Also called moist eczema, hot spots are the sudden appearance of wet, circular patches of infection on the skin that create intense itching and irritation. Hot spots are the result of a tick or insect bite, or even from a mild abrasion or moisture contacting the skin. They can spread very rapidly across the skin surface and beneath the fur, so they may be difficult to see. It is best to trim the fur around the affected area to allow air to assist in drying.

Daily cleaning of the hot spot with sterile saline, NOT hydrogen peroxide, every two hours for the first day or two will speed up the healing. Also, any topical antibacterial ointment with arrest growth of the bacteria. Sometimes oral antibiotics and steroids are necessary to help these areas to heal. These skin lesions can take a week to finally dry and look like they are going to heal. The fur begins to grow back, sometimes a different color, within two weeks.
