Dogs Eating Drywall? Causes & Fixes

Why Do Dogs Eat Drywall?

Dogs may eat drywall because they are stressed, bored, or driven by their natural scavenging instincts. This behavior, known as pica, involves eating non-food items like paper, wood, or stones. When dogs are under stress, they may frantically gulp down anything they can find, including inedible materials like drywall. This over-eating is often a coping mechanism, not a sign of hunger.

In some cases, dogs may have learned to eat non-food items during a past life of scarcity, such as a rescue dog who scavenged on the streets. These dogs are highly opportunistic and may not hesitate to eat anything within reach, especially when left alone.

Is It a Medical Issue?

While drywall eating is not typically caused by nutrient deficiencies, some dogs may eat non-food items if they have malabsorption syndrome or a ravenous appetite due to illness. If your dog is eating drywall and also shows signs of illness—such as greasy, yellow stools—consult your vet immediately. However, in most cases, the behavior is not due to a medical condition but rather to stress, boredom, or learned habits.

Why Punishment Doesn’t Work

Scolding or punishing your dog after the fact is ineffective. Dogs don’t connect the punishment with the behavior because they don’t understand cause and effect in this context. In fact, they may learn to hide the behavior, making it harder to detect. The dog may even develop a “guilty” look not because of wrongdoing, but because of your reaction.

Punishment also fails to address the root cause—stress, boredom, or the instinct to scavenge. Instead, it can increase anxiety and worsen the behavior over time.

How to Stop the Behavior

The most effective way to stop drywall eating is to prevent access and replace the behavior with healthier alternatives. Here’s what experts recommend:

• Remove temptations: Keep your dog away from areas with drywall or other chewable materials. Close doors, use baby gates, or secure workspaces.
• Provide mental stimulation: Offer problem-solving toys, food puzzles, or scavenger games to burn off the energy your dog once used for scavenging.
• Train during your presence: Teach your dog to engage in safe, rewarding activities when you’re home. This helps redirect their focus and builds better habits.
• Be vigilant: If your dog has a history of eating non-food items, supervise them closely and intervene early.

When to See a Vet

If your dog eats drywall and shows signs of illness—such as vomiting, diarrhea, lethargy, or changes in appetite—see your vet right away. Ingesting drywall can cause intestinal blockages or injuries from sharp particles. Even if your dog seems fine, a vet check-up can rule out underlying medical issues like malabsorption or gastrointestinal disorders.
