What to Do When You Find a Dog in the United States
When you find a dog in the United States, make sure you and the dog are safe, check for an ID tag, and take it to a vet clinic or shelter to be scanned for a microchip. Then report the dog to the animal control agency for the place where you found it, post a found dog ad, and hand the dog back only to someone who can prove it is theirs.
A found dog usually has an owner who is already searching, and acting quickly gives them the best chance of getting it back before shelter time limits run out.
Key points
- Do not approach a dog that seems aggressive, injured or sick; call animal control instead.
- Check for a tag, then get a microchip scan at a vet clinic or shelter; many scan at no charge.
- Report the dog to animal control for the area where you found it; some cities require this within 24 hours.
- Post a found dog ad, but hold back one identifying detail to check callers.
- Hand the dog back only after the owner proves ownership with records, photos or a microchip match.
How do you safely catch and hold a found dog?
Texas A&M's veterinary college puts safety first: if you see a stray in traffic, pull over safely, and do not approach a dog that seems defensive. A frightened dog may bite even if it is friendly at home.
- Approach slowly, turn sideways and crouch down; let the dog come to you.
- Use treats and a calm voice, and slip a leash over the head rather than grabbing the collar.
- If the dog will not come, or seems injured or sick, call your local animal control and keep watch from a distance.
- At home, keep the dog in a separate room or yard area away from your own pets until a vet has checked it, as you do not know its vaccination status.
- Give fresh water and a little food, and note anything unusual about the dog's health to tell the vet or animal control.
How do you check a found dog for a microchip?
First check the collar for an ID tag, rabies tag or license tag. The license or rabies tag number can often be traced through the city, county or vet that issued it.
If there is no tag, take the dog to a vet clinic or shelter and ask for a microchip scan. Many do this at no charge, but call first. If the dog has a chip, staff can look up the number in the AAHA Universal Pet Microchip Lookup, which shows which participating registry holds the record. The registry then contacts the owner. Some registries do not take part in the lookup, so staff may need to contact the chip maker directly.
Do you have to report a found dog to animal control?
Often, yes, and even where it is not required, reporting is the best way to reach the owner, because people searching for a lost dog usually file a report with their local animal control or shelter. Rules are set by states, counties and cities, so they differ. Some examples:
- San Mateo, California requires anyone who finds or picks up a stray to report it to the animal shelter within 24 hours and release it to the shelter on request.
- Summit County, Utah requires a finder to notify animal control within 24 hours.
- Elsewhere the deadline may be longer or shorter, so check your own city or county code or ask animal control.
Contact the agency for the place where you found the dog, not necessarily where you live. Many shelters will let you keep the dog at home while they hold it on record as a stray, which keeps shelter space free and lets you file a found report instead of handing the dog in.
| Step | Where | Why |

| Post a found dog ad | PetzLover and local online groups | Reaches owners searching online |
| Put up flyers | Near where you found the dog | Many lost dogs are found close to home |
How do you post a found dog ad?
On PetzLover you can post a free found dog ad. Include the area and date where you found the dog, its size, sex and color, and a clear photo. Leave out one detail, such as a scar, a special marking or the collar color, so you can ask callers to describe it. People can reply by message.
Also look through lost dog listings near you for a match, and read what to do when your dog is lost to see where owners are likely to be searching. Put up a few flyers near where you found the dog, with a photo and the words FOUND DOG.
How do you verify the owner before handing the dog back?
- Ask the caller to describe the dog, including the detail you left out of the ad.
- Ask for photos of them with the dog, and vet records, a license or adoption papers in their name.
- If the dog is chipped, check that the chip is registered to the person claiming the dog, or ask a shelter or vet to confirm.
- Watch how the dog reacts: a happy greeting is reassuring, but a nervous dog may not show it straight away.
- Meet at a vet clinic, shelter or other public place, and bring a friend.
What if no owner comes forward?
Shelters hold strays for a set period so owners can reclaim them. According to the Animal Legal & Historical Center, most states require 3 to 5 days, from 48 hours in Hawaii to 10 days in Missouri, but these laws cover shelters and pounds, not private people who take in a stray. Finding a dog does not automatically make it yours, so ask your animal control what you must do before you can keep or rehome it.
If you decide to keep the dog once the legal steps are done, take it for a full vet check, vaccinations and a microchip in your name. If you cannot keep it, work with a shelter or rescue. Owners looking for their dog can read how to find your lost dog through found-pet ads, and neighbors helping a search can use how to help find a lost dog.
Frequently Asked Questions
What should I do first when I find a dog?
Make sure you and the dog are safe, and check its collar for an ID or license tag. Then take it to a vet clinic or shelter for a microchip scan. Report it to animal control for the area where you found it.
Where can I get a found dog scanned for a microchip?
Vet clinics and animal shelters have scanners and often scan found dogs for free; call ahead. If a chip is found, staff can use the AAHA Universal Pet Microchip Lookup to see which registry holds the record. The registry then contacts the owner.
Can I keep a dog I found?
Not straight away. You usually need to report the dog and give the owner time to reclaim it, and rules differ by state and city. Ask your local animal control what applies before you keep or rehome the dog.
Do I have to take a found dog to the shelter?
Not always. Many shelters let you keep the dog at home and file a found report, but some cities require you to hand the dog over on request; San Mateo, California is one example. Ask your local animal control which option applies.
How do I know the person claiming my found dog is the real owner?
Ask for a description including the detail you left out of your found dog ad, plus photos and vet, license or microchip records in their name. Meet in a public place such as a vet clinic. If you are unsure, ask animal control to handle the return.
Should I post a found dog ad if I already reported the dog?
Yes. Many owners search online as well as calling shelters, so a found dog ad reaches more people. Keep your phone number private and let people message you through the site.
