Why Some Greyhounds (And Other Dogs) Need to Wear Muzzles: A Guide for Curious Humans

Muzzles are often misunderstood. While they can look intimidating, they're simply a tool—like a leash or a harness—used to keep dogs safe and comfortable in the world around them. For many greyhounds, wearing a muzzle isn't just common—it's often required. But why?

1. Greyhound Racing History & Legislation

Greyhounds come from a unique background. Many are rescued ex-racing dogs, and in places like Victoria, it's legally required that greyhounds wear a muzzle in public—unless they are registered with the council and are officially exempted. This is not because they are aggressive, but because of their high prey drive, which is instinctive due to their breeding and training to chase small, fast-moving objects.

2. Muzzles Are a Safety Tool

Some dogs wear muzzles because they are still learning how to manage fear, anxiety, or overstimulation. A muzzle doesn't mean a dog is dangerous—it means their humans are taking extra care to prevent uncomfortable or reactive situations. A dog might wear one when:

They're recovering from trauma or vet procedures
They're reactive in certain environments
They get overwhelmed by crowds or unfamiliar dogs

3. Muzzles Reduce Risk, Not Love

Wearing a muzzle can prevent dogs from picking up dangerous items on walks (like picking up non food items from the ground), and reduce the chance of bites in stressful moments. Behaviourists often recommend muzzle training as a positive experience, helping dogs feel calm, confident, and safe while wearing them (source: RSPCA Knowledgebase).

"A muzzle doesn't mean a dog is aggressive—it means their guardian is responsible."

4. It's All About Training & Comfort

Modern muzzles, like our Plastic Greyhound Muzzles from Sighthound club, are designed to be worn for long periods without discomfort. When properly introduced with positive reinforcement, many dogs are perfectly happy to wear them, associating the muzzle with walks, treats, or fun outings.

Final Thoughts from Elle Fisk, dog trainer at Love Dogs

"Muzzles can make your dogs world larger, not smaller! The key is introducing and conditioning a muzzle positively, as it's just another piece of equipment. A muzzle is an extra layer of safety, and often allows both dog and owner to feel more comfortable when exploring or experiencing new things. When I see a dog in a muzzle, I know their owner is knowledgeable about their dog, and has taken the time to ensure they, and other dogs and humans are safe, or simply, that they have trained that skill! Great! Muzzled dogs deserve your understanding, and not your judgement".
