Why Does My Dog Chew On Himself


Dogs are known for their quirky behaviors, but one that can be concerning for pet owners is when their furry friend starts chewing on themselves. This behavior, known as self-mutilation or self-chewing, can be a sign of underlying health issues or behavioral problems. If you’ve ever caught your dog gnawing on their own skin or fur, you may be wondering why they do it and what you can do to help them stop. In this article, we’ll explore the reasons why dogs chew on themselves, as well as common concerns and answers related to this behavior.

1. Anxiety and stress: Just like humans, dogs can experience anxiety and stress, which can manifest in various ways, including chewing on themselves. According to a professional in the field, “Dogs may chew on themselves as a coping mechanism for dealing with stress or anxiety. It’s important to identify the underlying cause of their anxiety and address it to help them stop this behavior.”

2. Allergies: Dogs can develop allergies to various environmental factors, such as pollen, dust, or certain foods. These allergies can cause itching and discomfort, leading to excessive chewing and licking of their skin. A veterinary dermatologist explains, “Allergies can trigger intense itching in dogs, prompting them to chew on themselves in an attempt to relieve the discomfort. Identifying and treating the underlying allergy is essential to stopping this behavior.”

3. Parasites: External parasites, such as fleas or mites, can infest a dog’s skin and cause intense itching, leading to self-chewing. A veterinary parasitologist states, “Parasites can be a common cause of self-mutilation in dogs. Regular parasite prevention and prompt treatment of infestations are crucial in preventing this behavior.”

4. Skin infections: Dogs can develop bacterial or fungal skin infections, which can cause itching and discomfort. A veterinary dermatologist warns, “Skin infections can lead to intense itching and irritation, prompting dogs to chew on themselves. It’s important to consult with a veterinarian for proper diagnosis and treatment of skin infections.”

5. Boredom: Dogs that are bored or under-stimulated may resort to self-chewing as a way to alleviate their boredom. A professional dog trainer suggests, “Ensuring that your dog gets enough mental and physical exercise can help prevent boredom-related behaviors, such as self-chewing. Providing interactive toys and engaging activities can keep your dog entertained and prevent unwanted behaviors.”

6. Dental issues: Dental problems, such as tooth decay or gum disease, can cause pain and discomfort, leading to self-chewing. A veterinary dentist explains, “Dental issues can be a hidden cause of self-mutilation in dogs. Regular dental check-ups and proper oral hygiene are essential in maintaining your dog’s dental health and preventing this behavior.”

7. Compulsive behavior: Some dogs may develop compulsive behaviors, such as excessive grooming or self-chewing, as a result of genetics or past trauma. A professional animal behaviorist states, “Compulsive behaviors can be challenging to address, as they often stem from underlying psychological issues. Working with a certified animal behaviorist can help identify the triggers and develop a treatment plan for compulsive behaviors.”
