Why Does My Dog Steal Things? What Their Behavior Might Mean

Your dog steals a sock and runs around the house with it. You get on a Zoom call, and suddenly they're tearing apart a napkin. Or maybe you come home to find that your dog has chewed the corner of a rug, shredded a pillow, or pulled everything out of the garbage.

Dogs take things we'd prefer they leave alone for all sorts of reasons. Some are looking for interaction with us, others are enjoying the activity itself, and in some cases stealing, chewing, or destroying objects may be associated with frustration, anxiety, or a medical concern. The behaviors can look remarkably similar even when the reasons behind them are quite different.

A dog who takes your shoe because it starts a fun game of chase may have a very different motivation from a dog who carries your clothing to their bed when you're away. Even when dogs take similar objects, the circumstances surrounding the behavior can tell us very different things. To understand why your dog is stealing something, we need to look at more than just what they took.

n just what they took.

Why Does My Dog Keep Stealing Things? Look at What Happens Before

In behavior analysis, we use the term antecedent to describe what happens before a behavior. It's one of the first things I ask about when a client tells me their dog has started stealing things around the house. Think about what was happening immediately before your dog picked something up. Were you talking on the phone? Did someone just arrive at the house? Did you sit down to watch a movie? Were you preparing to leave, or had your dog already been home alone?

Perhaps your dog gets excited when visitors arrive, and a few minutes later you find them tearing apart a throw pillow. Or your dog rarely shows interest in household objects, but when you settle onto the couch for the evening, they begin carrying things around the living room. Looking at what happened before the behavior helps us identify situations where it's more likely to occur.

Distant Antecedents: What Happened Earlier in the Day?

We also want to consider distant antecedents, events or conditions occurring earlier that may influence behavior later. Your dog might have missed their usual walk and spent several hours resting while you worked. They may have had an unusually exciting afternoon, missed their normal nap, or experienced several stressful events. By the time you sit down to watch television, your dog could be restless, overstimulated, or looking for something to do.

Distant antecedents don't trigger the behavior directly, but they can change how likely it is to occur when the opportunity comes along. This is why I encourage people to think about what their dog's entire day looked like, rather than focusing exclusively on the moment something went missing.

What Your Dog Steals or Destroys Can Offer Clues

What your dog takes can provide useful information, particularly when you start noticing patterns. An object's appeal may have nothing to do with an underlying emotional problem. Some dogs develop strong preferences for particular textures, smells, or activities, while others seem willing to investigate anything they can get their mouths on.

Age, developmental stage, and individual tendencies matter here, too. A young adolescent dog who's still exploring the world with their mouth may have a very different relationship with household objects than an older dog who's never shown much interest in them. Teething can increase chewing in puppies, while breeds with a strong inclination to carry or retrieve objects may particularly enjoy picking things up and bringing them around the house.

Why Does My Dog Steal My Socks, Shoes, or Clothes?

Dogs may be especially interested in objects carrying familiar human odors. Socks, shoes, clothing, bedding, pencils, remote controls, and other things we regularly handle can all be appealing. Some dogs enjoy the scent, others like carrying or chewing the objects, and some have learned that picking up certain belongings gets a predictable response from people.

A dog who takes your socks when you're home and immediately brings them to you might be looking for interaction. A dog who carries your clothing to their bed while you're away may enjoy having something with a familiar scent nearby. That doesn't automatically mean the dog has separation anxiety or needs more attention. We'd want to know what else happens when people leave, how the dog behaves while alone, and whether the same behavior occurs when everyone is home.

Why Does My Dog Steal Paper, Fabric, and Things They Can Shred?

Dogs can find destruction enormously entertaining. Paper makes an interesting sound when it tears, cardboard can be pulled apart, fabric provides resistance when tugged, and stuffed objects offer opportunities for digging, pulling, and dissecting. For a young or enthusiastic dog, shredding a paper towel might be an incredibly satisfying activity, even when they're getting plenty of exercise and enrichment.

Chewing, tearing, and shredding are normal dog behaviors, and the activity itself can be rewarding without any interaction from people. In fact, we often incorporate cardboard boxes, paper, and other shreddable materials into enrichment activities specifically because dogs enjoy taking them apart. A dog who steals a piece of cardboard and happily shreds it may simply have found an entertaining activity.

The more important consideration is whether your dog is shredding objects or actually swallowing the materials. A dog who tears apart a cardboard box and leaves the pieces behind is doing something quite different from a dog who regularly swallows fabric, stuffing, or other non-food items. Ingestion can create medical concerns depending on the material and amount, which we'll discuss further below.

Why Does My Dog Steal Food, Garbage, and Dirty Napkins?

If your dog is stealing dirty napkins, food wrappers, used paper towels, sanitary waste, or things out of the garbage, smell may be a big part of the attraction. Dogs are excellent scavengers, and a napkin that smells like last night's dinner may be considerably more interesting than a perfectly good chew toy. Other discarded items may carry bodily odors that dogs find interesting even though they aren't food.

The dog may have learned that investigating the garbage occasionally produces something wonderful. In fact, a history of unpredictable food discoveries can make checking the trash particularly persistent. A dog who raids the garbage while nobody is home may simply have access to something rewarding and a history of finding good things there.

A sudden increase in food-seeking behavior deserves a closer look, particularly in an adult or older dog. Certain medications can increase appetite, and medical conditions such as diabetes or Cushing's disease can also affect hunger. If your dog has abruptly become much more interested in stealing food, especially alongside changes in thirst, urination, weight, or general behavior, talk with your veterinarian.

Why Is My Dog Eating Unusual Non-Food Items?

What if your dog is repeatedly eating hair, dust, dirt, leaves, carpet fibers, or other unusual materials? There's a difference between a dog who picks things up to investigate them, one who enjoys chewing on unusual objects, and one who actually swallows them. The distinction matters because repeated ingestion can point to medical or behavioral concerns.

Repeatedly eating non-food substances is sometimes called pica. It can be associated with gastrointestinal problems, other medical conditions, or behavioral factors. Stress can influence what a dog chooses to eat, and illness can also contribute to changes in eating behavior. If your dog has developed an unusual appetite for non-food materials, particularly if the behavior is new or becoming more frequent, a veterinary evaluation is a good place to start.

Why Does My Dog Chew Doors, Windows, or Walls?

Chewing or scratching at doors, windows, doorframes, and other barriers is worth investigating separately. A dog experiencing separation-related distress may direct their behavior toward an exit, but a dog who sees people or animals outside may also scratch, bite, or jump at a window or door. Some dogs become frustrated by confinement or try to reach something on the other side of a barrier.

Pay attention to when the destruction happens. Does your dog chew at the door only when home alone, or does it happen when people or animals are moving around outside? A dog reacting to a squirrel through the window may be motivated by something entirely different from a dog experiencing separation-related distress. Video footage can help us understand what's happening, especially when the behavior occurs while nobody is home.

Dogs experiencing separation-related distress may go through periods of intense activity, followed by exhaustion or brief periods of rest, before becoming distressed again. Chewing or scratching at exits can be part of that pattern, but destruction alone doesn't establish separation anxiety. If your dog is already showing signs of distress when left alone, the priority is to prevent further episodes while you work toward understanding and addressing the problem, rather than leaving them alone to see how the behavior unfolds.

If your dog becomes destructive while home alone, I've written more about how to distinguish separation anxiety from other alone-time behavior problems.

What Does Your Dog Do After Stealing Something?

This is one of my favorite questions to ask because the behavior doesn't end when the dog picks something up. Imagine four dogs who all steal the same sock. One immediately brings it to their person and stands nearby until someone notices. Another grabs the sock, looks directly at their person, and runs away as soon as someone approaches. A third quietly carries it to their bed and begins chewing, perfectly happy entertaining themselves. The fourth disappears under the bed and becomes tense or growls when someone approaches.

The first two dogs may have learned that taking objects is a reliable way to get people interacting with them. The third may enjoy chewing, while the fourth may be worried about having the sock taken away. We'd want to observe these dogs in other situations before deciding what's motivating them, but we're already learning a lot more than we would from simply knowing they steal socks.

How Your Response Shapes What Your Dog Learns

When investigating stealing, we also need to consider what happens afterward and how our responses influence what the dog learns. In behavior analysis, we call what follows a behavior the consequence. Consequences can change how likely a behavior is to happen again.

Imagine your dog picks up a remote control. You immediately stop what you're doing, call their name, walk toward them, and ask them to drop it. Maybe they run away, so you follow. You're simply trying to retrieve something valuable before it gets damaged, but your dog may be enjoying every second of the interaction.

Some dogs learn that picking up particular household objects reliably produces attention, movement, conversation, or a game of chase. If your dog has trouble getting your attention while you're working, they may discover that stealing a shoe works much better than quietly lying on their bed.

Punishment can create a very different learning history. If approaching a dog who has something frequently leads to scolding, having the object forcibly removed, or an unpleasant confrontation, the dog may begin retreating, hiding objects, swallowing them quickly, or becoming defensive when someone approaches.

Not every consequence involves another person. A dog who enjoys shredding cardboard may continue doing it simply because tearing things apart is rewarding. Whether the behavior is maintained by social interaction or by the activity itself will influence what we do about it.

When Stealing Things Turns Into Resource Guarding

Some dogs take an object and then become uncomfortable when people approach. You may see them carry items under furniture, retreat into corners, lower their head over an object, freeze, growl, snarl, or attempt to bite when someone reaches toward them. These behaviors may indicate that the dog is concerned about losing access to something they value.

Resource guarding isn't the same as stealing, and a dog who runs away with a sock isn't automatically guarding it. We need to consider body language, what the dog has learned about people approaching or taking objects, and how their behavior changes when someone comes closer. A dog who happily invites you to chase them may be having a very different experience from one who retreats because they expect a confrontation.

If your dog shows guarding behavior, I wouldn't recommend repeatedly testing whether they'll surrender objects, physically taking things away, or punishing growling. Those approaches can increase conflict and make guarding worse. Managing access to objects, reducing opportunities for confrontation, and developing a thoughtful behavior modification plan are better starting points. You can read more in my article on resource guarding in dogs and what to do about it.

What Can Your Dog's Stealing Behavior Tell You?

By looking at the circumstances surrounding stealing, you may begin to notice patterns that weren't obvious when you were focused on retrieving whatever your dog had taken. Consider what happened just before the behavior, what your dog's day looked like, what they chose to take, and what they did afterward. Your own response, along with the dog's previous experiences, can also help explain why the behavior keeps happening.

A young dog who regularly dismantles paper and cardboard while entertaining themselves may simply enjoy shredding. A dog who picks up your belongings as soon as you stop interacting with them may have learned that stealing gets your attention. A dog who becomes destructive around exits when left alone warrants a closer look at separation-related distress, while a dog who retreats or becomes defensive with stolen objects may be concerned about losing them.

These are starting points for investigating the behavior, not diagnoses. We may need to observe the dog in different circumstances, review video, or look at their learning history to determine which explanations are most likely. And it's entirely possible for more than one factor to be involved. A dog might enjoy chewing shoes and have also learned that taking one starts an exciting game with their person.

Understanding what maintains the behavior helps us decide what kind of support the dog needs. Sometimes that means providing suitable opportunities to carry, chew, or shred. Other situations may call for changes in how people respond, reducing access to certain objects, veterinary care, or a behavior modification plan addressing anxiety or resource guarding.

When a dog has taken something dangerous, safety comes first. Avoid turning retrieval into a confrontation, especially if your dog guards objects or tends to swallow them when approached. If you suspect your dog has swallowed something toxic, sharp, or potentially obstructive, contact your veterinarian or an emergency veterinary service promptly.

The next time your dog steals something, consider what the behavior might be telling you. A missing sock might be the beginning of a game, an enjoyable chewing opportunity, or part of a more complicated behavioral pattern. Looking at the full picture gives us a better chance of understanding which one we're dealing with.
