Hot spots?
http://www.canismajor.com/dog/hotspots.html
Dusty has a superficial pyoderma, a skin infection known to veterinarians as pyotraumatic dermatitis and to dog owners as 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 the dog 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.
These troublesome sores can seem to arise in a matter of hours with no warning, but they do tend to follow a pattern that helps in predicting their occurrence.
Dogs most susceptible to hot spots are those with heavy coats and histories of allergies, ear infections, flea infestations, irritated anal sacs, and grooming problems such as hair tangles and mats, but any dog can develop this infection. Dogs in warm, humid climates may develop hot spots when they shed their undercoats if the dead hair is trapped next to the skin, and dogs with behavior problems may mutilate themselves by licking and thus encourage an infection to become established.
The most common locations for hot spots are the legs and feet, flanks, and rump — areas that can be reached by licking or biting — but these localized infections can also appear on ears, neck, and chest if the dog is continually scratching.

Treatment
Two approaches are neccessary for dealing with hot spots: treat the sore and remove the underlying cause to prevent recurrences.
Veterinary dermatologist Lowell Ackerman recommends the following treatment in his book Skin and Haircoat Problems in Dogs:
trim the hair around the sore to prevent further spread of the infection and expose the edges of the lesion;
wash the area in a mild water-based astringent or antiseptic;
be prepared to use antibiotics or cortisone if the washing does not give results.
Ackerman recommends against the use of ointments or creams because they can seal in the infection and hinder recovery. In severe cases, a veterinarian may suggest the use of an Elizabethan collar to prevent mutilation and give the spot a chance to heal.
