Dear Cathy,
I adopted a Lab/Pug mix from a local shelter, and we just love her. Unfortunately, she’s a digger. She is digging up our tree and lilac roots, which she pulls out and chews up. I’m hoping it might be a vitamin deficiency that we can fix with nutrition; otherwise, any suggestions? I put her poop in the holes, filled the holes with dirt, and dragged her to the holes after the fact and told her no. I have heard mouse traps work, but that seems mean. I have a dog door to the backyard, so I don’t have complete control of when she’s going outside. I also have a Shih Tzu, so I don’t want to block them from going outside altogether. – Jane, M.
Dear Jayne,
Digging is a natural behavior for many dogs, and it can be challenging to stop completely. While it’s often self-rewarding—fun, entertaining, and instinctual—there are plenty of ways to discourage it safely and redirect the behavior in a positive way.
First, I want to address the use of mousetraps, as you mentioned hearing about them. Mousetraps are absolutely a no-no. Not only could they physically harm your dog by snapping on paws or noses, but the sudden, frightening experience could psychologically affect her, especially if she’s a timid or skittish dog. Scaring her like that could lead to other behavioral problems, such as anxiety or fearfulness. Let’s focus on safer, natural solutions to help you and your dog.
Since she’s targeting specific areas, like the tree and lilac roots, you can try natural deterrents to make those spots less appealing. For example, crushed eggshells or small rocks sprinkled around the plants can discourage digging because dogs often dislike the texture on their paws. Additionally, you can mix citrus peels—like lemon or orange—and scatter them near the base of the plants. Most dogs dislike the strong scent of citrus, so it may deter her from digging without harming the plants or her.
Another option is to create physical barriers to discourage her from accessing these areas. A small garden fence around the base of the trees or lilacs can work wonders, and if she steps over it too easily, you can crisscross twine or wire a few inches above the ground. This creates a roadblock that is gentle but effective in making those areas less appealing for digging.
However, because digging is often a way for dogs to entertain themselves—especially when they’re left alone in the yard—it might be easier to redirect her energy rather than stop it completely. Consider creating a designated digging pit just for her. A 3×6-foot sandbox or dirt patch can provide a positive outlet for her digging instincts. To make it exciting, bury toys, treats, or small pieces of hot dogs in the sand and encourage her to “dig here” with a fun and upbeat tone. When she uncovers a treat, praise her and give her another small reward to reinforce the behavior. Over time, she’ll learn that her special “digging zone” is the best place to dig.
If you’re worried about nutritional deficiencies being the cause of her chewing on roots, it’s a good idea to check with your veterinarian to rule out any dietary concerns. Sometimes, dogs will chew or dig for reasons like boredom, lack of enrichment, or instinct, but it’s always worth confirming her diet is balanced and meets her needs.
Since you have a dog door and can’t always supervise her, ensure she’s getting plenty of physical and mental stimulation. Long walks, puzzle toys, and interactive play can tire her out and reduce the need to entertain herself in the yard. Dogs with pent-up energy often resort to digging or other unwanted behaviors, so burning off that energy can make a big difference.
Ultimately, the combination of natural deterrents, a designated digging space, and enrichment will help her break the habit while still allowing her to engage in her favorite activity. By redirecting her energy and setting boundaries, you’ll both find a happy balance—your lilacs will thank you, and so will your dog!
