Dogs are drawn to paper for a mix of reasons: it’s fun to shred, it smells interesting, it makes satisfying sounds, and sometimes it signals an underlying need. Most paper-chewing is normal exploratory or play behavior, but persistent eating of paper can point to boredom, anxiety, or even a dietary gap worth addressing.
Paper Is a Perfect Chew Toy (to a Dog)
From your dog’s perspective, paper checks a lot of boxes. It tears easily, creating that ripping sensation dogs find inherently rewarding. It crinkles and makes noise when pawed or mouthed. And it’s lightweight enough to toss around, carry, and “kill” like prey. For puppies especially, mouthing and chewing non-food objects is a normal part of exploring the world, not a sign of anything wrong.
Dogs also have roughly 300 million scent receptors compared to about 6 million in humans. Paper, particularly used tissues, napkins, paper towels, or mail you’ve handled, carries a rich signature of organic scents. Your skin oils, food residue, and even the wood-pulp base of paper itself all register as interesting to a dog’s nose. That’s why your dog may ignore a fresh stack of printer paper but go straight for the crumpled napkin on the coffee table.
Anxiety and Frustration, Not Disobedience
If your dog shreds paper mainly when you’re away, separation distress is a likely driver. Research published in Applied Animal Behaviour Science found that destructive behavior during separation stems from frustration tied to the dog’s attachment to its owner, not from boredom or spite. That frustration triggers heightened arousal, which can spill over into play-like or predatory-like behavior: tearing, chewing, scratching. Destructive chewing is often directed at exit points like doors and windows, but dogs also target specific household objects, and a wastebasket full of paper is an easy mark.
Dogs can also learn to anticipate your departure based on cues like grabbing keys or putting on shoes, which ramps up anxiety before you even leave. If you consistently come home to shredded paper near the door or in rooms where you spend the most time, separation-related frustration is worth investigating with a veterinary behaviorist.
A Possible Sign of Dietary Deficiency
When a dog doesn’t just shred paper but actively eats it, the behavior may reflect a nutritional gap. A veterinary case study documented a poodle with a long-term habit of eating plants, which resolved completely after switching to a high-fiber diet. The dog had been eating plants daily and vomiting afterward for an extended period. Once its diet was changed, the behavior stopped and had not returned after 13 months of follow-up. The researchers concluded the dog was seeking fiber its commercial dry food wasn’t providing.
Paper is a wood-pulp product, essentially plant fiber, so the same logic may apply. Dogs eating paper, cardboard, or sticks could be attempting to supplement a fiber-poor diet. This doesn’t mean every paper-chewing dog is fiber-deficient, but if your dog repeatedly seeks out and swallows paper rather than just tearing it up, a conversation about diet composition is worthwhile.
When Paper Chewing Becomes Pica
Occasional shredding is play. Persistent, compulsive eating of non-food items is a condition called pica. The distinction matters: a dog that tears up a tissue and spits out the pieces is behaving normally, while a dog that seeks out and swallows paper, fabric, or plastic despite your efforts to prevent access has a pattern that needs attention. Pica can be driven by anxiety, compulsive disorders, gastrointestinal disease, or nutritional imbalances, and identifying the root cause is the key to stopping it.
Health Risks of Eating Paper
Small amounts of plain paper generally pass through a dog’s digestive system without trouble. The bigger concerns are volume, type, and what’s on the paper.
Large quantities of paper, especially if swallowed in compressed wads, can cause a gastrointestinal blockage. According to Cornell University’s College of Veterinary Medicine, signs of a foreign body obstruction include vomiting, loss of appetite, abdominal pain, diarrhea, dehydration, and lethargy. Dogs with a full obstruction can become seriously ill from dehydration or, in severe cases, infection that spreads from the gut. If your dog has eaten a large amount of paper and shows any of these signs, that warrants urgent veterinary care.
The chemical composition of paper adds another layer. Newspaper inks, particularly older petroleum-based formulations, contain polycyclic aromatic hydrocarbons (PAHs), compounds linked to cancer risk with prolonged occupational exposure. Ink pigments can also carry trace amounts of heavy metals. Modern soy-based inks are significantly lower in volatile compounds, but they’re not completely free of them. Bleached paper historically involved chlorine processing that produced dioxins, though most manufacturers have shifted to chlorine-free methods. In practical terms, a dog chewing on a piece of newspaper occasionally faces minimal chemical risk. A dog regularly consuming printed paper is getting repeated low-level exposure to substances that aren’t meant to be ingested.
How to Redirect the Behavior
The right approach depends on why your dog is doing it. For dogs that simply enjoy the sensory experience, providing alternatives works well. Crinkle toys, puzzle feeders, and durable chew toys satisfy the same urges without the risks. Keeping wastebaskets behind closed doors or using lidded bins removes the easiest targets.
For separation-related destruction, the goal is reducing the underlying anxiety rather than just removing paper. Gradual desensitization to departure cues, increased exercise before you leave, and enrichment toys that keep your dog occupied during the first 20 to 30 minutes of alone time (when arousal peaks) all help. Severe cases may benefit from behavioral medication prescribed by a veterinarian.
If your dog is eating paper rather than shredding it, start with a dietary review. Adding fiber through veterinarian-approved sources, or switching to a higher-fiber food, may resolve the behavior entirely if a nutritional gap is the trigger. If the behavior persists despite dietary changes and adequate enrichment, a veterinary workup can rule out gastrointestinal conditions or other medical causes driving the compulsion.
