How to Choose a Custom Pet ID Tag: Size, Material, and What to Engrave

A pet ID tag is one of those things you don't think about until you need it — and then you really need it. Here's what actually matters when you're choosing one.

Size: Match the Tag to the Dog

A tag that clangs against a Great Dane's chest is fine. The same tag on a 6-pound Chihuahua is a nuisance. General guide:

  • Small dogs under 20 lbs: 3/4" or 1" tag
  • Medium dogs 20–60 lbs: 1" to 1.25" tag
  • Large dogs over 60 lbs: 1.25" or larger

For cats, a small 3/4" tag is usually best — lightweight enough that it doesn't bother them.

Material: Stainless Steel vs. Aluminum

We engrave pet tags in stainless steel and aluminum. Here's the honest difference:

  • Stainless steel: heavier, more durable, doesn't tarnish. Better for active dogs who swim, dig, and roughhouse.
  • Aluminum: lighter and more affordable. Fine for indoor cats or small, calm dogs.

Laser engraving on either material is permanent — it removes material from the surface, so it won't wear off or fade regardless of how many baths or puddles your dog gets into.

What to Engrave on a Pet Tag

Front of the tag:

  • Pet's name (large, easy to read)

Back of the tag:

  • Your cell phone number (primary)
  • A second number (optional backup)
  • "Microchipped" if applicable — this prompts a vet scan
  • City/state only — not your full address for privacy

Skip: breed, long messages, email addresses. In a real lost-pet situation, someone needs to be able to read the tag at a glance and call a number. Keep it simple.

Horse Tags

We also make custom engraved horse tags for halters and blankets. These are larger format — typically 1.5" to 2" — and include the horse's name, barn name, and your contact number. Ideal for boarding facilities, trail rides, and shows.
