Why Dogs Dig and Chew: Understanding Canine Behaviors
Discovering a destroyed couch, a yard covered with holes, or your favorite shoes in pieces can be incredibly frustrating. However, understanding why dogs dig and chew is the critical first step toward managing these common canine behaviors. Dogs don't engage in digging and chewing to be destructive—these are natural, instinctive behaviors serving important functions for dogs. By understanding the underlying motivations behind dog digging behavior and destructive chewing dogs, you can implement effective solutions for stopping dog chewing and addressing destructive dog behavior. This comprehensive guide explores the reasons dogs exhibit these behaviors and provides practical strategies for redirection and management.
Why Dogs Dig and Chew: Natural Canine Instincts
Why dogs dig and chew begins with understanding that these are completely normal behaviors rooted in canine evolution and instinct. Dogs aren't born understanding that your furniture is off-limits—they're following natural drives that served their wild ancestors well.
Evolutionary Roots of Digging
Digging is an ancient canine behavior. Wild dogs and wolves dig to create dens for shelter, to access food sources underground, to cool themselves by reaching cooler earth, and to mark territory. Even today's companion dogs retain these instincts. Your dog digging in your yard is expressing behavior bred into their DNA over thousands of years.
Natural Chewing Behaviors
Chewing serves multiple functions for dogs. Puppies chew intensely during teething as their baby teeth are replaced by adult teeth. Adult dogs chew to maintain healthy teeth and gums, to occupy themselves, to relieve stress, and to explore their world. Chewing is a self-soothing behavior that activates pleasure centers in a dog's brain.
The Difference Between Normal and Destructive
Normal digging and chewing directed toward appropriate items is healthy. A puppy chewing on appropriate toys, a dog digging in a designated sandbox, or adults chewing bones represent normal expressions of these drives. However, when these behaviors target your furniture, landscaping, or other inappropriate objects, intervention is needed.

Why Dogs Dig: Specific Causes and Motivations
Understanding specific reasons behind dog digging behavior helps address root causes effectively.
Seeking Comfort and Temperature Regulation
Dogs often dig to reach cooler earth on hot days. Digging creates a depression where cooler soil is accessible, helping regulate body temperature. This behavior is especially common in warm climates and during summer months. Dogs without adequate shade or cool resting areas dig to create their own cooling solutions.
Creating Dens for Security
Some dogs dig to create den-like spaces where they feel safe and secure. This behavior is more pronounced in anxious dogs or those without adequate shelter. The excavated area provides a comfortable, enclosed space that feels protective.
Boredom and Excess Energy
Dogs with insufficient exercise and mental stimulation often dig out of boredom. Digging occupies their time and expends energy. Dogs confined to yards without adequate activities frequently develop digging habits as self-entertainment.
Prey Drive and Hunting Behavior
Some dogs dig because they've detected rodents, insects, or other prey underground. The digging represents an instinctive hunting response. Terrier breeds, which were historically bred to dig for prey, show particularly strong digging drives.
Escape Attempts and Territorial Marking
Dogs may dig under fences attempting escape. Additionally, digging scatters soil and urine, which marks territory and communicates presence to other dogs. This territorial behavior often intensifies when dogs sense other animals nearby.
Medical Issues
Occasionally, excessive digging indicates medical problems. Skin allergies, parasites, or other dermatological issues cause itching that dogs attempt to relieve through digging. Any sudden increase in digging warrants veterinary evaluation.
Why Dogs Chew: Root Causes of Destructive Chewing Dogs
Understanding what drives destructive chewing dogs enables appropriate intervention.
Teething in Puppies
Puppy chewing peaks between 3-6 months when baby teeth are replaced by permanent teeth. Teething puppies experience sore, itchy gums and chew intensively seeking relief. This behavior is developmentally normal and typically decreases as adult teeth fully erupt.
Maintaining Dental Health
Adult dogs chew to keep teeth and gums healthy. Chewing action removes buildup, stimulates gums, and exercises jaw muscles. Dogs instinctively recognize chewing's dental benefits, making it a consistent behavior throughout their lives.
Anxiety and Stress Release
Dogs experiencing anxiety or stress often chew compulsively. The repetitive action and focus required for chewing provides calming effects. Dogs under stress from separation anxiety, environmental changes, or other factors often chew excessively.
Boredom and Lack of Stimulation
Insufficient mental and physical exercise leads to destructive chewing. Bored dogs occupy themselves by exploring their environment—often by chewing. Dogs left alone without adequate enrichment commonly develop destructive chewing habits.
Seeking Attention
Dogs learn that chewing inappropriate items gets owner attention. Even negative attention—scolding or chasing—rewards the behavior. Once chewing succeeds in gaining attention, the dog repeats it.
Exploring and Investigating
Puppies especially explore their world through their mouths. Chewing helps puppies understand their environment, test object durability, and discover what's edible. This exploratory behavior is developmentally normal in young dogs.

Destructive Dog Behavior: Identifying the Underlying Cause
Determining whether your dog's behavior reflects normal expression of instincts or problematic destructive behavior requires honest assessment.
Assessment Questions
Ask yourself:
- When does the destructive behavior occur (during your absence, when anxious, when bored)?
- Is behavior focused on specific items or scattered across multiple objects?
- Does your dog have adequate exercise and mental stimulation daily?
- Are appropriate outlets for these behaviors available?
- Is the behavior worsening or remaining stable?
- Has anything changed in your dog's life recently?
Your answers reveal patterns indicating root causes and appropriate interventions.
Differentiating Between Causes
Boredom-related: Occurs predictably when left alone; scattered destruction; often accompanied by other boredom signs.
Anxiety-related: Intensifies during stressful times; often focused on barriers or escape routes; accompanied by other anxiety signs.
Normal development: Puppy chewing during teething; occurs throughout day; improves naturally as permanent teeth erupt.
Attention-seeking: Occurs when owner is home and available; intensifies with owner presence; stops when attention is provided.
Stopping Dog Chewing: Effective Management Strategies
Once you understand why dogs dig and chew, implement targeted solutions for stopping dog chewing and destructive dog behavior.
Provide Appropriate Outlets for Chewing
Supply quality chew toys: Invest in durable chew toys, bones, and puzzle toys designed for dogs. Rotate toys to maintain interest. Freeze toys with peanut butter or treats for extended engagement.
Appropriate chew items include:
- Rubber Kong toys (fillable with treats)
- Nylon chew bones and toys
- Natural rawhide alternatives
- Rope toys for supervised play
- Puzzle toys dispensing treats
- Appropriate raw or cooked bones
Manage Environment and Prevent Access
Remove temptation by restricting access to inappropriate items. Close doors to off-limit rooms, use baby gates, store personal items securely, and keep shoes and clothing put away. Prevention is simpler than correcting after the fact.
Redirect to Appropriate Alternatives
When you catch your dog chewing inappropriately, immediately redirect to approved toys. Remove the inappropriate item calmly, then present an approved chew toy with enthusiasm. Reward your dog for accepting the redirected item.
Increase Exercise and Mental Stimulation
Ensure adequate daily exercise appropriate for your dog's age and breed. Most dogs need 30-60 minutes daily; some need more. Combine physical exercise with mental stimulation through training, puzzle toys, and interactive games.
Don't Punish Destructive Behavior
Never punish destructive chewing or digging discovered after the fact. Your dog doesn't connect past misbehavior with current punishment. Punishment creates fear and anxiety, potentially worsening destructive behavior. Only redirect behavior caught in the moment.
Managing Dog Digging Behavior: Practical Solutions
Addressing dog digging behavior requires understanding whether your dog digs from boredom, temperature regulation, escape attempts, or prey drive.
Provide Designated Digging Area
Create a specific area where digging is permitted and encouraged. Some dog owners use sandboxes, kiddie pools filled with sand, or designated yard sections. Bury toys or treats in the approved area to encourage digging there rather than elsewhere.
Ensure Adequate Shade and Cooling
Provide shaded resting areas, doghouses, or covered spaces where your dog can escape heat. Access to cool water and appropriate shelter often reduces dig-induced cooling attempts.
Increase Exercise and Enrichment
Combat boredom-related digging with more exercise, playtime, and mental challenges. Bored dogs dig less when adequately stimulated. Interactive toys, training sessions, and varied activities reduce idle digging.
Supervise Outdoor Time
When possible, supervise yard time. This allows you to redirect digging attempts and encourage approved activities. Extended unsupervised yard time often enables habitual digging.
Secure Fence Lines
If your dog digs attempting escape, secure fence lines by burying barriers or extending fencing underground. Address underlying causes of escape attempts—fear, anxiety, or attraction to external stimuli—with training and management.
When Destructive Dog Behavior Indicates Underlying Issues
While why dogs dig and chew usually reflects normal instincts, sometimes excessive behavior indicates problems requiring professional intervention.
Signs of Compulsive Behavior
If your dog engages in repetitive, compulsive digging or chewing despite having appropriate outlets and adequate exercise, consult a veterinary behaviorist. Some dogs develop obsessive-compulsive behaviors requiring professional evaluation and treatment.
Anxiety-Related Destructiveness
Destructive behavior intensifying during specific times or situations may indicate anxiety. Separation anxiety, thunderstorm phobia, or general anxiety manifesting as destructive behavior requires specialized intervention.
Medical Causes
Sudden increase in digging or chewing may indicate dermatological issues, parasites, pain, or other medical conditions. Veterinary evaluation should precede behavior modification when destructive behavior represents a significant change.
Preventing Destructive Dog Behavior in Puppies
Establishing good habits early prevents destructive dog behavior from becoming entrenched.
Early Socialization to Appropriate Items
Introduce puppies to approved chew toys early. Make these toys consistently rewarding and available. Puppies that learn early to direct chewing toward appropriate items are less likely to develop destructive habits.
Managing Puppy Environment
Puppy-proof your home immediately. Restrict access to inappropriate chew items and designated areas. This prevents puppies from learning that human items are acceptable chew targets.
Providing Outlets During Peak Teething
During teething months (3-6 months), provide extra appropriate chew toys, especially frozen ones that soothe sore gums. This redirects teething intensity toward approved items.
Consistent Training and Redirection
Catch puppies early when they attempt inappropriate chewing. Redirect consistently and reward approved choices. Early consistent training prevents habits from forming.
Conclusion: Working With Natural Instincts
Understanding why dogs dig and chew transforms frustration into compassionate problem-solving. Your dog isn't being deliberately destructive—they're expressing natural instincts and attempting to meet physical and psychological needs. By recognizing underlying causes and providing appropriate outlets, you address behavior at its source rather than simply punishing symptoms.
Managing dog digging behavior and destructive chewing dogs requires patience, consistency, and often some creative problem-solving. Providing appropriate toys, adequate exercise, mental stimulation, and supervision significantly reduces destructive dog behavior. Most dogs respond well when their needs are met and proper alternatives are readily available.
Remember that stopping dog chewing and digging isn't about suppressing natural instincts—it's about redirecting them toward appropriate expressions. A dog that's allowed to chew approved toys and dig in a designated area is still expressing these natural behaviors while protecting your property.
Start today by assessing your dog's situation, identifying root causes, and implementing targeted solutions. Your consistent effort to understand and redirect these behaviors creates a happier dog and a more peaceful household. With patience and appropriate management, destructive dog behavior can be substantially improved or eliminated entirely.
