    Why Dogs Dig

    Before you can decide on the best course of action to stop your dog's behavior, you need to find out why he or she is digging. We have listed some of the most common reasons:

    Dig & Run!

    Some dogs dig for the sole purpose of escaping or hiding food. Also, there are dog breeds that are known for digging, it's in their DNA:

    • Dachshunds
    • Malamutes
    • Siberian Huskies
    • Jack Russells
    • Chow Chows
    • Beagles
    • Bloodhounds
    • Basset Hounds

    To Hide Bones

    There are times dogs will dig a hole to bury a bone for another day. This is known as hereditary behavior that came from wild dogs who would bury their food and consume it later.

    The Smell Of Bone Meal

    By nature, dogs have a phenomenal sense of smell. If you have used bones or blood meal in your garden, your dog will dig to find the food source.

    Due To Boredom

    Boredom is a leading cause why dogs dig. Breeds that are considered very intelligent like border collies, German shepherds, and poodles, can become bored quite easily. Also, if your dog is left alone for a long period of time, or not getting enough interaction in their life, will find a way to satisfy that boredom by digging.

    Trying To Chase Small Animals

    Dogs who have a strong instinct for prey will be drawn to something going on beyond the fence and think it's prey such as squirrels, cats, or rabbits. This is common in hounds and terriers.

    Your Dog Is In Guard Mode

    If your dog thinks his territory is being threatened, otherwise known as your property, he might try to eliminate the problem. This is a strong trait in some breeds of dogs including German Shepherds Rottweilers, Bullmastiffs, Dobermans, and Australian Shepherds to name a few.

    Your Dog Is Lonely

    Dogs are very social animals and if he or she is left alone for long periods of time, they will look for companionship. He might look for you, a family member, or other dogs.

    Searching For A Mate

    This is true for males who are not neutered and are looking for a mate. The need to mate can take over any discipline to remain in the backyard.

    Caused By Stress

    There are many reasons that can cause your dog to suffer from stress. When under stress, he or she might try to escape simply because they feel confined. It can also be caused by anxiety or they are afraid of something going on like a thunderstorm or fireworks.

    Attempting To Escape From Heat

    In the summer months, it's not unusual for your dog to dig in order to find a cool spot to sit. Always make sure your dog has ways to keep cool. Make sure there are shaded spots throughout the course of the day. As dogs do not sweat, they must be able to cool down. In reverse, during colder times, they will dig a hole to get warm.

    Your Dog Is Pregnant

    If your dog is pregnant, she will dig a hole known as denning, to create a safe place where she can give birth. Out of instinct, she might dig several holes for nesting.

    Keep Your Dog from Digging Out

    Digging can be mostly an annoyance until your dog decides to dig near fence. If they are persistent they may be able to escape this can be a huge issue. Consider using a type of underground barrier to make it impossible for your dog to escape your backyard. Constructed of durable HDPE, these barriers are designed for decades of use and protrude 18” or more into the ground which will help to deter even the most persistent digger.

    In Conclusion

    Dogs have many reasons for digging holes but none are meant to annoy you. If they are trying to escape, you need to figure out why and find out if it's just curiosity or is it stress. Possibly, they want to bury a bone for a future date or are genuinely bored from the lack of attention. When you pay attention to your dog, you will be able to find out what's going on. Your dog is your friend, so be a friend and help them out.
