It’s something many owners assume is covered until it isn’t.
Every week, lost dogs are shared across social media. Far too often, the same issue keeps coming up: no visible ID tag.
This post explains what the law actually says in the UK, what should (and shouldn’t) go on your dog’s tag, why microchips alone aren’t enough, and why choosing the right style of tag really does matter.
What Does UK Law Say About Dog ID Tags?
In the UK, the Control of Dogs Order 1992 makes it a legal requirement for dogs to wear identification when in a public place.
Your dog must wear a collar or tag that clearly displays:
- The owner’s surname
- The owner’s address (we recommend house number and postcode)
A contact phone number is not a legal requirement, but it is strongly advisable. In reality, it’s often the fastest way your dog gets home.
Failing to have visible ID can result in a fine, but more importantly, it can massively delay a lost dog being reunited with their family.
Why a Microchip Alone Isn’t Enough
Yes, dogs must be microchipped by law. But a microchip is not a GPS, and it doesn’t help unless someone:
- Finds your dog
- Knows to take them to a vet or rescue
- Has access to a working scanner
An ID tag allows a good samaritan to call you immediately. No vet visit required.
Dogs Trust also emphasise the importance of keeping ID and microchip details up to date, because thousands of stray dogs can’t be reunited each year when details are missing or outdated. Microchipping advice from Dogs Trust.
A Real-Life Reminder (Why This Matters)
A couple of years ago, Bear wandered out of the garden on a warm summer evening. The door was open, he was relaxed, and I didn’t think much of it.
Not long after, I got a phone call:
“Alright mate, I’ve got a Labrador going through our bins.”
If Bear hadn’t been wearing an ID tag, that situation could have ended very differently. He could have travelled further, crossed a road, or ended up injured before anyone knew where he was.
That tag got him home quickly and safely.
What Should You Put on a Dog ID Tag?
One common mistake is treating the tag like a name badge.
We don’t recommend putting your dog’s name on their ID tag.
Here’s why:
- It gives strangers unnecessary familiarity with your dog
- It doesn’t help someone contact you any faster
- The focus should be on returning your dog, not engaging with them
Instead, we recommend:
- I’M CHIPPED
- Owner’s surname
- House number + postcode
- Mobile phone number
This keeps your personal details minimal, meets legal requirements, and makes it as easy as possible for someone to get your dog home.
Why Tag Style Matters (And Why We Recommend Flexitag)
Not all ID tags are equal.
Traditional dangling tags can:
- Clink and jangle constantly
- Catch on crates, gates, or undergrowth
- Irritate sensitive or nervous dogs
- Wear away engraving over time
The Flexitag we recommend in our shop is made from durable biothane and slides directly onto the collar.
That means:
- Silent and non-dangling
- No swinging metal against your dog’s neck
- Clear, long-lasting engraving
- Comfortable for sporty, sensitive, or nervous dogs

Where Should an ID Tag Be Worn?
ID tags should always be attached to a properly fitted collar, not a harness.
Harnesses can be removed, slip off, or be taken off at home. A collar with ID provides consistent identification if a dog escapes.
For safety reasons, we recommend removing collars when dogs are crated or confined. Otherwise, wearing a collar with ID dramatically reduces risk if a door, gate, or lead fails.
FAQ
Do dogs legally need ID tags in the UK?
Yes. Dogs must wear identification showing the owner’s surname and address when in a public place.
Is a microchip enough on its own?
No. A microchip is a legal requirement, but visible ID is still required and helps dogs get home faster.
Should I put my dog’s name on the tag?
We don’t recommend it. Your contact details matter far more than your dog’s name.
Can I put the tag on a harness instead?
No. Tags should be attached to a collar, as harnesses can be removed or slip off.
