Hot Spots

Hot spots are surface skin infections caused when populations of normal skin bacteria grow and overwhelm normal resistance. They are generally circular patches that lose hair, can be swollen, may exude a smelly pus, and can be painfully itchy, causing your pet to scratch, lick, or bite to the point of self-mutilation. Untreated hot spots can spread and provoke a normally even-tempered dog to growl or nip when touched.
