    Stop Your Dog From Digging Up Or Climbing Your Fence

    There is no doubt, dogs can get into just about anything and decide if the yard is good or whether it’s too boring so they want to explore beyond the borders. He might choose to dig under the fence or jump over the fence, then end up in a bad situation. One minute Jasper was there and the next minute he would up and disappeared. A big concern with most owners would be if he ended up in the road and seriously injured. Unsupervised, they can be quite vulnerable, causing property damage elsewhere, getting into a fight with another dog, or injured. Dog owners must find ways to keep their dogs happy and satisfied versus becoming distracted and bored.

    Why Dogs Escape & How To Stop It

    Before you can stop your dog from jumping over the fence, you have to understand why he or she is trying to escape. Once you understand some of the reasons, you can take steps to turn it around. Here are some of the most common reasons for your pet's actions:

    Boredom & Frustration

    In many cases, your dog is just looking for something interesting to get into because they spend the majority of the day alone at home. Especially if you have a puppy or young dog, they need to be stimulated to burn off built-up energy. Sometimes, he might be climbing over the fence or digging under it to get out and find a playmate. In other cases, it could be the breed of your dog. Some breeds are more active than others and need a lot of stimulation throughout the course of the day.

    If your dog is frustrated or bored, you might want to spend more time playing games with them. This will give him the chance to exercise his mental and physical skills. When in doors, keep him entertained by offering him toys, teaching him some new tricks, or coming up with new games to play with him.


    Separation anxiety can be a problem. Dealing with the situation will require behavior training and commitment on your part to deal with desensitization and counter-conditioning to help him through his anxieties. You should contact people who work with anxiety in dogs to learn how to spot these conditions and how to deal with them.


    If your dog encountered a very loud sound that frightened him, such as fireworks, he might jump the fence and disappear. There have been many cases when dogs have run away and it's taken a good amount of time to find them and bring them home. If there will be loud noises caused by construction, fireworks, or other situations, place him in a safe place if you know noises are something he fears. Keep the windows closed or if you have a soundproof room let him stay there for a short time. Read up on everything you can about fears that dogs experience and how to keep him safe and calm during these times. You might want to consider getting a microchip implanted should he get lost or takes off due to loud scary sounds. Contact your vet to get more information.


    Male dogs, usually around 6 months old, may possibly developed a sex drive and will attempt to go outside his boundaries to find a female mate. As an owner what can you do to stop him from jumping the fence if he's looking for a mate? The best solution is to get your dog neutered or if you have a female have her spayed by your vet. It will keep your dog from roaming up to 90% and dogs that have neutered or spayed usually live a longer life and not run the risk of getting cancer. If you plan on breeding, our advice is to talk with breeders for other alternatives to keep your dog from breeding young pups at will.

    If it's feasible, you could get a companion dog if this seems to be what he or she is looking for. Another alternative is to have your dog socialize more often with other animals and people. If nothing else, set up play dates with your neighbor's pets or take him or her to a dog park.

    More Solutions For Fence Jumping or Digging

    Get behaviorist training, plenty of exercise, socializing, and providing toys to keep your dog busy and entertained instead of jumping fences. The best solution is keep your dog inside. If you are going to be away for a while or will be working late on some days, consider finding a kennel to take care of your dog or bring in a pet sitter. In some cases, you vet might have a solution. Offer deterrents to prevent escaping if your pet never takes “No” for an answer. Here are somethings you can do to stop the digging and jumping:

    • Attach a lean-in or L-footer Section To Your Fence.
    • Clean up all objects in your yard that he or she might use as a climbing tool.
    • You might choose to mount coyote rollers – Coyote rollers are aluminum tubes designed to spin when your your pet tries to exit or enter a fenced in area. They will not get the traction they need to get over the fence. The rollers are maintenance free and will not harm your pet.
    • Plant bushes or shrubs to make it harder for your dog to climb. There are some plant scents that might be effective in making your dog want to stay in your yard.
    • Block his view to the outside world.
    • Consider installing an airlock or double gate.
    • Create an obstacle course in your yard.

    In Conclusion

    Never fall under the belief that dogs do not think on their own or do not suffer from their own anxieties and fears. If you pay close attention, you will find out what's causing their behavior issues. When possible, consult with people who have been around, raised, and trained dogs for a very long time. Every time you see a commercial with a dog jumping through hoops or other objects, that dog has been trained for a long period of time, they did not develop these skills on their own. Reach out to those who can help you out with some tricks they have learned over time or have been passed on to them. Dogs are wonderful companions and deserve all the help and understanding you can give them. In the long run, it will pay off in so many ways.
