Lost dog: what to do in the first hour
Search the area on foot, tell everyone not to chase him, call the shelters that cover your area, and check the phone number on his microchip record.

The gate is open. You have called his name twice, already in a voice that is not your normal voice, and the street is very quiet.
For a lost dog, the first hour is legwork and phone calls, in that order. Search the immediate area on foot and tell every person you pass not to chase him. Call the shelters and the animal services that cover your area. Then open your microchip registration and check that the phone number on it is the one in your hand.
What do you do in the first hour?
Start on foot, close to home, before you start driving. Humane World for Animals recommends a thorough physical search of the area your dog was last seen, including backyards with the owners’ permission and nearby green space, before widening the perimeter. Most of the value is in the first few streets.
Tell everyone you meet. Two things come of it: they might spot him, and a dog nobody knows is missing looks to a stranger like a dog who needs a home. Ask each person for one specific thing. If they see him, call you, and do not chase him.
Take a phone, a leash, the treats he comes running for, and a recent photo you can send without scrolling for it.

Where do lost dogs actually go?
It depends on the dog, and the difference decides where you look. Humane World for Animals draws the line between two temperaments: a friendly, confident dog is more likely to turn up where people or other dogs gather, while a shy, frightened or injured dog, or one lost somewhere unfamiliar, is more likely to be hiding or running.
So the confident dog gets a search of the park, the school field, the busy corner. The frightened one gets quiet ground: under decks, in hedges, behind the sheds nobody walks past. Bring someone who can stay still and listen while you move.
This is also why chasing backfires. The same source is direct about it: do not attempt to chase down a skittish dog, because it can drive them out of the area. A scared dog reads a running human as pressure, and a two-street problem becomes a two-neighbourhood one. If he is visible but will not come, sit down, look away, and let him decide.
If he is around but will not approach anyone, the advice shifts from searching to waiting. Humane World for Animals suggests setting up a feeding station in a spot he is known to visit, watching it with a motion-activated camera to learn when he shows up, and then borrowing a humane trap, which most animal control agencies and many rescue groups will lend you.
Who do you call, and in what order?
Call the places a found dog physically ends up, then the places people post about one. Working down this list is the highest-value phone call sequence of the day.
| Who | What they can do | Ask for |
|---|---|---|
| Municipal animal services or the pound | Holds picked-up strays; has a scanner | A found report, and their intake hours |
| Every shelter your area delivers strays to | Holds strays and takes found reports | To file a lost report, then visit in person |
| Nearby vet clinics and emergency clinics | Where an injured or found dog gets taken first | To leave a description and your number |
| Your microchip registry | Flags the chip as lost, contacts you when scanned | To confirm your phone number and email |
| Neighbourhood apps and local lost-pet groups | Reach the people who are outside all day | A post with the photo and the last seen spot |
Visit the shelters yourself rather than trusting a phone description. Staff match a written description against a kennel full of dogs; you match your own dog.
In Toronto the sequence runs through 311 and three City shelters, set out in lost dog in Toronto. If the animal missing is a cat, the search is different, because cats hide rather than run: where to search for a lost cat in the first week. And whoever finds him is reading the other side of this page, tracing an owner from a rabies or licence tag.
Will the microchip get him home?
Only if the registry entry is current, and this is where most chips fail. The AVMA’s microchipping FAQ is blunt about the mechanism: a chip has no power source and no location, so it is not a GPS device and cannot track your animal. It carries a number. A shelter or clinic scans the number, identifies the registry, and calls whoever the registry has on file.
Which means the chip is only as good as the phone number attached to it. Humane World for Animals makes the same point from the other side: implanting a chip is not the same as registering one, and plenty of shelters and clinics implant without registering. If you have moved, changed your number, or adopted a dog who came pre-chipped, assume the entry is wrong until you have opened it.
The number itself is nine, 10 or 15 digits, and the AVMA notes that many countries require the 15-digit kind before a dog or cat may enter, so the chip that works at home is not automatically the one a foreign border wants. Humane World for Animals puts the hardware’s working life at 25 years, which is longer than most people keep the same phone number. The chip outlasts the contact details on it, every time.
Two things worth doing on an ordinary Tuesday rather than tonight. Ask your vet to scan the chip at the next routine visit to confirm it still reads, which the AVMA recommends. And keep the collar tag on, because the chip needs a scanner that a shelter has and your neighbour does not.
Do lost dog posters and online listings still work?
Yes, and the physical ones still do more than people expect. Humane World for Animals recommends large, colourful posters where the dog went missing, plus flyers handed to the people who are outside all day: dog walkers, mail carriers, runners. Grocery stores, laundromats, vet offices and dog parks take notices.
Online, post to local lost-and-found groups and to Petco Love Lost, a national database that matches an uploaded photo against found-pet listings using facial recognition. Neighbourhood apps carry the same post to the people whose doorbell cameras face your street.
One precaution, from the same source. Leave a single identifying feature out of everything you post, so that when a caller claims to have found him you can ask them to describe it. Be wary of anyone asking for money before they will hand your dog back. Before you send anything, check the caller through an independent contact, as lost pet scam calls explains.
What should be in the record before any of this happens?
The first hour is a bad time to be looking for a photo. Before anything goes wrong, keep five things somewhere every adult in the house can open from a phone: a current photo showing his markings, the microchip number and which registry holds it, his description with the one detail you will hold back, your vet’s number, and any medication he is on, since a shelter will ask.
Keep them in the same place the rest of his history lives. Our guide to pet health records covers the wider set, and the piece on getting pet medical records from the vet covers getting the documents out of the clinic in the first place. If a sitter or a walker has him while you are away, they need the same five things, which is why the sitter handoff includes them.
Where Dana fits
Dana keeps the microchip number and your preferred vet on the pet’s health record, next to the medication list a shelter will ask about, and every caregiver you invite with full access can open all of it from their own phone. His profile photo is already in the app, so the picture you need to send at 9 PM is not somewhere in a camera roll, and Records Vault, part of Dana Pro, holds the documents themselves.
Questions people ask
How long should I keep looking for a lost dog?
Longer than feels reasonable. Humane World for Animals notes that dogs lost for months, and even years, have been reunited with their owners, and that a systematic search beats a frantic one.
Should I run after my dog if I can see him?
Not if he is skittish. Humane World for Animals advises against chasing a frightened dog, because it can drive him out of the area. Sit down, look away and let him come to you, and if he still will not approach, set up a feeding station where he has been seen.
What if someone says they found my dog and asks for money?
Treat it as a scam. Humane World for Animals advises leaving one identifying feature out of your public posts so you can ask a caller to describe it, and being wary of anyone who wants payment before returning your dog.
Should my dog wear a collar tag if he is already chipped?
Yes. A tag is readable by the neighbour who finds him, while a chip needs a scanner that only a shelter or clinic has. Humane World for Animals calls identification tags the pet's first ticket home and the chip an essential backup.
