Most lost dogs aren't found by animal control. They're found by somebody three streets over who spots a friendly dog in their driveway and has no idea what to do next.
That's the moment a tag is for. A microchip is worth having, but it only works if the dog makes it to a vet or a shelter with a scanner. A tag works right there in the driveway, from a phone, in about ten seconds.
What goes on the tag
Your phone number. That's the part that matters most, and it's the part people leave off surprisingly often.
Use your cell, not a landline. If your dog goes missing you'll be out walking the neighborhood, not sitting by the kitchen phone. Some people put two numbers on, theirs and a partner's or a neighbor's, which covers you if your phone dies at the worst possible moment.
Your dog's name is optional and there are two schools of thought. A name helps a stranger calm your dog down and makes the whole thing feel less like a rescue operation. Some owners leave it off because they'd rather a stranger not be able to call their dog over by name. Both positions are reasonable. Pick the one you'll sleep better with.
Skip your home address. It doesn't help anyone reach you faster and it tells a stranger where you live.
If your dog needs daily medication or has a condition that matters in an emergency, a short note is worth the space. Something brief. Whoever finds your dog isn't going to read a paragraph.
The word people forget
"Reward."
It sounds cynical. It works. Not everyone who finds a nice dog picks up the phone right away, and a small nudge shortens the gap between found and returned. You don't have to name an amount.
Cheap tags fail in ways you don't notice
The failure isn't dramatic. It's slow. Stamped letters on a thin tag wear down against the collar hardware until the number is a guess. Soft metal bends. A rough edge rubs a spot raw under the chin where you won't see it during a normal day.
Stainless steel and brass hold up. Enamel keeps its color. Deep engraving stays readable after a few thousand walks, which is the only real test.
Check the tag every few months. Run your thumb over it. If you can't read the number in bad light, replace it.
Our dog ID tags are engraved rather than stamped, in stainless steel, brass, and enamel.
A tag for every collar
This is the part that goes wrong in most houses.
You've got the everyday collar, the nice one for visits, maybe a spare after the muddy walk. The tag lives on the everyday collar. So on the day the nice collar is on and the front door gets left open, your dog is out there wearing nothing useful.
Put a tag on every collar your dog owns. Tags are cheap. Doing it once removes a decision you'd otherwise have to remember at exactly the wrong moment.
While you're at it, write your number on the inside of the collar in permanent marker. Tags come off. The collar usually doesn't.
Fit matters more than you'd think
Two fingers flat between the collar and your dog's neck. Not two fingers stacked.
Too tight is uncomfortable and, over time, harmful. Too loose is a different problem. A loose collar can slip over the ears when a dog backs up hard against a leash, which is exactly when you need it to hold. It can also catch on a fence post or a crate door.
Puppies need this checked constantly. Growing dogs outgrow a collar faster than most people expect. Set a monthly reminder if you've got a young dog.
Our collars come in a range of widths, so a small dog isn't stuck carrying hardware built for a retriever.
Worth doing this week
Take the tag off. Read it in daylight. Is the number current? Is it the number you'd actually answer?
People change phones and forget the tag. It's the most common failure we hear about, and it takes about four minutes to fix.
