The main name and phone details should be recognisable without holding the tag directly under your eyes.
A tag only works when a stranger can read it quickly.
Dog tags take daily knocks from collars, leads, bowls, rain and muddy walks. A monthly check takes less than a minute and helps make sure the important details can still be read when they are needed.
Updated 2 August 2026One worn or ambiguous phone-number digit can make the whole contact line unusable.
Replace a tag when the hole, ring or surrounding metal is badly worn, cracked or distorted.
The 30-second readability test
Remove loose dirt, hold the tag in normal indoor light and read it from roughly arm’s length. Ask another person to read the owner details and phone number without prompting. If they hesitate over a letter or digit, the engraving is no longer doing its job reliably.
- Read the tag in ordinary light, not only under a bright torch.
- Check both the front and the optional engraved back.
- Confirm the phone number against the number saved in your phone.
- Look for digits that can be confused, such as 3 and 8 or 1 and 7.
Look beyond the engraving
A readable tag can still need replacing if the attachment point is failing. Check the split ring, the hole in the tag and the edge around it for thinning, sharp burrs, cracks or stretching. The tag should hang freely without catching on the collar hardware.
When to replace the tag
Replace it when any essential owner detail is difficult to read, the phone number has changed, the address is no longer current, or the attachment area is damaged. Do not wait for every line to disappear before ordering a new one.
- An important letter or number is unclear.
- The engraving is visible only at a particular angle.
- The tag has deep scratches across the contact details.
- The ring or attachment hole is close to failing.
- Your owner, address or phone details have changed.
Make the replacement easier to read
Keep the owner's name and address readable, then add the phone number most likely to be answered. Use the reverse or compare a larger tag if the complete wording is crowded. The live DogTag.ie preview warns when the chosen wording needs to be shortened.
Simple replacement engraving examples
Irish collar identification calls for the owner's name and address; a pet name, message or phone number does not replace those details. The labels below are planning placeholders. Enter your actual wording and check every selected side in the preview before ordering, including any optional pet name or message.
- Owner name placeholder: ALEX SAMPLE
- Owner address placeholder: YOUR ADDRESS
- Additional contact placeholder: 08X XXX XXXX
- Avoid long sentences, decorative symbols and multiple phone numbers on the same line.
Good to know before you order.
How often should I check a dog tag?
A quick monthly check is sensible, with an extra check after the tag has taken a hard knock or the collar hardware has been changed.
Should I replace a scratched dog tag?
Light cosmetic marks are not necessarily a problem. Replace the tag when scratches cross important details, make a letter or digit ambiguous, or weaken the attachment area.
What should I put on a replacement dog tag?
Plan readable space for the owner's name and address first, then add a useful phone number. A pet name or short message is optional. Check the full wording in the preview and use the reverse or compare a larger tag if more room is needed.
Is a readable phone number enough?
A phone number is extremely useful, but Irish regulations specify the owner’s name and address. Keep all essential identification current and readable.
