What Could Be The Reason Why My Dog Is Constantly Scratching And Biting Himself?

It is possible that your dog may be suffering from an allergy or skin irritation, or may just have a case of parasites such as fleas. It is important to take your dog to the veterinarian for an examination to determine the cause. The veterinarian may recommend a medicated shampoo, ointments, or flea treatments to help with your dog’s discomfort. Additionally, it may be useful to provide your dog with environmental enrichment, such as chew toys, in order to distract him or her from the act of scratching and biting.

  • Fleas – Fleas are one of the primary reasons why your dog may be scratching and biting himself. They feed on the blood of your pet and can cause a great deal of irritation. Signs of fleas include excessive scratching and biting, as well as redness and scabbing from the bites. You should consult your veterinarian for proper treatment, which may include flea shampoo, oral medication, or injections.
  • Allergies – Dogs can experience seasonal allergies, just like people can. Pollen, dust, mites, mold, and certain foods are all common allergens in the environment that can cause your dog to scratch and bite himself. In severe cases, your pet may actually show signs of bald patches from acute scratching. Your veterinarian can help you identify the cause of the allergy and recommend treatment.
  • Skin Infections – Bacterial and yeast infections can cause significant itching and discomfort for your pet. These infections can sometimes be the result of allergies, but can also be caused by ear mites, parasites, poor grooming, or poor nutrition. You should consult with your veterinarian to determine the best course of treatment.
  • Ringworm – Ringworm is a fungal infection that causes circular, itchy patches on the skin. It can be caused by many different types of fungi and should be treated with both topical and oral antifungal medications. These infections are highly contagious, so it’s important to prevent spreading them to you and other pets in the home.
  • Hormone Imbalance – A hormonal imbalance can also lead to excessive itching and scratching. Primary causes of this imbalance include hypothyroidism, Cushing’s disease, or improper levels of certain hormones in the body. Your veterinarian may recommend blood tests to determine if your pet has a hormone imbalance.
  • Dry Skin – Dry skin can be an issue for some dogs, especially during winter or other months of low humidity. Symptoms of dry skin include itchy patches, redness, flaky skin, and inflammation of the skin. An omega-3 fatty acid supplement can help provide your dog’s skin with additional moisture while bathing with a mild shampoo can help reduce irritation.
  • Anxiety – Just like in people, anxiety in dogs can manifest as excessive scratching, biting, and licking. If your dog appears to be scratching or biting himself more than usual, it may be a sign of stress. Talk to your veterinarian about a mild behavior modification program to help reduce anxiety in your pet.
  • External Parasites – Along with fleas, other external parasites can cause your pet to scratch and bite himself. Ticks, lice, mites, and various other arthropods can all be the cause of significant discomfort to your pet. Your veterinarian can provide suggestions on how to reduce the number of parasites and treat any skin issues they may have caused.
  • Neurological Disorders – Neurological disorders, such as seizure disorders, can cause your pet to experience movements such as scratching and biting themselves. This is the body’s reaction to an electrical imbalance in the brain. Most seizures can be managed with anti-seizure medication and closer monitoring of the pet’s behavior.
  • Pain – If your dog has any type of injury or health condition, they may be experiencing discomfort and scratching or biting themselves as a means of alleviating that pain. If you suspect your pet is in pain, contact your veterinarian for proper diagnosis and treatment.

Pruritus is the medical term for itchy skin. It occurs in dogs when the skin is irritated or inflamed due to allergies, parasites, fungal infections, skin infections, skin injury, or hormone imbalances. When a dog’s skin becomes irritated, the dog will typically scratch, chew, lick, or rub the affected area until the skin is raw and painful. Symptoms of pruritus include itching, redness, swelling, scabbing, hair loss, or scaly patches. Treatment for pruritus varies depending on the underlying cause. Usually, a combination of prescription medications, shampoos, and other topical treatments are prescribed.

Consulting a veterinarian is the best way to determine the exact cause of your pup’s scratching and biting.

The goal of treating compulsive scratching, licking, and chewing in dogs is to eliminate, or at least reduce the behaviors. Treatment includes:

  2. Behavior Modification: Positive reinforcement techniques can be used to reward the dog when it is exhibiting desired behavior. For example, owners might verbally praise or provide treats when the dog is found not exhibiting the behaviors.
  3. Medication: Veterinarians may prescribe medications to reduce anxiety if the behaviors are highly compulsive.
  4. Activity/Exercise: Increasing activity levels and providing stimulating activities can help reduce boredom and anxiety.
  5. Professional Help: If compulsive scratching, licking, and chewing persists, owners should consider consulting with a veterinary behaviorist.
