You let the dog out, turn around to fill the kettle, and when you look back the yard is empty. Most escapes are not a mystery once you look closely: a loose fence board, a hole behind the shed, a gate that did not quite latch, or a dog with a good reason to leave. This guide walks you through finding the weak spots, fixing them, and working on the reasons your dog wants out in the first place.

How we wrote this: the steps follow Dogs Trust’s advice on escaping and running away and keeping your garden dog friendly, Battersea’s guide to stopping a dog digging and PDSA’s vets’ tips on pet-friendly gardens. We put their advice in our own words and mark our own tips with “in our view”. All were checked on 2 November 2026. We did not test any of the products named here ourselves, and we do not show prices or ratings. This is not veterinary advice: if your dog may have eaten something toxic, call your vet straight away.

1. Work out why your dog wants out

Dogs Trust says the first job is to find out which situations make your dog want to leave, and how it is getting out. Its list of common reasons is worth going through one by one:

• Fear. Fireworks, storms, building work or strangers can make a frightened dog try to run and hide.
• Boredom. A dog with too little to do may go looking for something, especially if it can hear or smell dogs, people or traffic beyond the fence.
• Chasing. Cats, wildlife and anything that moves can trigger a dog with a strong chase drive.
• Excitement or frustration at something it can see but not reach.
• Worry about being alone. Some dogs try to get out to follow you or to avoid being left.

In our view, watch your dog in the yard for a few days and note when it heads for the fence and what set it off. A dog escaping to chase squirrels needs different help from a dog escaping in a panic during a storm.

2. Walk the fence line

Both Dogs Trust and PDSA put a strong, well-kept fence first. Dogs Trust lists the ways dogs get out of a garden: banging against fences, jumping over, digging underneath, chewing weak spots, and slipping through gates or gaps. PDSA adds that the fence must be tall enough that your dog cannot jump it, and that you should check regularly for tunnels under it.

In our view, walk the whole boundary slowly, ideally at your dog’s eye level, and look for:

• Gaps between panels, under the bottom rail or beside posts. Small dogs and puppies fit through surprisingly small spaces, as Dogs Trust points out.
• Loose, rotten or broken boards, and chewed patches.
• Hollows or fresh soil along the base, the first sign of a dig.
• Low sections where the ground rises near the fence.
• Hedges with thin patches a dog can push through.

Fix what you find before the dog goes out alone again, and repeat the walk every few weeks and after storms.

3. Clear the launch pads

Dogs Trust advises shifting bins, boxes and similar items clear of fences and walls, so they cannot become a ladder. In our view, the usual suspects are trash cans, log piles, garden furniture, planters, compost bins and a kennel or shed close to the boundary. Anything a dog can step onto turns a tall fence into a short one. A clear strip along the inside of the fence also makes digging easier to spot.

4. Make the gate the strongest part

Gates are a common way out. Dogs Trust says many dogs slip or squeeze through doors and garden gates when they are excited, scared or keen to follow someone, and that every gate, door and window should be closed, and locked where needed, before the dog goes out.

In our view, a self-closing hinge and a latch that clicks shut on its own take the human error out of it, and a padlock stops delivery drivers and visitors leaving it open. Check the gap under the gate and between the gate and post as well.

The front door is a related risk. Dogs Trust suggests putting your dog in another room or behind a baby gate before you open an outside door. Our best dog gate guide covers indoor gates, and how to get a dog used to a baby gate explains the training.

5. Stay out there, and use a long line

Dogs Trust’s advice is to stay with your dog in the garden and, if there is any risk it could get out, keep it on a lead or long line. That lets you guide it away from the fence before it starts working on it. Battersea suggests the same for diggers: a long line lets you move your dog away from favourite digging spots.

The Viper BioThane Long Line Lead is a fixed-length line of BioThane coated webbing with a brass snap, sold in several lengths, according to its listing. In our view, clip it to a harness rather than a collar, and never leave a dog alone while it is attached. Our guide on how to use a long line for dog training has the details.

6. Give digging a better outlet

Dogs Trust and Battersea both call digging normal dog behaviour, and Dogs Trust warns that trying to stop it altogether may frustrate or upset your dog. Battersea notes it can come from comfort, boredom or stress, and is more common in some breeds, such as terriers.

The fix both suggest is a digging pit. Dogs Trust describes sinking a sturdy container into the ground and filling it with soil or dog-safe sand. Battersea suggests a small sandpit placed away from the usual digging spot. Bury toys in it, show your dog where they are, and when it starts digging somewhere else, walk over to the pit and start hiding things there. Battersea also suggests fencing off the areas your dog likes to dig while it learns.

In our view, for a dog that digs at the fence line itself, add a barrier along the base, such as buried wire mesh bent inward or paving slabs laid along the bottom, so a dig hits something solid.

7. Cut the boredom

Dogs Trust links many escapes to a dog that is bored and looking for something to do. It suggests meeting your dog’s needs with the right amount of exercise for its age, health and size, plus regular walks, toy play, training, scent games and things to chew or lick. Its garden page adds herbs to sniff, things to climb, mixed textures, a shady quiet spot and fresh water.

PDSA makes a useful point: garden games are great, but your dog still needs its daily walks. Puzzle toys help too; see the best puzzle toys for dogs and how to teach a dog to use a puzzle toy.

8. Skip shock and invisible fences

Dogs Trust says to avoid equipment that works by causing pain or discomfort, and its escape advice is built on fixing the boundary and meeting the dog’s needs instead. In our view, that rules out shock collars and electric “invisible” fences. They do not stop a dog that is panicking or chasing, they can make a frightened dog more scared of the yard, and once a dog is through, the same zap stops it coming back. A real fence and a supervised dog are the safer pair.

9. Plan for the day it happens anyway

Even a well-fenced yard fails sometimes. Dogs Trust suggests a GPS tracker or collar as a way to find your dog quickly in an emergency. In our view, a tracker is a backup, not a fence: it tells you where your dog went, it does not keep it home. The Tractive Dog 6 GPS Tracker clips to your dog’s own collar and offers live tracking and safe zone alerts in the Tractive app, according to its listing. See the best GPS dog tracker and how to set up and use a GPS dog tracker.

In our view, also keep a tag on the collar with your phone number and keep your dog’s microchip details up to date. Our guide on what to put on a dog ID tag covers the wording.

If your dog does get out, Dogs Trust says not to shout, chase or tell it off when it comes back: shouting can scare it away, chasing can make it run further, and a telling-off makes it less keen to return next time. Follow calmly and reward it when it comes to you. Its recall training advice helps for the future.

While you are out there: hazards in the yard

PDSA lists common garden plants that are toxic to pets, including daffodils, crocuses, tulips, azaleas, laburnum, lilies and lily of the valley, and warns that slug and pest killers are also very toxic. Dogs Trust adds cocoa shell mulch, which dogs can be drawn to by the smell, and says not to leave plant clippings, chemicals or sharp tools within reach. PDSA suggests fencing off or covering a pond and keeping dogs off a newly seeded lawn for a few days, because grass seeds can work their way into ears, eyes and paws. If you think your dog has eaten something toxic, call your vet straight away rather than waiting for signs.

When to talk to your vet or a behaviourist

Dogs Trust recommends a vet check if escaping starts out of the blue for no clear reason, if your dog is suddenly scared of things it used to ignore, or if it has stopped coming back when called, since health problems can change behaviour without obvious signs. If a dog breaks through doors, gates or windows, or escapes when left alone, it suggests professional help from a qualified behaviourist who uses reward-based methods.

FAQ

How do I stop my dog from escaping the yard?

Find out why and how it gets out, then fix gaps, weak boards and dig spots, move anything it can climb, and make sure the gate always latches. Dogs Trust also suggests staying with your dog, using a long line while there is any risk, and giving it enough exercise and activity.

How tall should a fence be to keep a dog in?

Sources do not give one height for every dog. PDSA says it must be tall enough that your dog cannot jump it. In our view, judge it by your own dog’s size and jumping, and remember that anything placed near the fence lowers its real height.

How do I stop my dog digging under the fence?

Dogs Trust and Battersea suggest a digging pit as an outlet, supervision and a long line to move your dog away from the spot, and fencing off favourite areas while it learns. In our view, a barrier along the base, such as buried mesh or slabs, stops new tunnels.

Are invisible fences a good idea for dogs?

We do not recommend them. Dogs Trust advises against equipment that works through pain or discomfort, and in our view a frightened or chasing dog may run straight through the boundary anyway.
