Dog Allergies & Itching

Allergies and itching can make a dog miserable. It also can lead to more serious health problems, such as infections. There are effective treatments available once the cause of the problem is determined. With some diligent care, your dog will be back to his healthy, non-itchy self in no time.

  1. Causes

    • Dog allergies have many possible causes. Food sensitivity is a frequent cause, and ingredients found in dog food are often the culprits. Grains, milk products, corn, dyes and preservatives are known allergens.

      Environmental factors, such as mold, pollen and dust, can be a problem. Fleas are a well-known cause of allergies and itching in dogs. Contact allergies can be caused by detergents used to wash bedding.

    Symptoms

    • Itching is a problem, as well as a symptom. Additional symptoms of allergies include rashes, reddened skin, red and swollen eyes, hair loss, congestion, sneezing and runny nose. Food allergies also can cause gastric upset, vomiting, diarrhea and lethargy.

      Itching often will cause your dog to lick and bite at his feet or rub his face against the floor. Sometimes you will notice him scooting across the floor in an attempt to alleviate the itching.

    Treatments

    • Treatments for allergies and itching depend upon the cause. Food allergies are usually effectively treated by simply switching to a dog food containing no allergy-causing ingredients. Environmental allergies are helped by keeping the dog inside as much as possible and clearing your home of any mold and dust. Eliminate fleas by bathing your dog with flea shampoo and treating your home. Use detergents that are fragrance-free, with no dyes.

    Medications

    • Antihistamines, sold over-the-counter, can alleviate the itching and symptoms of allergies. Your veterinarian can prescribe steroids, either oral or in ointment form that is applied topically.

      Flea medications are available from your veterinarian. These medications will kill the fleas as well as prevent reinfestation. Dogs living in warmer climates will need to be on a flea treatment program year-round.

    Complications

    • Allergies and itching left untreated can lead to further complications. Your dog's immune system may be compromised, providing an environment for disease. Secondary infections can occur as the result of scratching, which opens the skin, allowing bacteria to enter and grow. Hair loss, as the result of constant scratching, can become permanent.
