How to Stop Destructive Chewing in Puppies: Causes and Solutions

You walk into the living room and discover that your puppy has eaten the corner of your couch. Not nibbled. Eaten. The cushion has a hole the size of a softball, there is stuffing from one end of the room to the other, and your puppy is sitting in the middle of the wreckage looking extremely pleased with themselves.

Or maybe it was your shoes. Your remote control. Your child's favorite stuffed animal. The baseboard molding. The leg of a dining room chair that has been in your family for three generations.

Destructive chewing is one of the most common reasons puppies are surrendered to shelters. It is also one of the most preventable problems in all of dog training, once you understand why it happens and stop expecting a puppy to behave like a small adult dog.

Why Puppies Chew: The Four Types

All chewing is not the same. The cause determines the solution. A teething puppy needs different help than an anxious puppy, and both need different help than a bored puppy. Misidentifying the cause leads to solutions that do not work.

Type 1: Developmental Chewing (Teething)

What it is: Your puppy is chewing because their mouth hurts and chewing provides relief, exactly like a teething human baby who gnaws on everything in reach.

The teething timeline:

• 3 to 4 weeks: Baby teeth (deciduous teeth) begin erupting. 28 baby teeth total.
• 3 to 4 months: Baby teeth start falling out. You may find tiny teeth on the floor or notice bloody spots on chew toys. This is normal.
• 4 to 5 months: The most intense chewing phase. Adult premolars and molars are pushing through the gums. This is painful.
• 6 to 7 months: Most adult teeth have erupted. 42 permanent teeth total. Chewing intensity begins to decrease.
• 7 to 12 months: Chewing remains elevated above adult baseline but is driven more by habit and exploration than pain.

How to identify it: Teething chewing is focused on texture. Puppies in the teething phase seek out objects that provide counter-pressure against sore gums: hard objects for back-teeth pain, soft/flexible objects for front-teeth discomfort. The chewing has a rhythmic, grinding quality rather than frantic shredding.

The fix:

Provide appropriate chew outlets that feel good on sore gums.

• Frozen items: Wet a washcloth, twist it, and freeze it. The cold and texture provide excellent teething relief. Freeze rubber Kongs stuffed with peanut butter or banana. Freeze carrots (large pieces only — they should be too big to swallow whole).
• Rubber chew toys: Textured rubber toys designed for teething puppies provide the counter-pressure that relieves gum pain. Look for toys labeled for the puppy's size and chewing strength.
• Rotate toys: A chew toy that sat in the same spot for a week becomes boring. Pick up half your puppy's toys and rotate them every 2 to 3 days. The "new" toys become interesting again.

What to expect: Teething chewing is self-limiting. It peaks between 4 and 6 months and decreases significantly by 7 to 8 months. Your job during this window is to provide enough appropriate outlets that your furniture is less appealing than the alternatives.

Type 2: Exploratory Chewing

What it is: Puppies explore the world through their mouths. They do not have hands to pick things up and examine them. Chewing is how a puppy investigates texture, density, taste, and structural integrity of objects in their environment. This is cognitively normal and developmentally important.

How to identify it: Exploratory chewing is not focused on one item. The puppy samples everything: a shoe, then a book, then a plant, then a chair leg. They mouth objects briefly, carry things around, and move on. The body language is curious and relaxed, not frantic.

The fix:

You cannot and should not try to eliminate exploratory mouthing entirely. Instead, manage the environment and redirect.

• Puppy-proof ruthlessly. If it is on the floor and it is not a dog toy, it will be chewed. Pick up shoes, children's toys, remote controls, phone chargers, books, and anything else within your puppy's reach. This is the single most effective thing you can do. Complaining that your puppy chewed your shoes while your shoes were on the floor next to the puppy is like complaining that a toddler colored on the walls when you left them alone with markers.
• Redirect immediately. When you catch your puppy chewing something inappropriate, do not yell. Calmly take the item away and immediately offer an appropriate chew toy. When they take the toy, praise them. This is a swap, not a punishment.
• Supervise or confine. When you cannot actively watch your puppy, confine them to a puppy-proofed space: a crate, an exercise pen, or a gated room where there is nothing dangerous to chew.

Type 3: Anxiety-Based Chewing

What it is: Chewing driven by emotional distress, most commonly separation anxiety, noise phobias, or generalized anxiety. The chewing provides self-soothing through the release of endorphins (chewing is a natural calming mechanism for dogs).

How to identify it: Anxiety-based chewing has distinct characteristics that set it apart from other types:

• It occurs primarily or exclusively when the puppy is alone or during specific anxiety triggers (thunderstorms, fireworks)
• The destruction is intense and frantic: deep gouging, shredding to small pieces, targeting exit points (door frames, window sills, crate bars)
• The puppy may also be panting, drooling, pacing, or vocalizing
• The chewing is not redirected by the presence of appropriate chew toys. A frozen Kong sits untouched while the puppy destroys the door frame
• House soiling may accompany the chewing even in a house-trained puppy

The fix:

Anxiety-based chewing is a symptom. You must address the anxiety itself.

If the chewing is connected to separation anxiety, refer to a systematic desensitization protocol. If it is noise-related, work with your veterinarian on a noise phobia management plan that may include medication, counter-conditioning, and environmental management (white noise machines, interior rooms during storms).

Simply providing more chew toys will not fix anxiety-based chewing because the motivation is not boredom or oral needs. The puppy is in distress and the chewing is a coping mechanism.

Important: If your puppy is destroying their crate when left alone, stop crating them. A panicking puppy in a crate can break teeth on the bars, tear nails trying to dig out, and lacerate gums and paws on bent wire. Confine them to a puppy-proofed room instead and address the underlying anxiety.

Type 4: Boredom Chewing

What it is: A physically and mentally under-stimulated puppy who turns to chewing because there is literally nothing else to do. This is the canine equivalent of a bored teenager who picks at the wallpaper.

How to identify it: Boredom chewing typically happens during long periods of inactivity, targets a variety of objects (not just exit points), and the puppy seems relaxed rather than distressed. They are not anxious; they are unstimulated.

The fix:

• Increase physical exercise. A tired puppy chews less. Appropriate exercise for your puppy's age (see guidelines below) makes a significant difference.
• Increase mental stimulation. Puzzle feeders, snuffle mats, training sessions, and scent games provide cognitive enrichment that reduces the need for destructive entertainment.
• Feed meals from enrichment toys. Instead of a bowl, use a Kong, a Toppl, a snuffle mat, or a puzzle feeder. A puppy who spends 20 minutes working for breakfast has less need to chew the furniture afterward.
• Provide appropriate chew items. Long-lasting chews (detailed below) give the puppy a job and satisfy the oral need that chewing fulfills.

Exercise guidelines by age:

A common rule of thumb is 5 minutes of structured exercise per month of age, twice daily. A 4-month-old puppy gets two 20-minute walks. This is a rough guideline, not a rigid rule. Free play in a yard and sniff walks do not count against this limit, as they are self-regulated by the puppy.

Over-exercising a puppy can damage developing joints, especially in large and giant breeds. Avoid forced running, jumping from heights, and extended fetch on hard surfaces until growth plates close (12 to 18 months for most breeds, up to 24 months for giant breeds).

Puppy-Proofing: Management First, Training Second

Before any training begins, manage the environment. This is not lazy or cheating. It is the professional approach.

A puppy who never gets to practice destructive chewing on your belongings has no reinforcement history for it. Every time they successfully shred a shoe, the act of chewing is reinforced by the sensory pleasure it provides: the texture, the taste, the tearing sensation. You cannot unteach that reinforcement. You can only prevent it from accumulating.

Room-by-Room Checklist

Living room:

• Electrical cords: Cover with cord protectors or route behind furniture
• Remote controls, phones, game controllers: In drawers or on high shelves
• Throw pillows and blankets: Up and away when unsupervised
• Books and magazines: Shelves, not coffee tables
• Houseplants: Many are toxic to dogs. Move them up or out of the room entirely

Kitchen:

• Garbage: Behind a cabinet with a child lock, or in a closed pantry
• Cleaning products: Secured behind child-locked cabinet doors
• Food on counters: Pushed to the back or stored in cabinets

Bedroom:

• Shoes: In the closet, door closed
• Laundry: In a hamper with a lid. Socks and underwear are the most commonly ingested clothing items and can cause intestinal blockages
• Charging cables: Unplugged and stored when not in use

Bathroom:

• Toilet paper: On a high shelf or behind a closed door
• Medications: In a medicine cabinet, closed
• Trash can: Behind a closed door or with a locking lid

Garage/utility areas:

• Chemicals, antifreeze, fertilizers: On high shelves behind closed doors. Antifreeze is deadly to dogs and has a sweet taste they are attracted to.
• Tools, hardware, nails, screws: Enclosed storage

Enrichment Feeding: The Single Most Effective Daily Habit

If you do nothing else from this guide, do this: stop feeding your puppy from a bowl.

A puppy who eats their entire meal in 90 seconds from a bowl has consumed their calories but received zero mental stimulation from the process. A puppy who spends 20 to 30 minutes working their meal out of a puzzle feeder has engaged their brain, satisfied their foraging instinct, and has significantly less residual energy and boredom to direct at your furniture.

The Enrichment Feeding Hierarchy

Level 1 — Scatter feeding: Scatter kibble in the grass or on a snuffle mat. Engages nose work and foraging. Takes 5 to 10 minutes.

Level 2 — Stuffable toys: Pack a Kong or Toppl with kibble mixed with a small amount of wet food, yogurt, or peanut butter (xylitol-free). Freeze for added difficulty. Takes 10 to 30 minutes.

Level 3 — Puzzle feeders: Sliding, spinning, and lifting mechanisms that require problem-solving. Start with easy puzzles and increase difficulty as your puppy masters them. Takes 10 to 20 minutes.

Level 4 — DIY enrichment: Hide food in cardboard boxes, muffin tins covered with tennis balls, rolled-up towels. Rotate setups to maintain novelty. Takes 10 to 30 minutes.

Rotate between levels throughout the week. Variety keeps the enrichment engaging.

Safe Chew Items vs. Dangerous Ones

Not all chew items are created equal. Some are safe, some are controversial, and some are genuinely dangerous.

Safe and Recommended

• Rubber Kongs and similar toys: Nearly indestructible for most chewers, can be stuffed and frozen, dishwasher safe. Size up if your puppy is a powerful chewer.
• Bully sticks: Single-ingredient, fully digestible. Choose thick sticks for strong chewers. Use a bully stick holder to prevent swallowing the last inch.
• Yak chews (Himalayan cheese chews): Hard, long-lasting, and generally well-tolerated. When the piece gets small enough to swallow, microwave it for 30 to 45 seconds to puff it into a crunchy treat.
• Frozen carrots and sweet potatoes: Low-calorie, good for teething. Supervise to prevent large pieces from being swallowed.
• Rubber dental chews: Designed to be gnawed, not consumed. Good texture for gum massage during teething.

Controversial (Proceed With Caution)

• Rawhide: The main concern is digestibility. Rawhide does not break down easily in the stomach and can cause intestinal blockages if large pieces are swallowed. If you choose to offer rawhide, buy US-sourced, thick rolls (not thin chips that can be swallowed whole), and supervise closely. Many veterinary professionals recommend avoiding rawhide entirely.
• Antlers: Very hard and can fracture teeth, particularly the upper fourth premolars (the slab fracture). If you offer antlers, choose split antlers (softer inner marrow exposed) rather than whole antlers, and select a size appropriate for your dog. Remove the antler when it becomes small enough to fit entirely in the dog's mouth.
• Nylon bones: Some dogs enjoy them, but they can also fracture teeth due to their hardness. The general test: if you cannot indent it with your thumbnail, it is too hard for your dog's teeth.

Dangerous — Avoid

• Cooked bones: Cooking changes the molecular structure of bone, making it brittle. Cooked bones splinter into sharp fragments that can perforate the esophagus, stomach, or intestines. This is a veterinary emergency that can be fatal. Never give your puppy cooked bones of any kind — chicken, turkey, pork, beef ribs.
• Sticks from the yard: Splinter risk, mouth and throat punctures, intestinal obstruction if pieces are swallowed.
• Rocks: Some puppies develop a fixation on rocks. Rock chewing breaks teeth and ingestion can cause life-threatening intestinal blockage.
• Corn cobs: Cannot be digested and are a common cause of intestinal blockage requiring emergency surgery.
• Children's toys: Small parts, plastic that shatters, stuffing that causes blockages.
• Fabric items: Socks, underwear, towels. Fabric does not break down in the digestive tract and is a leading cause of foreign body obstruction in puppies.

Pica: When Chewing Becomes Eating Non-Food Items

Pica is the compulsive ingestion of non-food materials: rocks, dirt, fabric, plastic, paper, drywall. This is not normal exploratory chewing. It is a medical and behavioral condition that requires veterinary attention.

Medical Causes of Pica

• Gastrointestinal disorders (inflammatory bowel disease, malabsorption conditions, parasites)
• Nutritional deficiencies (rare with quality commercial diets but possible)
• Endocrine disorders (diabetes, Cushing's disease)
• Neurological conditions
• Anemia (iron deficiency can drive consumption of unusual substances)

Behavioral Causes of Pica

• Compulsive disorder (analogous to OCD, involving dysregulation of serotonin pathways)
• Anxiety (severe generalized anxiety can manifest as compulsive eating of non-food items)
• Attention-seeking (if previous episodes of eating non-food items resulted in significant human attention and interaction, even negative attention)

What to Do

If your puppy is consistently ingesting non-food items (not just mouthing or carrying them, but actually swallowing them), see your veterinarian immediately. Blood work, fecal examination, and potentially imaging are warranted. If medical causes are ruled out, a referral to a veterinary behaviorist is the next step.

Pica can be life-threatening. Intestinal foreign bodies are a surgical emergency, and repeated surgeries are costly and carry increasing risk.

What NOT to Do

Do Not Punish Your Puppy After the Fact

If you come home and find your couch destroyed, there is nothing productive you can do about the couch. Punishing your puppy at that moment teaches them nothing about chewing, because dogs do not connect consequences with events that happened hours or even minutes earlier. What the puppy learns is that your arrival home is sometimes scary and unpredictable. This can actually increase anxiety, which can increase anxiety-based chewing. It is a vicious cycle.

The guilty look your puppy gives you when you find the destruction is not guilt. It is fear. Studies published in Behavioural Processes demonstrated that the "guilty look" in dogs is a response to the owner's body language and tone of voice, not an indication that the dog associates their past behavior with the current consequences. Your puppy reads your angry face and posture and offers appeasement behaviors (tucked tail, lowered head, averted gaze) to diffuse the social threat. They are scared, not sorry.

Do Not Use Bitter Apple Spray as Your Only Solution

Bitter-tasting deterrent sprays can reduce chewing on specific items, and they have their place. But they do not address the underlying motivation. A puppy who is teething will find something else to chew. A bored puppy will find something unsprayed. An anxious puppy will chew through the taste. Deterrent spray is a supplement to management and training, not a replacement.

Do Not Take Away All Chew Options

Some owners react to destructive chewing by removing all chew items, reasoning that if the puppy cannot chew anything, they will stop chewing. This is like trying to stop a toddler from using their hands by removing all objects. The need does not go away. The puppy will find something to chew: your furniture, your drywall, their own paws.

Provide appropriate outlets. The goal is to channel the chewing instinct toward acceptable items, not to suppress it.

Do Not Rely on Physical Corrections

Scruff shakes, holding the puppy's mouth closed, and rubbing their nose in the damaged item are all punishment-based methods that the AVSAB explicitly advises against. They damage the human-dog relationship, increase anxiety, and do not teach the puppy what to do instead. A puppy who is afraid of you is not a puppy who has learned not to chew. They are a puppy who has learned to chew when you are not watching.

Realistic Timelines

Teething chewing (3 to 7 months): This is the most intense period. Expect peak destruction between 4 and 6 months. Significant improvement by 7 to 8 months. Manageable with appropriate chew outlets and puppy-proofing.

Exploratory chewing (8 weeks to 12 months): Decreases gradually as the puppy matures and learns household rules. Most puppies are reliably past exploratory chewing by 12 to 18 months with consistent management and redirection.

Boredom chewing: Resolves quickly (1 to 2 weeks) once enrichment, exercise, and mental stimulation are increased. Returns immediately if enrichment decreases.

Anxiety-based chewing: Timeline depends on the underlying anxiety. With appropriate treatment (behavior modification plus medication if indicated), improvement is typically seen within 4 to 12 weeks, but complete resolution may take months.

Pica: Highly variable. Medical causes may resolve quickly with treatment. Compulsive pica may require long-term management and medication.

When to See a Professional

Consult your veterinarian or a veterinary behaviorist if:

• Your puppy is ingesting non-food materials (pica), not just chewing them
• Chewing is destroying their teeth (broken, fractured, or worn teeth need veterinary dental care)
• Chewing is accompanied by other anxiety signs (panting, pacing, vocalization, house soiling when alone)
• The chewing seems compulsive: repetitive, trance-like, difficult to interrupt
• You have implemented management, enrichment, and redirection for 4 or more weeks with no improvement
• Your puppy has had or may need surgery for a foreign body obstruction

A veterinary behaviorist (DACVB) is the appropriate specialist for anxiety-based or compulsive chewing. A certified professional dog trainer (CPDT-KA) can help with management strategies and environmental enrichment plans for boredom and exploratory chewing.

Frequently Asked Questions

At what age do puppies stop chewing everything?

Most puppies show a significant decrease in destructive chewing between 7 and 12 months as teething ends and they mature. However, chewing as a behavior never stops entirely and should not. Adult dogs benefit from daily chewing for dental health, stress relief, and mental stimulation. The goal is not to eliminate chewing but to direct it toward appropriate items. By 18 to 24 months, most dogs with consistent training and enrichment have reliable household manners.

My puppy only chews my things, not my partner's. Why?

Your items smell more like you, and your puppy is most bonded to you. Objects saturated with your scent are comforting and interesting. This is actually a sign of healthy attachment, even though it is frustrating. Keep your personal items out of reach and provide a worn T-shirt in the puppy's crate or bed as an appropriate scent-comfort item.

Is it okay to give my puppy old shoes to chew on?

No. Puppies cannot distinguish between an old shoe you have designated as a toy and a new shoe you paid $150 for. They all smell like shoes. They all feel like shoes. By giving an old shoe as a chew toy, you are teaching your puppy that shoes are appropriate chew items. Provide items that are clearly different from household objects.

My puppy chews their own paws. Is that destructive chewing?

Paw chewing is usually not related to the destructive chewing described in this article. Common causes include allergies (the most frequent cause of paw chewing in dogs), yeast infections between the toes, foreign bodies (foxtails, splinters), contact irritants, and anxiety. If your puppy is chewing their paws to the point of redness, hair loss, or raw spots, see your veterinarian. Allergies in dogs typically manifest as skin and paw issues rather than the sneezing and watery eyes humans experience.

How do I know if my puppy swallowed something dangerous?

Signs of a foreign body obstruction include repeated vomiting, inability to keep water down, loss of appetite, lethargy, painful abdomen (crying when picked up or when the belly is touched), straining to defecate, and absence of bowel movements. If you suspect your puppy has ingested a non-food item and shows any of these signs, this is a veterinary emergency. Do not wait to see if it passes. Intestinal obstructions can become fatal within 24 to 48 hours without surgical intervention.
