Dogs chew clothes because the fabric carries your scent, has an appealing texture, and is easy to grab. The specific reason behind the behavior depends on your dog’s age, emotional state, and daily routine. In most cases, it comes down to one of a handful of common triggers: teething, boredom, anxiety, or a compulsive eating disorder called pica.
Your Scent Is the Biggest Draw
Dogs experience the world primarily through smell, and your clothing is saturated with your scent. Dirty laundry, socks, and underwear are the most common targets precisely because they carry the highest concentration of your body’s oils and sweat. For your dog, chewing on these items is comforting in the same way a child clings to a favorite blanket. It’s not random destruction. Your dog is choosing your clothes over other household objects because those items smell like you.
This is especially true when you’re not home. A dog left alone may seek out items from a laundry basket or bedroom floor because your scent provides reassurance. If the chewing happens almost exclusively when you’re away, separation anxiety is likely playing a role (more on that below).
Teething in Puppies
If your dog is under six months old, teething is the most likely explanation. Puppies begin losing their baby teeth and growing adult teeth around 12 to 16 weeks of age. The process is painful, and chewing provides relief by putting pressure on sore gums. Clothes are soft, flexible, and everywhere on the floor, making them a perfect target for a teething puppy that doesn’t know the difference between a chew toy and your favorite shirt.
Teething-related chewing typically peaks between three and six months and tapers off once the adult teeth are fully in. During this window, offering safe chew toys and keeping laundry off the floor solves most of the problem. Frozen rubber toys can be especially soothing on inflamed gums.
Boredom and Understimulation
An adult dog that chews clothes during the day, especially one that’s otherwise healthy, is often just bored. Dogs need both physical exercise and mental engagement. Most dogs benefit from at least 30 minutes of active mental stimulation per day through training, puzzle toys, scent games, or interactive play. Without it, they’ll find their own entertainment, and your wardrobe is conveniently available.
High-energy breeds and working breeds are particularly prone to this. A Labrador or Border Collie that gets a 20-minute walk and nothing else will almost certainly redirect that unused energy into chewing. The fix isn’t just more running. Mental challenges like food puzzles, snuffle mats, or short training sessions burn through mental energy in ways that a walk alone can’t. Dogs that get a balanced mix of physical and cognitive activity are far less likely to shred your socks.
Separation Anxiety
When clothes chewing happens specifically while you’re gone, separation anxiety is a strong possibility. Dogs with this condition become distressed when left alone and may chew, dig, bark, or pace as coping mechanisms. They gravitate toward items with your scent because it’s the closest thing to your presence.
The telltale signs that anxiety is driving the behavior: the chewing only happens when you’re out, your dog shows signs of distress as you prepare to leave (pacing, whining, following you room to room), and the destruction is focused on personal items or exit points like door frames. Mild cases sometimes improve with gradual desensitization, where you practice short absences and slowly increase the duration. More severe cases often need guidance from a veterinary behaviorist, and sometimes anti-anxiety medication alongside behavior modification.
Pica: When Dogs Actually Eat the Fabric
There’s an important distinction between chewing clothes and swallowing them. Pica is a condition where dogs compulsively eat non-food items like fabric, rocks, or plastic. According to UC Davis School of Veterinary Medicine, pica can stem from nutritional deficiencies, underlying medical problems, anxiety, boredom, or true compulsive behavior. If your dog is actually ingesting pieces of clothing rather than just shredding them, a veterinary evaluation is important to rule out nutritional gaps or gastrointestinal issues driving the behavior.
Some breeds, particularly Labrador Retrievers and Siamese-mix cats (for the feline equivalent), seem more predisposed to fabric-eating behaviors. But pica can develop in any breed, and it’s one of the few causes of clothes chewing that signals a potential medical problem rather than a purely behavioral one.
The Real Danger: Intestinal Blockages
The biggest health risk from clothes chewing isn’t the behavior itself. It’s what happens when a dog swallows fabric. Socks, underwear, and pieces of torn clothing can cause gastrointestinal obstruction, where the material gets stuck in the stomach or intestines and can’t pass through naturally.
Warning signs of a blockage include vomiting, loss of appetite, lethargy, and abdominal pain. Diarrhea and weight loss are less common but possible. According to the Merck Veterinary Manual, if a swallowed object hasn’t passed within 36 to 48 hours, or if symptoms like vomiting and lethargy worsen, surgical removal is typically necessary. That surgery ranges from $2,000 to $3,000 at a general practice, and $3,000 to $5,000 if a board-certified surgeon handles the case, which is usually recommended when complications like intestinal rupture are involved.
If you know your dog swallowed a piece of clothing and starts showing any of these symptoms, don’t wait it out. Early intervention makes the difference between a routine procedure and a life-threatening emergency.
How to Stop the Behavior
The most effective first step is management: remove the opportunity. Keep laundry in closed hampers, bedroom doors shut, and clothes off the floor. This alone eliminates most incidents while you work on the underlying cause.
Bitter apple spray and similar taste deterrents can help protect items you can’t always put away, like couch cushions or blankets. These sprays use bitter or spicy flavors that most dogs find unpleasant. You’ll need to reapply daily for two to four weeks until your dog learns to avoid the treated items. Before spraying everything, test a small amount on a cotton ball and let your dog sniff it. If your dog recoils or drools, the deterrent will likely work. Some dogs are unfazed by bitter tastes, so it’s worth checking first.
Beyond management, address the root cause. For boredom, add puzzle feeders and daily training. For anxiety, work on gradual alone-time training. For teething puppies, provide plenty of appropriate chew alternatives and redirect every time they grab clothing. Consistency matters more than any single product or technique. A dog that gets caught with a sock and is calmly redirected to a chew toy dozens of times will eventually learn. A dog that gets yelled at will just learn to chew clothes when you’re not watching.
Age-Specific Patterns
Puppies under six months are almost always teething. Adolescent dogs (six months to two years) are often testing boundaries, burning excess energy, and still learning household rules. This age group tends to be the most destructive overall, and the behavior usually decreases naturally with maturity, training, and adequate exercise.
Adult dogs that suddenly start chewing clothes after months or years of leaving them alone deserve closer attention. A new chewing habit in an older dog can signal a change in routine, a new source of stress, the onset of a medical condition, or cognitive decline in senior dogs. The sudden onset is the key detail. Lifelong chewers need better management and enrichment. New chewers need a closer look at what changed.
