them as prey rather than their family. Having a muzzle safeguards against accidents if your greyhound feels the need to chase your cat. 

Do Greyhounds Have to Wear Muzzles in Public?

Your greyhound doesn’t have to wear a muzzle in public if you don’t want them to, especially if they’re retired from racing.

The law changed in the US and UK in 2019 so that greyhounds retired from racing can walk without a muzzle as long as they’re leashed.

There are some exceptions to this rule, though, depending on the country you’re living in, so it’s best to check out the specific laws before you go ahead. 

If you intend to let your dog off the leash, it’s best to keep them wearing a muzzle. This is because off-leash areas tend to be places where your greyhound might chase prey animals.

While outdoors, their chase instinct is intensified, and something as small as a blowing leaf or stray piece of trash will activate their need to catch something. The last thing you need is to have your greyhound being able to catch rabbits while you’re on a walk. 

A muzzle not only physically stops them from catching prey but becomes a sort of mental reminder for them that chase behavior isn’t acceptable and keeps them mentally restrained, even if they’re off the leash. 

Do Retired Racing Greyhounds Need To Wear Muzzles?

Retired greyhounds are known to be calm, affectionate, and sweet-natured dogs who aren’t prone to aggression.

Although they are large dogs and might seem intimidating to some people, they’re mostly gentle giants. Unless your dog has a known behavioral issue, you shouldn’t worry about them biting anyone. 

Do Racing Greyhounds Have To Wear Muzzles?

If you still have an active racing greyhound, it is safer to keep them muzzled during the racing period, and it’s compulsory to have them muzzled during the race itself.

This is because, when they race, their bodies are pumped with adrenaline to keep them active and able to chase down prey. 

A muzzle helps protect the other dogs in the race and stops fights from breaking out if dogs don’t get along. As greyhounds are pack animals, they run as a unit to chase down the prey, and the muzzle allows them to focus on the task rather than each other. 

Immediately after a race, you might find that the greyhound is more mentally stimulated and excited, potentially making them more aggressive if someone approaches them. 


Muzzle-wearing is mostly about practicality for dogs off the race track. However, surprisingly, a muzzle also helps the judges of the race. All greyhounds race-wearing muzzles.

It’s compulsory, not just to protect the other dogs, but because it’s difficult to see, even on a camera, whose nose is first across the line. 

Greyhounds run in a pack, so there’s never usually a massive difference between the first and last dog in the race as there would be with horses. Specialist greyhound muzzles allow the judge to see where their nose ends and help the judge determine the winner. 

Are Muzzles Cruel?

No, you can buy specialist greyhound muzzles that are padded around their nose, equipped explicitly for comfortably fitting their long snout, and are lightweight, so your greyhound may not even feel them on there. 

Greyhounds that are retired from racing will also be used to wearing a muzzle, so they won’t see you as the bad guy.

When racing, their owners would have put a muzzle on them until they’d calmed down from the adrenaline of the race to keep other dogs and owners safe.

Retired greyhounds may even see the muzzle as comforting, as it’s something they’re used to, in contrast to the new environment that they’re introduced to when they come into your home. 

Why Did Greyhounds Have To Wear Muzzles In Australia?

In Australia, a law in 1927 stated that all greyhounds must wear a muzzle when in public even if they’re retired from racing. This was to protect other dogs and people they work with on the track.

It was thought that a greyhound’s chase instinct couldn’t be deactivated, and they would always have the desire to catch and kill. Unfortunately, this law is still in place. 

However, greyhounds tend to retire at around two years old and make fantastic pets afterward. The ‘pet lifestyle’ is new for them, but they are pretty adaptable.

When they’re in your home, greyhounds are incredibly affectionate and lazy. While they maintain their chase instinct when off the leash in wide-open spaces, they’re not ordinarily aggressive in the home or outside on a leash at all. 

This rule changed, however in 2019 when pet greyhounds no longer need to be muzzled as long as they are leashed.


Racing greyhounds must wear muzzles while they’re on track and immediately afterward. However, if you have a retired greyhound, you can be confident that your dog will be safe to be around most of the time without a muzzle.

It’s still recommended to pop on a muzzle if you plan to let them off the leash in the park to protect rabbits, squirrels, cats, and other smaller dogs from their natural chase instinct.
