What Do Dog Collar Colours Mean?

Have you ever seen a dog in a bright yellow collar and wondered if it meant something? In some countries, especially the US and Australia, colour-coded collars and leads are used to signal things like nervousness, training, or special needs.

It’s not a formal system in the UK, but awareness is growing—and understanding what different colours might suggest can help avoid awkward encounters on your walks.

Of course, not every collar has a hidden meaning—sometimes it’s just about picking a colour you love. At Petiquette, we offer 28 leather shades to choose from, whether you’re sending a message or simply going for a favourite.

What Dog Collar Colours Can Mean on Walks

Red: “I need space”

Red is often chosen by owners whose dogs are reactive, anxious, recovering from vet treatment, or simply not keen on greetings. It’s not an official UK code, but many people recognise it from the US and Australia.

If you see a red collar or lead, it’s best to give space and ask before approaching.

Love red purely for style? You still can — just pair it with a clear “friendly” tag if you want to avoid mixed signals. We make a Red Leather Dog Collar if that’s your shade.

Yellow: nervous, in training, or newly rehomed

Yellow is often used for dogs who need more room — whether they’re nervous, in training, or fresh from rescue. Awareness of the “yellow dog” idea is growing in the UK thanks to various social campaigns.

If your dog wears yellow, a quick “he needs space, thanks” when someone approaches can help avoid awkward moments.

Like the look of yellow but don’t need the signal? Pair a yellow collar with a different-coloured lead so it feels more like a style choice than a message. Our Yellow Leather Dog Collar is a bright, cheerful option.

Green: usually friendly

Green is often read as “I’m happy to say hello.” It’s a welcoming colour abroad and is becoming more recognised in the UK.

That said, even the friendliest dogs don’t always want every greeting — watch their body language and check with the owner first.

If you just like green for its fresh, vibrant look, go for it. We offer a bright Lime Green Leather Dog Collar that’s perfect for a splash of colour.

Blue: working or in training

Blue is often seen on assistance dogs or those who shouldn’t be distracted — such as during training or focus work. In the UK, harnesses and vests usually signal this, but a blue collar or lead can still help get the message across.

If you spot a dog wearing blue, avoid eye contact, don’t pet, and let them pass without interruption.

If you simply like blue for its classic style, that’s fine — just be aware that some people may assume your dog has a working role. Our Blue Leather Dog Collar is a smart, versatile choice.

Orange: not keen on other dogs

Orange is sometimes used to show that a dog isn’t comfortable around other dogs. It’s a polite heads-up to give a little extra space, especially when passing on narrow paths or busy areas.

If your dog is working on this, pairing an orange collar with a quick verbal cue — “We’re training, could we have space?” — can help make things clear.

Prefer orange purely for its bold style? That works too. Our Orange Leather Dog Collar is bright, eye-catching, and handmade in the UK.

Purple: please don’t feed me

Purple is sometimes used to signal that a dog shouldn’t be given food — often because of allergies, a strict diet, or ongoing health issues. It’s a subtle but useful cue in cafés, pub gardens, and family gatherings.

If strangers often offer food to your dog, a purple collar can save you from having the same conversation multiple times.

Of course, you might simply love the colour. Our Purple Leather Dog Collar is rich, vibrant, and handmade in the UK.

---

White: deaf or visually impaired

White is often used for dogs who are deaf, blind, or partially sighted. It’s a gentle cue for others to approach calmly, speak to the owner first, and avoid sudden touches.

If your dog has sensory needs, a white collar or lead can make interactions smoother and less stressful.

Or you might simply like the clean, crisp look. Our White Leather Dog Collar is handmade in the UK and available in sizes to fit most dogs.

Ribbons instead of collars

You may also see coloured ribbons tied to a lead or collar. They serve the same purpose and are easy to swap depending on where you’re going. If you’re unsure what a ribbon means, ask—the owner will usually be happy to explain.

A quick UK note

There isn’t a formal colour-code system here. These meanings are better thought of as “useful hints,” especially in busier parks and towns. When in doubt, ask the owner and give space.

Choosing by colour (without sending mixed signals)

If you’re choosing a collar for style rather than a message, you can still enjoy any colour you like without causing confusion. If your dog doesn’t need to “say” anything on walks, a simple tag such as “friendly” or “in training” can help clarify things for anyone who knows the colour code.

And if you’ve found your perfect shade, match it all the way. A collar and lead in the same colour looks polished and intentional, so nobody’s left guessing whether it’s style or signal.

We make leather collars and leads in 28 colours, all handmade to order by neck size so you can choose the set that suits your dog best.
