The term used for bald spots. Most common is the bare spot on the ridge of the nose - more common in summer months and caused by fly irritation and rubbing. Some owners have found improvement by applying Vitamin E Oil, Vaseline, or Preparation H to the area. It normally grows back in winter months. If the area with hair loss is crusty, flaky, thickened or reddened, ringworm, mange, a type of fungus, or zinc responsive skin disease may be suspected. When fleece is coming out or breaking off but not leaving a bald spot, it may be due to shedding or fiber break. (see specifics under ringworm, mange, fungus, bare nose, elephant skin, or hair loss)
