Why Does My Dog Dig and Cover Feces?

Instinct Drives Digging and Covering

Dogs dig and cover feces primarily due to instinct. This behavior is not about being "bad" but rooted in natural canine tendencies. Many dogs bury food, toys, or bones to save them for later—similar to how ancient dogs protected their resources. This is especially common in breeds like terriers, bred to hunt vermin underground. Even if your dog isn’t hunting, the urge to dig can stem from a need to create a safe space, such as a den for a pregnant dog.

Digging also serves as a way to manage scent. Dogs may dig to aerosolize or cover their own scent, or to leave a new scent mark. This behavior is part of their communication system with other animals. When a dog covers feces, it’s often an instinct to hide the evidence—just as wild canids do to avoid attracting predators.

Boredom, Stress, and Environmental Triggers

If your dog is left alone in the yard with little to do, digging becomes a form of entertainment. Active dogs need mental and physical stimulation. Without it, they may turn to digging to relieve boredom or stress. This is similar to how humans might bite their nails when anxious.

Dogs may also dig to cool down on hot days, seeking the cooler soil beneath the surface. Some dogs are drawn to underground activity if they sense prey like mice or snakes. If your dog is digging near a hole or tunnel, it may be trying to reach something beneath. In such cases, safely removing the underground animals and supervising your dog outdoors can help reduce the behavior.

Redirecting the Behavior Humanely

Instead of punishing your dog, redirect the behavior with better options. Provide a designated digging zone in the yard where your dog is allowed to dig. Fill it with toys, bones, or treats to make it appealing. This gives your dog a safe outlet for their natural instincts.

You can also offer indoor alternatives—like hiding treats under blankets or in a toy box—so your dog learns to “bury” items without damaging your yard. Supervision is key: prevent unsupervised access to areas where digging is unwanted. If your dog has a habit of burying bones, temporarily withhold those items until the behavior improves.

Using Positive Reinforcement and Management

The most effective way to change behavior is through management and positive reinforcement. If your dog digs and finds feces, they may stop and react negatively—dogs dislike the smell and taste of their own waste. This natural aversion can be used to discourage digging.

One method involves placing dog poop at the bottom of existing holes, covering it with dirt. When your dog digs again, they’ll hit the poop and likely avoid that spot. This teaches them the consequence without punishment. Repeat as needed if they start new holes. The goal is to shift the game so your dog learns the rules through experience, not force.

When Digging Becomes a Problem

While digging is normal, it can become excessive and indicate deeper issues. If your dog digs constantly, can’t be interrupted, or damages property severely, it may be a sign of obsessive-compulsive behavior. Early intervention is key. If standard management doesn’t help, consult your veterinarian to rule out medical or behavioral concerns.

Remember: dogs are washable, and they can learn new habits. With patience, consistency, and humane strategies, you can redirect your dog’s instincts into positive outlets.
