If your dog is constantly scratching and biting himself, it could be due to a variety of possible skin or environmental issues. These can include mites, bacterial or fungal infections, allergies, anxiety or stress, or even fleas. It’s important to identify the underlying cause of the problem before you can determine the best course of action for your dog, so a trip to the vet is often the best solution. The vet can run tests and look for any signs of inflammation or infection that suggest a particular problem. In some cases, simply changing the diet or medication may help, but in others, additional measures may be needed such as antifungal or anti-allergenic medications, or further investigation into any underlying allergies or environmental factors.

My Dog Is Constantly Scratching And Biting Himself: What Could Be Wrong?

There are several possibilities, including:

Skin Allergies: Skin allergies in dogs can be caused by environmental factors such as dust and pollen, food allergies, parasites, contact allergens, or environmental allergens such as fleas. Allergens can cause the skin to become inflamed and irritated, resulting in the dog chewing, licking, or scratching itself in an attempt to relieve the discomfort. Allergens can also cause hair loss, redness or swelling, and lesions on the skin. Depending on the type and severity of the allergy, a range of medications and treatments can be used to relieve the symptoms and improve your dog’s quality of life.
Fleas: Fleas are tiny parasites that can live in the fur of your pet or in your carpet, bedding, or other fabric items. Fleas feed on your pet’s blood and can cause intense itching and discomfort. As your pet tries to scratch and bite at the itch caused by the fleas, this can lead to lesions, hair loss, and skin infections. Flea saliva is also an allergen and can cause an allergic reaction in pets, leading to further scratching and biting.
Infection: Infection can cause your dog to constantly scratch and bite himself due to itchiness and irritation of the skin. The itching is caused by an inflammatory response to the infection, which can be caused by bacteria, viruses, parasites, or a combination of the three. Bacterial and viral infections lead to the release of toxins that inflame the skin and cause an allergic reaction. Parasite infestations can cause both itching and skin damage. In addition to these conditions, some dogs can develop an allergy to a particular food, environmental irritants, or topical treatments. All of these conditions can lead to intense itching and skin irritation, causing your dog to scratch and bite himself frequently.
Dry Skin: Dry skin can cause a dog to constantly scratch and bite itself due to itching and irritation. This is caused by various skin conditions, allergens, or parasites that can cause skin dryness and inflammation. Additionally, dry skin can be the result of an underlying medical condition, such as hypothyroidism, digestive problems, or environmental factors, such as harsh weather or exposure to certain chemicals. Lastly, if the skin has insufficient moisture, dry skin can worsen and cause the dog to scratch even more. In order to help soothe the skin and reduce irritation, it may be helpful to apply topical lotions or sprays to the affected areas. Additionally, since the underlying cause of dry skin needs to be identified, it is important to contact your veterinarian for further advice.
Anxiety: Anxiety can cause dogs to excessively lick, bite, and scratch themselves. This behavior is known as psychogenic alopecia or fur-plucking. Dogs may engage in this behavior because of boredom, chronic pain or discomfort, or the feeling of being overwhelmed. Anxiety can lead to compulsive scratching, biting, and licking out of a sense of fear or unease. This behavior is often accompanied by other signs of anxiety, such as panting, trembling, vocalizing, sleep disturbances, and overall restlessness. Environmental factors, such as a new home, changes in routine, or uncertain situations may trigger the start of or worsen this behavior.
Mange: Mange is caused by a mite that burrows underneath the surface of the skin. The mites cause intense itching, leading the dog to scratch and bite themselves in an effort to relieve the itchiness. The scratching and biting can cause red, inflamed skin and hair loss, as well as open sores that can become infected. If left untreated, the condition can cause serious damage to the skin and lead to secondary bacterial, fungal, or viral infections.
Parasites: Parasites, such as fleas, ticks, and mites, can attach to a dog’s fur and skin, causing an allergic reaction resulting in excessive itching and biting. These parasites, which can include anything from microscopic mites to large fleas, feed on a dog’s skin, coat, blood, and other bodily fluids. As they feed, they cause irritation which leads to the dog scratching and biting itself in an attempt to alleviate the irritation. Flea bites can cause severe irritation and discomfort, and can even lead to skin infections. If left untreated, the parasite infestation can worsen and cause long-term damage to the dog’s health.
Ear Infections: Ear infections can cause excessive itching and scratching as the infection causes pain and irritation. Bacteria and yeast can inhabit the ear causing inflammation, which can lead to severe discomfort and itchiness. The itching can be so unbearable that a dog will attempt to alleviate the problem by scratching and biting himself.

Pruritus in Dogs

Pruritus is the medical term for itching. In dogs, pruritus is a common symptom of allergies, parasites, skin infections, or hormonal imbalances. Itching can also be caused by stress or other environmental triggers. Signs of pruritus include excessive scratching, licking, rubbing, or chewing scabbing sores, and red, flaky, irritated skin. Treatment for pruritus in dogs will depend on the underlying cause and may include topical medications, antihistamines, immunosuppressants, and removal or avoidance of allergens.

If your dog is scratching and biting himself but no fleas are present, he may be suffering from allergies.

How To Treat A Dog Who Is Constantly Biting And Scratching

Temporarily Confine the Dog: If you know your pet is likely to bite or scratch, confining them to a safe room with their bed and access to food and water can help limit their access to people or other animals. If it is a puppy, then a crate can help them feel secure and also keep them out of trouble.
Distract and Redirect the Behavior: When your pet starts to bite or scratch, try to distract them with a toy or even a treat. This will help them focus on something positive rather than hanging on to whatever they are doing.
