Chewing is a natural and essential behavior for dogs, but it can intensify during different life stages or under certain circumstances. Understanding the root cause why do dogs chew everything – is the first step to managing it effectively. Here are the most common reasons your dog might be turning your belongings into chew toys, and what you can do about it:
1. Puppy Teething Troubles
Just like human babies, puppies go through a teething phase, replacing their needle-sharp baby teeth with adult ones. This typically starts around 3-4 months of age and can last for about three months. During this period, their gums can be itchy and sore, making them strongly desire to chew on anything to relieve the discomfort.
What to do:
- Provide safe and appealing chew toys.
- A special teething toy, cooled in the freezer, can offer soothing relief to their gums.
- Rubber toys stuffed with frozen yogurt or peanut butter (ensure it’s xylitol-free for safety) are also excellent options.
2. Boredom or Lack of Mental/Physical Stimulation
Adult dogs often resort to chewing, especially if they’re bored or not getting enough physical and mental exercise. A tired dog is usually a well-behaved dog!
What to do:
- Go beyond short potty breaks. Engage your dog in longer, more stimulating walks.
- Ensure a balance of physical and mental activity. This includes running, playing fetch, training sessions with simple commands, and scent games like “find the treat.”
- Use puzzle feeders or treat-dispensing toys to make mealtime a mentally engaging activity.
3. Stress or Over-Excitement
Chewing has a self-soothing effect for dogs. They might chew due to stress caused by changes in their environment (like moving to a new home), the introduction of new people or pets, or loud, unfamiliar noises (thunderstorms, fireworks).
What to do:
- Offer safe chewing alternatives: provide durable chew toys or long-lasting natural chews.
- Gradually introduce your dog to new situations in a controlled, positive manner.
- Ensure your dog has a quiet, secure “den” or resting place where they can feel safe and unwind.

4. Separation Anxiety When Left Alone
If you come home to damaged items after being out, it might be more than just boredom. This could be a sign of separation anxiety, where your dog experiences distress when left by themselves.
What to do:
- Gradually accustom your dog to alone time. Start with very short periods (5-10 minutes) and slowly increase the duration as they become comfortable.
- Leave special, high-value chew toys specifically for when you’re gone to redirect their attention.
- Never punish your dog after the fact. They won’t connect the punishment to what they did hours ago; it will only worsen their anxiety. Focus on positive reinforcement and prevention.
5. Natural Instincts and Breed Tendencies
Some breeds, particularly hounds, terriers, and retrievers, have a stronger innate desire to chew. It’s simply part of their genetic makeup, and you won’t be able to completely eliminate this behavior.
What to do:
- Channel this natural instinct into safe and appropriate outlets.
- Provide a variety of appropriate chews: consider dried meats, bully sticks, antlers, or coffee wood chew sticks (ensure they are reputable and safe for dogs).
What About Chewing Sticks and Branches Outdoors?
It might seem harmless when your dog grabs a stick or piece of bark on a walk, but it can actually be quite dangerous.
Potential Risks:
- Splinters can get lodged between teeth, injure gums, or puncture the throat.
- Swallowed pieces of wood can cause internal injuries or blockages in the gastrointestinal tract, potentially requiring emergency surgery.
What to do:
- Always carry safe, appropriate chew toys with you on walks as an alternative.
- Engage your dog in exciting games and activities during your outings to keep their attention focused away from sticks.
Is It a Sign of Vitamin or Mineral Deficiency?
There is no scientific evidence to suggest that destructive chewing is a direct sign of vitamin or mineral deficiency. If your dog is eating a balanced, high-quality dog food, there’s generally no need to worry. However, a sudden, drastic change in chewing behavior, especially in an adult dog, could indicate an underlying health issue. In such cases, it’s always best to consult your veterinarian to rule out any medical problems.
First Aid for Destructive Chewing
- Substitute & Redirect: Replace any inappropriate items your dog is chewing with safe and enticing chew toys. When you catch them chewing something they shouldn’t, firmly say “no,” remove the item, and immediately offer an appropriate chew toy. Praise them when they chew on the correct item.
- Channel Energy: Ensure your dog gets plenty of active play and training sessions throughout the day to burn off excess energy.
- Dog-Proof Your Home: Block access to dangerous items like electrical cords, household chemicals, and toxic plants. Use baby gates or close doors to restrict access to “off-limits” areas.
- Put Valuables Away: Don’t leave tempting items, especially natural leather shoes or remotes, within your dog’s reach.
- Create a Calm Environment: Maintain a stable and calm atmosphere at home, avoiding shouting or excessive stress, which can contribute to anxiety-related chewing.
- Teach, Don’t Punish: Remember, the key is not to scold or punish your dog after the fact, but rather to teach them what is acceptable to chew on and guide their natural instincts.
Remember: Dogs need to chew – it’s not a misbehavior, but a fundamental need. Your role as a responsible owner is to make this process safe, positive, and beneficial for them!
