Finding a stray dog can be stressful — for you and for the dog. But knowing the right steps to take can make the difference between a quick reunion and a prolonged ordeal. In the UK, there is a legal process to follow when you find a stray dog, and ignoring it could put you in a difficult position.
Here's exactly what to do, step by step.
Step-by-Step: What to Do When You Find a Lost Dog
First, secure the dog. If it's on a busy road, guide it gently to a safe area. Use your own lead if you have one, or improvise with a belt or scarf. Don't chase it — crouch down and let it approach you if it's nervous.
Look at the collar for any tags. In the UK, it is a legal requirement (Control of Dogs Order 1992) for dogs in public places to wear a tag showing the owner's name and address. If there's a phone number, call it immediately.
Take the dog to the nearest vet, rescue centre or dog warden. They can scan the dog for free to retrieve the 15-digit microchip number. Most vets will do this without charge as a community service.
Once you have the chip number, search it on Petchip Global's microchip lookup or other recognised UK databases. If the dog is registered, the owner's contact details will appear and you can get in touch directly.
This is a legal requirement. Under the Environmental Protection Act 1990 (as amended by the Clean Neighbourhoods and Environment Act 2005), you must report a found stray dog to your local council within a reasonable timeframe. Your local authority has a statutory duty to collect stray dogs.
Share a photo on local Facebook groups, Nextdoor, and apps like Doglost.co.uk or PetsLocated.com. The owner may already be searching and these platforms have a strong track record of reuniting dogs quickly.
Call nearby rescue centres and your local council's dog warden service to let them know you have a stray. They maintain records of dogs reported missing and can cross-reference with your find.
Can I Keep a Stray Dog?
Many people who find a friendly stray dog immediately wonder if they can keep it. The short answer is: not right away.
Under UK law, a stray dog is treated as lost property. You must report it to the local council. If the dog goes unclaimed after a period (typically 7 days in council kennels), ownership may transfer — but the rules vary by local authority. You should never assume you can simply keep a stray dog without going through the proper process.
What If the Dog Has No Microchip?
If the dog is unregistered or unchipped, the search becomes harder. Your best options are:
- Report to the local council and let them take it to a registered kennel
- Post photos widely on social media with a description of where you found the dog
- Put up flyers in the area where you found it
- Contact local vets in case someone has reported a missing dog matching that description
What If the Owner Cannot Be Found?
If the owner does not come forward within the legal holding period and you wish to rehome the dog yourself, speak to your local council and a reputable rescue organisation. They can guide you through the formal process.
How Microchip Registration Helps
This entire process is dramatically simplified when a dog is properly microchipped and registered. A vet scans the chip, searches the database, and has the owner's contact details within minutes. No lost posters. No extended kennel stays. No uncertainty.
If you own a dog and this article has made you check your own registration — good. Make sure your details are current. If you move, change your number, or change your email, update your registration.
