Common Causes of Dog Skin Conditions

Rashes, dry skin, allergic reactions to flea bites, and itchy skin are some of the most common skin problems veterinary dermatologists deal with on a typical day.

  • Allergies. Allergies are a leading cause of dog skin problems. They can be caused by a variety of allergens that attack the immune system, including food, environment, and fleas. Allergies can cause itching, redness, swelling, and hair loss.
  • Hot spots. Hot spots are small, moist, inflamed areas of skin that are often caused by excessive scratching or licking. They can be very painful and can lead to infection.
  • Dermatophytosis (ringworm). Dermatophytosis is a fungal infection that can cause hair loss, scaling, and crusting of the skin. It is contagious to both dogs and humans.
  • Mange. Mange is a parasitic skin infection that is caused by mite infestations. There are three types of mange in dogs: sarcoptic mange, demodectic mange, and otodectic mange. Sarcoptic mange is the most common type and causes intense itching. Demodectic mange is a less common type that is caused by mites that live in the hair follicles. Otodectic mange is a type of mange that affects the ears.
  • Bacterial infections. Bacterial skin infections can cause a variety of skin problems in dogs, including folliculitis, hot spots, lesions, ear infections, and pyoderma.
  • Viral infections. Viral infections can also cause skin problems in dogs, such as canine distemper and canine papilloma virus.
