The Daily Puppy states that dogs get a canine eczema also called pyotraumatic dermatitis, acute moist dermatitis, wet eczema and hot spot. Canine eczema occurs when a skin irritation makes a dog lick and bite the area, causing a lesion.
According to The Daily Puppy, dogs with more hair are susceptible to canine eczema due to dense hair on the body blocking airflow. Regular haircuts, brushing and bathing during warmer weather prevent hot spots. Veterinarians treat canine eczema with topical and oral antibiotics along with shaving the hair around a lesion. An Elizabethan collar is sometimes applied to dogs suffering with eczema to prevent them from further infecting the lesion with more chewing and licking.
