If you're deciding what to put on a dog tag, start with what helps a stranger get your dog home quickly: your dog's name and a current phone number you actually answer. For many dogs, those two lines cover the basics. Everything else depends on how much room the tag has and what your dog needs.
What you include depends mainly on the size of the tag, your dog's needs, and how much space you have for readable engraving. A tiny tag for a toy breed can't hold what a large bone-shaped tag can, so some decisions are needed.
This guide covers what to include, what to leave off, and realistic examples for different situations. It also covers how to use the back of the tag and how to attach it securely. If you're new to the basics, start with our guide to dog tags.
Quick Answer: What Should You Put on a Dog Tag?
For most dogs, useful dog tag information includes:
- Your dog's name
- A current phone number
- A second phone number, if space allows
- Medical or special-needs information, if it applies to your dog
- Your town, city, or address, if you want to include it
- A short line such as "Microchipped" or "Lost? Please Call"
You don't need all of these. Choose what fits your tag and your dog, and keep the lettering large enough to read.
What to Put on a Dog Tag
A dog tag has one job: helping whoever finds your dog get in touch with you. Every line you engrave should serve that purpose. Here's how the options break down.
Essential Information
For most pet ID tags, the lines to have on a dog tag are:
- A current phone number. This is one of the most useful pieces of information to include because a finder can act on it right away. Use a number you carry with you, and include the area code.
- Your dog's name. A name gives the finder something to call your dog, and it makes the phone call easier: "I found Max" is quicker to confirm than a description of a brown dog.
Some owners weigh these differently, especially on very small tags. The section on small tags below covers how to prioritize when space is tight.
Optional Information
Depending on the tag size and your dog's situation, these details can be worth adding:
- A second phone number, such as a partner, family member, or trusted neighbor
- Your town, city, or street address
- A short medical or behavior note
- "Microchipped," so the finder knows a scan can help confirm ownership
- A short prompt such as "Lost? Please Call"
Choose the options that matter for your dog rather than trying to fit all of them.
Information You Probably Don't Need
Your full name, your dog's breed or age, an email address, and long messages rarely help in the moment. An email address can take up valuable space on a small tag, while a phone number gives a finder a direct way to contact you. The more you engrave, the smaller the letters get, and a crowded tag can be hard to read on a dog who won't stand still. If a line doesn't help someone contact you, it's usually better left off.
What Information Should Be on a Dog ID Tag?
Here's a closer look at each piece of information and when it makes sense to include it.
Your Dog's Name
Many owners put the name on the front of the tag. Calling a dog by name may help a finder get its attention and can make the interaction easier. The name also helps a shelter, vet clinic, or neighbor match your dog to a lost-pet post.
Some owners prefer not to put the dog's name on the tag for personal safety or security reasons. That's a personal choice. If you leave the name off, make the phone number prominent.
Your Phone Number
A phone number lets someone contact you from the spot where they found your dog, which is why it deserves clear, easy-to-read lettering.
A few practical tips:
- Use a number you keep with you and answer from unknown callers.
- Set up voicemail so a finder can leave details if you miss the call.
- Add a second number if you can, in case your phone is off or out of range.
- If your phone number changes, update the tag so a finder can still reach you.
Your Address or Location
An address can help if a neighbor finds your dog and can walk them home. It can also be a fallback when your phone is unreachable.
It's optional, though. Some owners prefer not to display their home address, and a full address takes up a lot of room on a small tag. A middle ground is your street name, or just your town or city, which still tells a finder your dog is probably local. Others leave location off entirely. If you move often, keep in mind that an address will need updating along with the tag.
Medical or Special-Needs Information
If your dog has a condition a finder should know about, a short note can change how they handle the situation. Useful wording includes:
- NEEDS MEDICATION
- DIABETIC
- DEAF or HEARING IMPAIRED
- BLIND
- NERVOUS, APPROACH SLOWLY
A note like "Needs Medication" tells the finder that contacting you is urgent. Only add medical wording when it genuinely applies to your dog, and keep it brief. The tag isn't the place for dosages or full medical history.
Dog Tag Examples
The examples below show a few ways to lay out a tag. They're examples, not required formats. Adjust the wording to your dog, your tag size, and what you're comfortable sharing.
Simple Dog Tag Example
This layout works for many dogs and fits on most standard tags:
MAX
555-123-4567
LOST? PLEASE CALL
The name comes first, the phone number is easy to spot, and the last line tells the finder what to do. If space is tight, you can drop the third line and keep the first two.
Standard Dog ID Tag Example
If your tag has room for four lines, a second contact adds a backup:
BELLA
555-123-4567
ALT: 555-987-6543
SPRINGFIELD
The alternate number covers the times your phone is off, and the town name tells a finder your dog is likely close to home. You could swap the town for "MICROCHIPPED" if you'd rather not share a location.
Dog Tag Example for a Dog With Medical Needs
When your dog has a health condition, placing the medical note near the phone number helps both get read together:
COOPER
NEEDS MEDICATION
555-123-4567
PLEASE CALL ASAP
This tells the finder there's a time-sensitive reason to reach you. For a dog with a sensory condition, "DEAF" or "BLIND" can replace the medication line.
Small Dog Tag Example
On a tiny tag, every character counts:
LULU
555-123-4567
Two lines engraved in larger letters are usually easier to read than four lines squeezed onto the same surface. If there's leftover space, a critical medical note is often a better use of it than extra details.
What to Put on the Back of a Dog Tag
Most tags can be engraved on both sides, which roughly doubles your space. The key is deciding what goes where.
The front generally works best for the information a finder needs first, which for many owners is the dog's name and main phone number. The back can hold secondary details: a second number, a medical note, your town, or "Microchipped." For example:
FRONT:
MAX
555-123-4567BACK:
NEEDS MEDICATION
555-987-6543
A finder may not think to flip the tag over, so keeping the primary contact information on the front can make it easier to notice. A useful test is to imagine someone reading only one side. Could they still reach you?
The back also rubs against the collar and your dog's fur, so that side may show wear sooner. That's another reason to check the engraving on both sides from time to time.
Dog Tag Ideas: What Else Can You Include?
Once your name and number are covered, a few extra lines can make the tag more helpful. Here are practical dog tag ideas worth considering:
- A second phone number. Useful if you work somewhere you can't always answer.
- "Call my owner" or "Lost? Please call." A clear instruction takes away any hesitation about what to do.
- "Needs medication." Signals urgency without taking much space.
- "Microchipped." Lets the finder know a vet or shelter can scan your dog to help confirm who they belong to.
- "Nervous, approach slowly." Helps a stranger handle a fearful dog more carefully.
- A key condition. One word such as "Diabetic," "Deaf," or "Blind."
- Reward wording. Some owners like "Reward if found." Others prefer to leave it off. It's a personal choice.
Funny or decorative text, like "I'm friendly, my owner isn't," can be fun on a large tag. Add it only after the useful information is in place and still readable. On a small tag, it's usually better to skip it.
The same thinking applies if you're deciding what to put on a dog name tag. The name is a nice start, but the contact details are what help a finder reach you.
Dog Tag on Collar: What Information Should You Include?
A tag isn't the only place to display ID. Many owners also have contact details embroidered or engraved directly onto the collar, and some use both.
Information on the collar itself has a few advantages. It doesn't jingle, it doesn't dangle, and it stays in place if a tag ring comes loose. With personalized dog collars, the name and phone number are visible along the band.
A dog tag on a collar has its own strengths. It can hold more lines, it's easy to replace when your details change, and you can move it to a new collar. A common setup is to put the name and phone number on the collar and use the tag for a second contact or medical note.
If you're deciding what to put on a dog collar, the same core details apply. A collar band has limited width, so long messages rarely fit well.
Both share one limitation: if your dog slips out of the collar, the information goes with it. That's why a tag or collar ID works best alongside a microchip, which stays with your dog. A microchip is most useful when its registration details are current, so update them whenever you update the tag.
How to Put a Dog Tag on a Collar
Most dog tags attach with a split ring or a tag clip. Either way, attach the tag securely to the collar's D-ring and make sure the ring or clip is fully closed so the tag can't slide off.
Keep the tag on the D-ring rather than near the buckle, so it doesn't get in the way when you fasten or release the collar. If you're choosing new dog collars, a sturdy metal D-ring makes it easier to hold both a tag and a leash clip.
Check the attachment periodically. Rings and clips may loosen or wear over time, and engraving can fade until the numbers are hard to read. While you're at it, confirm the collar still fits well. Our guide on how tight a dog collar should be explains how to check.
How to Choose What Fits on a Small Dog Tag
Small tags are common for small dogs and puppies, and they force you to rank what goes on. A practical order for many owners is:
- Phone number
- Dog's name
- Important medical or safety information
- Secondary contact
- Optional information, such as town or "Microchipped"
Your order may differ. For example, a dog with a serious condition might need the medical note ahead of the name. Work down your list and stop when the text starts getting cramped. Short, readable lines are generally more useful than a full address in tiny letters.
A few space-saving tips:
- Use short forms such as "MEDS" or "ALT" when the meaning stays clear.
- Use the back for the second phone number.
- Choose one clear instruction instead of several.
- Ask to see a preview before engraving, if the option is available.
If your dog's needs outgrow a small tag, consider a slightly larger tag or adding collar ID so nothing important is left off.
Frequently Asked Questions About Dog Tags
What should I put on my dog's tag?
Most owners start with their dog's name and a current phone number. If there's room, a second phone number and any medical note your dog genuinely needs can follow. Details like your town or "Microchipped" can go on the back. The goal is a tag someone can read quickly and act on.
What information is on a dog tag?
Many pet ID tags include the dog's name and at least one phone number. Many also include a second contact, a town or address, or a short medical or behavior note. Pet ID tags are different from military dog tags, which carry a service member's identification details. Pet tags exist to help a lost dog get home.
Should I put my dog's name on the tag?
Many owners do, since a name can help a finder get your dog's attention and makes the phone call easier to confirm. Others leave it off for personal safety or security reasons. Either choice is reasonable. If you skip the name, give the phone number the most prominent spot on the tag.
Should I put my address on my dog's tag?
It's up to you. An address can help a neighbor return your dog, but it takes up space and shows where you live. Some owners include only their street name or town, and some leave location off. If you rent or move often, remember the tag will need updating each time.
What should I put on the back of a dog tag?
The back works well for secondary details: a second phone number, a medical note, your town, or "Microchipped." Since a finder may not flip the tag over, many owners keep their main contact information on the front where it's easier to notice.
What should I put on a dog tag if it is very small?
Focus on the details that help someone reach you, usually a phone number and your dog's name. If your dog has a critical condition, a one-word note such as "Diabetic" may be worth the space. Fewer lines allow larger lettering, and the back can hold a second number.
Can I put a phone number instead of an address?
Yes, and many owners prefer it. A phone number lets a finder contact you right away, while an address relies on someone being willing to bring your dog to your door. It also keeps your home location private. Just keep the number current.
Final Thoughts
For most dogs, the most useful tag is one that helps a finder contact you quickly. Start with the details that make that possible, add a second contact or medical note if there's space, and use the back for anything secondary. Keep the lettering clear rather than trying to fit everything.
If you're creating a new tag, choose the information that matters most in an emergency, keep the engraving easy to read, and update it whenever your contact details change. When you're ready, Pawtons' custom dog tags let you engrave exactly what your dog needs.
