Why Does My Dog Chew on Metal?

Have you ever wondered why your furry friend seems to have a strange fascination with chewing on metal objects? It’s a common behavior exhibited by dogs, but what drives them to do it? In this article, I will explore the reasons behind why dogs chew on metal and offer some insights into how you can address this behavior. So, if you’ve ever found your dog gnawing on metal items around the house, grab a cup of tea and let’s uncover the mystery behind this peculiar habit together.

Understanding Dog Chewing Behavior

As a dog owner, it’s important to understand why your furry friend engages in certain behaviors, such as chewing. Chewing is a natural instinct for dogs and serves various purposes, including exploration, alleviating teething discomfort, and even dental health. In this article, I will delve into the reasons behind why dogs chew on metal and explore potential explanations such as dental health issues, nutritional deficiencies, behavioral problems, anxiety and stress, as well as boredom and lack of mental stimulation.

Natural Instincts

Dogs have a natural instinct to chew, which can be traced back to their wolf ancestors. Wolves often chew on bones and other items to keep their teeth clean and sharp, as well as to relieve boredom. This instinct has been passed down to domesticated dogs, leading them to seek out objects to chew on, including metal. It’s important to remember that chewing is a normal behavior for dogs, but it’s crucial to identify the underlying reasons when they chew on metal to ensure their well-being and safety.

Exploration and Curiosity

One possible reason why dogs chew on metal is out of curiosity and the desire to explore their surroundings. Dogs use their mouth as a way to investigate objects and learn about the world around them. When they come across metal objects, the unfamiliar texture and taste may intrigue them, leading to chewing behavior. It’s essential to provide alternative and appropriate chew toys to redirect their attention away from metallic objects and satisfy their exploration instincts.

Teething and Oral Discomfort

During the teething stage, which usually occurs between 3 to 7 months of age, puppies experience discomfort and soreness in their gums. Chewing on metal objects might provide them with some relief by applying pressure to their gums. The cold sensation of metal may also help soothe the discomfort caused by teething. Providing teething toys specifically designed for puppies can help alleviate their oral discomfort and prevent them from resorting to chewing on metal.

Potential Reasons for Chewing on Metal

While natural instincts, exploration, and teething can explain some instances of dogs chewing on metal, there are other potential reasons to consider. These include dental health issues, nutritional deficiencies, behavioral problems, anxiety and stress, as well as boredom and lack of mental stimulation. Let’s explore these possibilities further.

Dental Health Issues

Dogs, like humans, can develop dental health issues that may contribute to their chewing behavior. Dental problems such as gum disease, tooth decay, or misalignment can cause discomfort, pain, and inflammation in the mouth. Chewing on metal objects might be an attempt to alleviate this discomfort. Regular dental check-ups by a veterinarian and proper dental care can help prevent such issues and reduce the likelihood of dogs seeking relief through metallic chewing.

Nutritional Deficiencies

Another potential reason why dogs chew on metal is nutritional deficiencies. Dogs require a balanced diet to meet their nutritional needs, including essential vitamins and minerals. When they lack certain nutrients in their diet, they may exhibit abnormal behaviors like chewing on non-food items, known as pica syndrome. Metal chewing could be a sign of pica syndrome caused by nutritional imbalances. Consulting with a veterinarian to ensure your dog’s diet meets their nutritional requirements is crucial in preventing such deficiencies.

Behavioral Problems

Sometimes, chewing on metal can be a manifestation of underlying behavioral problems. Dogs may resort to destructive chewing as a way to seek attention or cope with anxiety and stress. Identifying the root cause of the behavioral issue is essential to address the chewing behavior effectively. Common behavioral problems associated with chewing on metal include attention-seeking behavior, separation anxiety, and aggression. Implementing behavior modification techniques and seeking professional help when needed can help resolve these issues.

Anxiety and Stress

Anxiety and stress can significantly impact a dog’s behavior, including their chewing habits. Dogs may chew on metal objects as a coping mechanism to alleviate their anxiety or stress. These emotions can be triggered by various factors, such as changes in their environment, loud noises, or lack of mental stimulation. Identifying the source of anxiety or stress and implementing strategies to mitigate these factors can help reduce the likelihood of dogs resorting to metal chewing for relief.

Boredom and Lack of Mental Stimulation

Dogs are highly intelligent and require mental stimulation to stay happy and healthy. Insufficient mental stimulation can result in boredom, which can manifest as destructive chewing behavior. When dogs feel bored or understimulated, they may resort to chewing on metal objects as a form of entertainment. Providing engaging toys, puzzles, and activities that challenge their minds can help prevent boredom and redirect their chewing behaviors to appropriate outlets.

Preventing Inappropriate Chewing

To prevent dogs from chewing on metal, it’s crucial to provide appropriate alternatives and create a safe environment for them. Here are some tips to help discourage inappropriate chewing:

Provide Appropriate Chew Toys

Offering a variety of chew toys specifically designed for dogs can help redirect their chewing behavior away from metal objects. Choose toys made from durable materials like rubber or nylon that are safe for dogs to chew on. Introducing different textures and flavors can also make the toys more enticing.

Supervise and Redirect

Supervision is key, especially during the early stages of training or when introducing new objects to your dog’s environment. If you catch them chewing on metal, swiftly redirect their attention to an appropriate chew toy. Praise and reward them when they chew on the designated toys, reinforcing positive chewing habits.

Training and Positive Reinforcement

Training your dog to understand what is acceptable to chew on and what is not is essential. Use positive reinforcement techniques such as treats, praise, and rewards to encourage them to choose appropriate chew toys. Consistency and patience are key components of successful training.

Create a Safe Environment

Ensure your home environment is free from potential hazards, such as loose metal objects that can be easily accessed by your dog. Store household items, including nails, screws, and small metal objects, securely to prevent accidental ingestion or a potential choking hazard.

Seek Professional Help if Needed

If your dog’s chewing behavior persists despite your best efforts, it may be necessary to consult a veterinarian or a professional dog behaviorist. They can assess your dog’s specific situation, identify any underlying issues, and provide tailored advice and guidance to resolve the problem.

When to Consult a Veterinarian

While occasional chewing on metal objects may not be cause for alarm, there are certain situations where consulting a veterinarian is recommended:

Persistent Chewing Behavior

If your dog persistently chews on metal objects despite your attempts to redirect their chewing behavior, it may be necessary to seek professional advice. A veterinarian can help determine if there are any underlying medical or behavioral issues contributing to the behavior.

Signs of Dental Problems

If your dog exhibits signs of dental issues, such as bad breath, excessive drooling, bleeding gums, or difficulty in chewing, it’s crucial to consult a veterinarian. They can examine your dog’s mouth and provide appropriate treatment if dental problems are identified.

Worsening Behavioral Issues

If your dog’s chewing behavior is accompanied by other concerning behavioral issues or becomes increasingly destructive, it’s important to seek professional help. A dog behaviorist can assess your dog’s behavior holistically and recommend specific strategies and training techniques to address the underlying issues.

Unusual Eating Habits

If you notice your dog exhibiting abnormal eating habits, such as consuming metal objects regularly, it poses a serious health risk. Consuming metal can lead to internal injuries or blockages, which require immediate veterinary attention.

Alleviating Anxiety and Stress

If your dog’s chewing behavior is linked to anxiety or stress, a veterinarian can provide guidance on managing these emotions. They may recommend behavioral modification techniques, environmental changes, or even prescribe medication if necessary.


Understanding why dogs chew on metal is essential for their overall well-being. The reasons can range from natural instincts, exploration, teething, to more complex issues such as dental problems, nutritional deficiencies, behavioral problems, anxiety and stress, as well as boredom and lack of mental stimulation. By providing appropriate chew toys, addressing any underlying issues, and seeking professional help when needed, you can help redirect your dog’s chewing behavior to be safe and appropriate. Remember, patience, consistency, and positive reinforcement are key when working with your furry friend to overcome chewing habits and promote their overall health and happiness.
