As a pet owner in Sydney, you’ve likely experienced the frustration of your dog digging up the garden, chewing through shoes, or causing chaos around the house. While these behaviours can be annoying, they’re often linked to instincts or unmet needs.
From boredom and anxiety to lack of exercise, understanding the root causes of your dog’s destructive behaviour is the key to solving the problem effectively. Breed-specific traits and age-related factors can also play a role. In this guide, we’ll explore the reasons behind your dog’s actions and offer practical solutions to help curb destructive habits, ensuring a happier and more harmonious home for both of you.

Common Reasons Dogs Destroy Things
Understanding why dogs engage in destructive behaviour is essential for addressing the issue effectively. By identifying the root causes, pet owners can implement strategies to prevent further destruction and promote a healthier, happier environment for their furry friends. Below are the most common reasons why dogs may destroy things, and what you can do to prevent it.
Boredom or Lack of Stimulation
Dogs, just like people, can get restless when their minds and bodies are not challenged. If left unchecked, boredom can quickly turn into destructive behaviour.
- Mental Stimulation: Dogs need puzzles, problem-solving games, and interactive toys to keep their minds engaged. Lack of mental challenges can lead them to chew on furniture, shoes, or even dig through trash for entertainment.
- Physical Activity: Regular exercise is crucial. Taking your dog for walks, playing fetch, or having playtime in a secure yard helps burn off excess energy. A well-exercised dog is less likely to engage in destructive behaviours.
By offering consistent physical and mental stimulation, your dog is more likely to direct its energy in positive ways.
Separation Anxiety
For many dogs, being left alone triggers anxiety, leading to destructive habits as a way of coping with the stress of isolation.
- Signs of Separation Anxiety: If your dog exhibits distress behaviours, like excessive barking, drooling, or destruction that only happens when you leave, it may be suffering from separation anxiety.
- Managing Separation Anxiety: Gradual desensitisation—getting your dog used to being alone slowly—can help. Additionally, comfort items like a blanket with your scent, or interactive toys, can provide comfort while you're away. Seeking professional help from a veterinarian or trainer can also help in severe cases.
Taking steps to address separation anxiety can significantly reduce stress-related destruction.
Teething (in Puppies)
Puppies, much like babies, go through a teething phase that drives them to chew on anything they can get their paws on.
- Providing Appropriate Chew Toys: Supply your puppy with a variety of safe and engaging chew toys. Items like rubber bones or frozen teething rings can offer relief from sore gums and prevent them from chewing on inappropriate objects.
- Puppy-Proofing Your Home: Keep valuable or delicate items out of your puppy’s reach during this stage. Supervise them closely, especially in the early stages, to ensure they don’t chew on harmful or valuable items.
Understanding that teething is a normal developmental stage can help you manage your puppy's chewing habits.
Instinctual Behaviour
Certain breeds are more inclined to dig or chew due to their natural instincts. These behaviours are often linked to their history as hunters, diggers, or retrievers.
- Breeds Prone to Digging and Chewing: Breeds like Terriers (known for tunnelling) and Retrievers (who love to carry and chew) may be more inclined to dig or chew.
- Channelling Instincts Positively: Encourage these instincts in positive ways by creating designated digging areas, such as a sandbox, or offering interactive toys to fulfil their need to chew.
By understanding your dog's breed traits, you can provide the appropriate outlets to prevent destructive behaviours.
Attention-Seeking
Sometimes, dogs destroy things to get attention from their owners. Even negative attention can be reinforcing if it’s the only way a dog knows to get a reaction.
- Ignoring Negative Behaviour: Avoid giving attention when your dog is misbehaving. By doing so, you don’t reinforce the negative behaviour.
- Positive Reinforcement: Reward calm and well-behaved actions. Providing praise and treats when your dog chooses to chew on their toys or relax will encourage them to engage in these behaviours more often.
By reinforcing positive actions, you can redirect your dog’s focus to more appropriate ways of gaining attention.
Lack of Training or Boundaries
Without proper training, dogs may not know what’s acceptable to chew or destroy. Clear boundaries and consistent rules are essential for a well-behaved dog.
- Establishing Boundaries: Use consistent commands and clear rules for what is off-limits. Reinforce good behaviour with treats and praise.
- Professional Training: If your dog continues to destroy things despite training, it might be time to seek professional help. Trainers can work with your dog on specific behavioural problems and help set clear boundaries.
Training and boundaries are crucial for helping your dog understand what’s acceptable behaviour.
Fear or Stress
Environmental changes, such as loud noises, moving house, or the introduction of new people, can cause stress or fear in dogs, leading to destructive actions.
- Identifying Triggers: Pay attention to what might be causing your dog’s stress. It could be construction noise, unfamiliar visitors, or changes in your routine.
- Creating a Safe Space: Set up a quiet, comfortable retreat where your dog can go to feel safe. This can help reduce anxiety-driven destruction and give your dog a place to relax.
Providing a calm environment can help reduce fear-induced destructive behaviour.

How to Tell What’s Causing the Behaviour
Understanding the underlying reasons behind your dog’s destructive behaviour, like digging, chewing, or destroying things, is key to effectively addressing the issue. With careful observation and analysis, you can identify the triggers and take appropriate action. Here’s a guide to help you determine what might be causing your dog’s unwanted behaviours.
Track When and Where Destruction Occurs
Timing and Location
Start by keeping track of when and where the destructive behaviour occurs. Understanding the context of the behaviour can provide important clues:
- When: Does your dog chew furniture when left alone, or does it only happen during certain hours, like at night? Some dogs may engage in destructive behaviour when they feel anxious or bored.
- Where: Does your dog chew on shoes, or do they prefer digging in the garden? Identifying specific areas of destruction can help determine if environmental factors are at play.
Environmental Factors
Look around for environmental triggers that could be influencing your dog’s actions. Consider these:
- Specific objects or areas: Is there a particular object your dog always targets, like a specific piece of furniture, a pair of shoes, or the garden?
- Distractions: External factors such as construction noise, storms, or other pets in the home might trigger unwanted behaviours. Understanding the surrounding environment helps pinpoint what’s causing the disruption.
Look for Patterns
Behavioural Patterns
Dogs are creatures of habit. Identifying when these behaviours tend to happen—like after being alone or right after a walk—can offer insight into whether it’s an emotional or physical need that's being overlooked.
- Destruction after being alone: If your dog only destroys things after being left alone for long periods, this could indicate separation anxiety.
- Post-exercise destruction: Does your dog engage in destructive behaviour after a walk or play session? This could be a sign that they have excess energy that they are unable to self-regulate.
Routine Changes
Evaluate any changes in your dog’s daily routine. These could include:
- Feeding times: Has your dog’s meal schedule changed recently? Dogs thrive on routine, and changes can cause stress.
- Exercise: A lack of regular exercise or a sudden change in activity level might lead to destructive behaviour as a way to burn off energy.
Consider Age, Breed, and Recent Changes
Age and Developmental Stages
Your dog’s age plays a huge role in their behaviour:
- Puppies: Chewing and exploring are natural for puppies, especially during the teething phase. If your puppy is chewing on things, it may be part of their development.
- Older dogs: If an older dog starts exhibiting destructive behaviour, this could indicate health problems, anxiety, or stress.
Breed-Specific Traits
Certain breeds are more prone to specific behaviours due to their instincts and history. For example:
- Digging breeds: Terriers, for instance, have a natural instinct to dig. If you own a breed known for this, they may be digging simply because it’s in their nature.
- Chewing breeds: Some breeds, like Retrievers, are naturally inclined to chew, which can lead to destroyed household items if not properly managed.
Understanding your dog’s breed-specific tendencies can help you manage their behaviour better.
Impact of Recent Changes
Changes in your dog’s environment or routine can cause stress, leading to destructive behaviour. Consider the following:
- New family members: The addition of a new baby, another pet, or a visitor can overwhelm your dog, triggering stress-induced behaviour.
- Relocation: Moving to a new home is a big change, and dogs can become anxious or confused in unfamiliar surroundings. This anxiety can lead to destructive habits.
Keep a Simple Behaviour Journal
Tracking Triggers and Frequency
Keeping a behaviour journal can help you track your dog’s actions over time and identify patterns more easily. Here’s what to document:
- Incidents of destruction: Record when and where your dog destroys things. This can help you pinpoint if certain times of day or situations trigger these behaviours.
- Frequency: Note how often the destructive behaviour occurs, which will help you determine the severity and regularity of the issue.
Recording Observations
In addition to documenting the timing and location, try to include other details, such as:
- Duration: How long does the destructive behaviour last? Is it a brief episode, or does it continue over an extended period?
- Preceding events: Was there anything that happened before the behaviour—such as a loud noise, a change in routine, or a stressful event—that could have contributed to your dog’s actions?
By keeping a detailed record, you’ll be better equipped to discuss the problem with a vet or behaviourist, who can help you develop a tailored solution.

Solutions and Prevention Tips
When your dog begins to dig, chew, or destroy household items, it’s essential to address the root cause of the behaviour. With the right strategies, you can manage and redirect these destructive habits, ensuring a happier and healthier environment for both you and your dog. Here are some effective solutions and prevention tips that can help:
Provide Enrichment
Toys and Puzzle Feeders
Keeping your dog mentally and physically engaged is one of the best ways to prevent destructive behaviour.
- Interactive Toys: Toys that dispense treats or require problem-solving can satisfy your dog's natural instincts, like foraging and hunting. Puzzle feeders are a great way to challenge your dog’s brain, providing both fun and stimulation.
- Toy Rotation: To maintain your dog’s interest, rotate their toys regularly. Having a variety of options will keep them excited and prevent them from becoming bored and looking for their own “entertainment,” like chewing on furniture or shoes.
Daily Walks and Play
Exercise is a must for maintaining a balanced dog, both mentally and physically.
- Tailored Walks: Every dog has unique exercise needs based on their breed, age, and energy level. Ensure your dog gets at least one walk daily. For high-energy dogs, you might need longer or more frequent walks.
- Playtime: Incorporate fun play sessions, like fetch, tug-of-war, or agility exercises. These activities help burn off excess energy and provide positive outlets for their excitement, reducing the likelihood of destructive behaviour.
Training and Redirection
Teach What is Acceptable to Chew or Dig
Consistency in training is crucial. Every family member should reinforce the same rules to ensure your dog understands what’s expected.
- Positive Reinforcement: Reward your dog with treats and praise when they chew on appropriate items like chew toys or bones. Make sure to redirect their focus when they start to chew on furniture or other inappropriate objects.
- Consistency: All household members must reinforce the same rules. Consistent training ensures your dog understands what’s acceptable and what isn’t.
Puppy-Proofing Your Home
Limit Access to Temptations
Prevent accidents and destruction by puppy-proofing your home. Use baby gates or crates to limit your puppy’s access to trouble spots, especially when they’re unsupervised.
- Restrict Access: Use baby gates or crates to keep your dog away from certain rooms or areas in the house. This is particularly helpful for puppies or dogs prone to chewing on furniture or household items.
- Store Items Out of Reach: Ensure that valuable or hazardous items, such as shoes, electrical cords, or cleaning supplies, are kept out of your dog's reach. This proactive approach helps prevent destruction before it starts.
Address Separation Anxiety
Gradual Desensitisation and Calming Routines
Destructive behaviour often arises from separation anxiety, particularly if your dog is distressed when left alone.
- Desensitisation: Start by leaving your dog alone for short periods, gradually increasing the duration as they become more comfortable being on their own. This helps them adjust without feeling stressed or anxious.
- Calming Routines: Create soothing routines to help calm your dog when you’re away. Leave behind a worn piece of clothing with your scent, or play calming music to ease their anxiety. These small steps can make a big difference in reducing destructive behaviours linked to separation anxiety.
Create a Safe Digging Zone (for Diggers)
A Designated Digging Spot in the Yard
For dogs that have a strong instinct to dig, redirecting their digging into a designated area can prevent damage to your garden or yard.
- Choose a Spot: Select a specific area in your yard for your dog to dig in. Bury toys or treats in this spot to encourage them to dig there.
- Reinforce Good Behaviour: Praise and reward your dog when they dig in the designated spot. This positive reinforcement will help them associate digging with a safe, appropriate area rather than your flowerbeds or garden.
Vet Check if Behaviour Is Sudden
Rule Out Pain, Discomfort, or Illness
If your dog suddenly starts exhibiting destructive behaviour, it’s essential to consult a veterinarian to rule out underlying health problems.
- Health Concerns: Sudden changes in behaviour, such as increased chewing or digging, can be a sign of pain or illness. A thorough vet examination can help identify any medical issues, from dental pain to gastrointestinal problems.
- Early Intervention: Addressing any health concerns early can help alleviate behavioural issues and ensure your dog’s overall well-being.
In conclusion, understanding the root causes of your dog’s destructive behaviour and taking proactive steps to address them can lead to a more peaceful and enjoyable life for both you and your furry companion. Whether it's providing mental stimulation, offering appropriate dog behaviour training, or creating a safe environment for natural instincts, there are plenty of effective strategies to redirect these behaviours. Remember, consistency and patience are key in helping your dog thrive.
