What to do if your dog is lost: a step-by-step checklist

Updated October 13, 2026 · LostPet.com

Take a breath. Most lost dogs do get home. In an ASPCA-funded national survey, 93% of lost dogs were recovered, and the most common way owners found them was searching the neighborhood (Weiss et al., 2012). Fast action matters. Here's what to do, in order.

Is your dog hurt, or did someone find an injured dog? Call a vet or emergency animal hospital first. Use our vet directory to find one nearby.

In the first hour

1. Search your home and yard. Ask everyone in the house where they last saw your dog. Check under beds, in closets, behind furniture and in small, dark spaces. Shaking a treat jar or food bowl can bring a hiding pet out (ASPCA).
2. Search the neighborhood right away. American Humane notes many lost pets stay fairly close to home in the first hours (American Humane). Walk or drive slowly. Bring a recent photo, treats, a leash and a familiar blanket or toy.
3. Call calmly, don't chase. Use a calm, steady voice. Shouting can scare an anxious dog further away (American Humane).
4. Ask neighbors to check sheds, garages and fenced yards, in case your dog got shut in (ASPCA).
5. Leave someone at home if you can, with the door or gate ready, in case your dog comes back.
6. Call your microchip registry. Report your dog missing and confirm your phone number and address are current (American Humane). Not sure which registry? See how to check your pet's microchip.
7. Report your dog lost on LostPet.com. Report your pet lost and search pets that have been found near your ZIP code. It's free. If your dog is already registered, the photo and details are saved, and My Pets can print a flyer with a QR code on the spot.

In the first day

Call, then visit. Call local animal control, shelters (city and private), rescue groups, vet clinics and emergency animal hospitals. One of them may already have your dog (ASPCA). Find them fast in our shelter directory and vet directory.

Then go in person, with photos, and check back daily (ASPCA). A dog's appearance can change after time outdoors, so a phone description isn't always enough (American Humane).

Post online. Share a clear photo, your dog's name, a description and where they were last seen on local lost-pet pages, neighborhood Facebook groups and Nextdoor (American Humane). Ask friends to share. Update your posts and reply quickly to sightings.

Put up flyers. The ASPCA suggests (ASPCA):

• a big, bold headline like LOST DOG that people can read from a distance,
• a clear, recent photo,
• breed, sex, color, age, weight and any markings,
• when and where your dog was last seen,
• your name and two phone numbers.

Post them near where your dog went missing and in busy places: dog parks, pet stores, groomers, vet offices, grocery stores, gas stations and cafes. Use one design so people recognize it.

If your dog is lost at night

Keep looking with a flashlight. American Humane notes many lost animals move more freely at night, when neighborhoods are quieter and traffic slows (American Humane). Go slowly, stop often, and listen. Start calling shelters and vets as soon as they open.

Will a microchip find my dog?

A microchip is not a GPS tracker. It only gives an ID number when a vet or shelter scans it (AVMA). That's why your registry needs your current number, and why you should still check shelters in person.

Watch out for lost-pet scams

Scammers watch lost-pet posts. The FBI warns about people who claim to have your pet but can't send photos, make excuses about meeting, or ask for money or a Google verification code (FBI).

• Ask for a detail you didn't post, or a new photo.
• Never send money or share a code from your phone.
• Meet in a safe public place, and bring a leash (American Humane).

Don't give up

Some pets come home within hours. Others are found weeks or months later, through shelter visits, neighbors or a microchip scan (American Humane). Keep checking shelters, and refresh your flyers and posts.

When your dog is home

• If your dog seems hurt, sick or not themselves, call your vet.
• Update the tag and chip if anything changed. See what to put on a pet ID tag and microchip vs. ID tag.
• Thank the people who helped and take down your flyers and posts.
• Busy nights are risky. Plan ahead for Halloween and fireworks.

Quick checklist: what to do if your dog is lost

1. Search your home and yard. Check under beds, in closets, behind furniture and in the garage. Shake a treat jar.
2. Search the neighborhood. Walk or drive slowly with a photo, treats and a leash. Call calmly; use a flashlight at night.
3. Call your microchip registry. Report your dog missing and confirm your phone number.
4. Report your dog lost online. Report your dog lost on LostPet.com and post on local lost-pet pages.
5. Call and visit shelters, animal control and vets. Call them all, then visit shelters in person with photos, daily.
6. Put up flyers. LOST DOG headline, clear photo, description, where last seen and two phone numbers.
7. Keep going and watch for scams. Keep checking shelters. Never send money or share a verification code.

Frequently asked questions

What should I do first if my dog is lost?

Search your home and yard, then the neighborhood right away, with a recent photo and treats. Ask neighbors to check sheds and garages. Then call your microchip registry, report your dog lost, and call local shelters, animal control and vets.

What should I do if my dog is lost at night?

Keep searching with a flashlight and call your dog's name calmly; shouting can scare an anxious dog further away. American Humane notes many lost animals move more freely at night when streets are quieter. Keep someone at home in case your dog comes back, and start calling shelters as soon as they open.

How do I find a lost dog with a microchip?

A microchip is not a GPS tracker, so it can't show where your dog is. It helps when a shelter or vet scans your dog and contacts the registry. Call your registry now to report your dog missing and confirm your phone number, and keep checking shelters in person.

Should I check shelters even if my dog is microchipped?

Yes. Call and visit shelters and animal control from the first day, even if your dog has a chip and a tag. Collars can come off, and visiting in person helps because a dog's appearance can change after time outdoors.

How long should I keep searching for my lost dog?

Keep going even after several days. American Humane says some pets are reunited within hours and others weeks or months later, through shelter visits, community outreach or microchip identification. Keep checking shelters and refresh your posts and flyers.

Someone says they found my dog. How do I know it's real?

Ask them for a photo or a detail you didn't include in your post. The FBI warns about scammers who ask for money or a Google verification code. Never send money or share a code. Meet in a safe public place and bring a leash.
