Why Dogs Eat Drywall: Causes & Risks

What Is Pica in Dogs?

Pica is the term used for pets eating nonfood items. In dogs, this includes things like grass, socks, toys, and even drywall. While the exact cause isn’t always clear, it’s often tied to behavioral or medical factors. Some dogs eat nonfood items out of boredom or due to a lack of mental stimulation. Others may do so because of nutritional deficiencies or underlying health problems affecting digestion or nutrient absorption.

The behavior can become a habit, especially if the dog gets attention or relief from chewing. Since drywall is not digestible, swallowing it can lead to serious health risks, including blockages or internal injuries.

Common Causes of Nonfood Eating

Dogs may eat nonfood items for several reasons. Boredom is a frequent trigger—dogs need mental and physical engagement to stay healthy. Hunger or nutritional deficiencies can also drive a dog to seek out unusual sources of nutrients. For example, some dogs eat poop (coprophagia) in an attempt to gain missing nutrients, especially if their diet lacks balance.

Tooth problems may also contribute, as chewing on hard objects like sticks or drywall can relieve discomfort. In some cases, dogs eat nonfood items simply because they like the texture or taste. This is similar to why some dogs eat grass—because they enjoy the crunch or moisture, not necessarily because they need fiber or nutrients.

Risks of Eating Drywall

Drywall is not safe for dogs to eat. It is made of gypsum and paper, both of which are indigestible and can cause serious harm. If swallowed, drywall can lead to choking, intestinal blockages, or tears in the digestive tract. These complications may require emergency surgery, just like when dogs swallow socks, plastic toys, or fish hooks.

Even if the drywall passes through the system, it can irritate the stomach and intestines, leading to vomiting, diarrhea, or loss of appetite. The risk is especially high in larger pieces or if the dog eats it frequently.

When to See a Veterinarian

If your dog eats drywall, especially repeatedly, it’s important to consult a veterinarian. Sudden or obsessive behavior may signal an underlying medical issue such as gastrointestinal upset, parasites, food sensitivities, or inflammatory bowel disease. Signs like greasy, yellow stools, weight loss, or lethargy should prompt an immediate vet visit.

Even if your dog seems fine, persistent nonfood eating should not be ignored. A vet can help rule out health problems and recommend dietary or behavioral changes to prevent future incidents.

How to Prevent Drywall Eating

Prevention starts with managing your dog’s environment. Keep drywall debris out of reach, especially during home renovations. Provide plenty of appropriate chew toys and mental enrichment activities to reduce boredom. Ensure your dog’s diet is balanced and meets all nutritional needs.

If your dog shows signs of pica, work with a vet or animal behaviorist to address the root cause. Training and consistent boundaries can also help redirect unwanted behaviors. Never leave a dog unattended with small or chewable objects, including damaged drywall.
