Introduction
Seeing your dog clear the fence and disappear down the street is frightening. A loose dog can be hit by a car, get lost, or get into a fight. The good news is that most fence jumpers can be helped. Dogs rarely jump just to be naughty — they usually have a reason. Once you understand it, you can fix it with more exercise, a few simple yard changes, and calm, patient training.
Why Do Dogs Jump the Fence?
Boredom and loneliness. A dog left alone in the yard for hours gets bored, and the world beyond the fence looks interesting. Dogs are social animals and would rather be with people than alone outside.
Too much energy. Young and active dogs often have more energy than a short walk burns off. A tired dog is usually a calmer dog.
Curiosity. New smells, sounds, and sights beyond the fence are tempting — children playing, food smells, or another dog.
Prey drive. Some dogs have a strong urge to chase squirrels, cats, birds, or joggers. Once focused on something moving, the fence feels like a small obstacle.
Territory and guarding. Some dogs jump to chase away something they see as a threat, or to patrol a wider area. This is common in dogs that bark a lot at passers-by.
Separation anxiety. Some dogs panic when left alone and jump in a desperate attempt to find their owner. They often pace, whine, drool, or destroy things near the door as well.
Social motivation. Some dogs simply want to meet other dogs or people. For a friendly young dog, the fence can feel like a barrier between them and fun.
Watch your dog for a few days. When does it happen — when you leave, when another dog passes, or after a long time outside? The pattern points to the cause.
First, Make Sure Your Dog Is Safe Right Now
Do not leave a known fence jumper alone in the yard until you have made it safer. Supervise yard time, keep sessions shorter, and bring your dog inside when you cannot watch them. If you must leave them outside briefly, use a long lead on a secure harness — never a collar — and only while you can watch them. Never tie a dog out unsupervised for hours.
Check your dog’s ID tag and microchip details today, and make sure the phone number is correct. If your dog escapes, a tag and microchip greatly increase the chances of getting them home. Walk the fence line too, and fix loose boards, gaps underneath, and soft ground where your dog could dig.
Give Your Dog Enough Exercise and Mental Stimulation
Many fence jumpers are simply under-exercised and under-stimulated. A dog that has had a good walk and a chance to use their brain is far less likely to seek excitement over the fence.
Give daily exercise suited to your dog’s age, breed, and health — at least one good walk a day for most adult dogs, plus playtime. High-energy breeds may need more. Play fetch or tug, and let your dog sniff on walks; sniffing is tiring and enriching.
Mental stimulation matters just as much. Try food puzzles, snuffle mats, or a Kong stuffed with food. Teach a new trick, or hide treats around the house and yard for your dog to find. Even ten minutes of training a day helps. If your dog is alone for long hours, a dog walker or a lunchtime visit from a neighbour can make a big difference.
Remove Launch Points and Block the View
Dogs rarely jump from a standing start on flat ground — they often use something as a step. Move bins, boxes, wood piles, garden furniture, and anything climbable away from the fence. Even a low wall, compost bin, or raised bed close to the fence can give your dog the extra height they need. Keep a metre of clear space along the inside of the fence if you can.
If your dog jumps whenever a neighbour’s dog walks past, blocking the view can help. Add fence screening or bamboo panels to the spots your dog usually uses — you do not need to cover the whole fence. If your dog also digs under the fence, bury wire mesh or place large stones along the fence line, using materials that will not injure their paws.
Make the Fence Harder to Jump
If your fence is low, raising it is often the most effective fix. In many areas, a six-foot fence is the usual maximum for a backyard and is high enough to stop most dogs. Check local rules first. If you cannot raise the whole fence, focus on the section your dog uses most, adding an extension at the top angled slightly inward.
Coyote rollers are another useful option: long tubes on top of the fence that spin when a dog tries to grip them, so the dog cannot get a hold and drops back down. They are simple and humane, and work well for many dogs. For chain-link fences, privacy slats or screening can also help by blocking the view. Check posts, rails, and fixings regularly, especially after bad weather — a wobbly fence is easier to climb and more dangerous.
Teach Boundary Training and a Reliable Recall
Training is the long-term answer. You want your dog to learn that the yard is a good place to be, and that staying close to you is rewarding.
Start with boundary training. Walk your dog around the yard on a lead. When they move calmly near the fence, praise them and give a treat. If they rush towards it, gently guide them back and try again. Keep sessions short and positive — the goal is to reward calm behaviour near the boundary, not to scare your dog.
A reliable recall is also essential. If your dog heads for the fence, you need to be able to call them back. Practise in a safe, enclosed area first, starting with short distances and few distractions, then build up slowly. Reward your dog generously every time they come to you. For a full step-by-step guide, see our article on how to teach your puppy to come when called every time.
Teach a “leave it” or “wait” cue near the fence, too. When your dog looks at something beyond the fence but stays calm, praise or treat them at that moment. Our guide on how to keep your dog in your yard without a fence has extra practical tips on boundary training and supervision that work well alongside a fence. Be patient — training takes weeks, not days.
Supervise Yard Time and Reward Calm Behaviour
Supervision is also a training tool. When you are outside with your dog, you can catch good behaviour and reward it right away. When your dog is relaxed in the yard — lying down, sniffing calmly, or playing with a toy — praise them quietly and offer a treat. You are teaching them that the yard itself is rewarding.
Give your dog good things to do outside, such as a chew toy or puzzle feeder, and rotate toys so they stay interesting. Try not to let your dog practise jumping: every successful escape teaches them that jumping works. If your dog loves company, controlled social time can help too. Our guide on how to socialize a puppy safely explains how to do this step by step, without overwhelming your dog.
What NOT to Do
Do not punish your dog after they escape. Scolding them when they come home will not connect with the jumping — it will only teach them that coming back to you is scary, which makes recall harder.
Do not use shock collars, prong collars, or other pain-based tools. These cause fear, pain, and anxiety, and do not teach your dog what to do instead. A frightened dog may still jump, but now they are also stressed.
Do not chain your dog up for long periods. A tethered dog can become frustrated and anxious, and tethering carries serious safety risks, including tangling and injury.
Do not leave a chronic escape artist unsupervised. If your dog jumps every time they are alone outside, keep yard time supervised until you have made real progress.
Do not expect an instant fix. Fence jumping is a habit, and habits take time to change. Give the plan a few weeks to work.
Do not ignore sudden changes. If a dog that never jumped before suddenly starts trying to escape, there may be a new trigger, a change at home, or a health issue behind it.
When to See a Vet
Most fence jumping is a training and management issue, but sometimes it is worth talking to a vet or a qualified behaviourist. See your vet promptly if the escape attempts are sudden, frantic, or out of character, especially if your dog is panting heavily, drooling, pacing, whining, or injuring themselves while trying to get out. These could be signs of anxiety, pain, or another health issue, and a vet can check for possible medical causes.
Get professional help too if your dog shows signs of severe separation anxiety, such as panic when you leave, destructive behaviour, or self-injury. A vet or behaviourist can talk through possible options and create a plan that suits your dog. Never start any medication or supplement without veterinary advice. If your dog is older or has arthritis, jumping can also be dangerous for their joints — a vet can advise on safe exercise.
Frequently Asked Questions
How high should a fence be to stop a dog from jumping?
For most dogs, a six-foot fence is a good height. Large, athletic, or determined dogs can clear five feet or more, so if your dog already clears your fence, raising it, adding an inward-angled extension, or fitting coyote rollers is usually more effective than a small increase alone. Check local rules on fence height first.
Why does my dog only jump the fence when I am not home?
This is often boredom, loneliness, or separation anxiety. When you are home, your dog has company; when you leave, the yard can feel empty, or your dog may panic and try to find you. Try shorter absences, more exercise before you leave, and enrichment toys. If the panic seems severe, talk to your vet.
Can I train an older dog to stop jumping the fence?
Yes. Older dogs can learn new behaviour, though it may take a little longer. The same plan applies: more exercise and mental stimulation, remove launch points, make the fence harder to jump, supervise yard time, and reward calm behaviour. Ask your vet for advice if your older dog has joint pain or other health issues.
Will getting another dog stop my dog from jumping the fence?
Not always. A second dog can help with loneliness, but it can also learn escape tricks from the first dog — or both may jump together. Only consider a second dog if you genuinely want one and can care for it well, not just as a fix for fence jumping. Focus on exercise, enrichment, and training first.
What should I do if my dog escapes while I am working on the problem?
Stay calm. Go to places your dog knows, call them in a happy voice, and carry treats. Do not chase them — many dogs run further if chased. If you see your dog, crouch down, turn sideways, and let them come to you. Once home, check for injuries, give them water, and review what happened so you can make the yard safer.
Conclusion
A dog that jumps the fence is not a bad dog. They are usually bored, full of energy, curious, anxious, or trying to reach something interesting on the other side. Start with safety: supervise yard time and check the fence today. Then add exercise and mental stimulation, remove launch points, and make the fence harder to clear. Teach calm boundary behaviour and a reliable recall, and reward your dog every time they stay relaxed in the yard. Stay patient and consistent, and celebrate the small wins — with time, most dogs learn to stay home, safe where they belong.
