Q. My recently neutered pit bull (5 months old) has a few patches of hair loss, one on the thigh, one on the side rib and one on the lower front leg-

A. My first concern would be that your puppy may have a form of mange called Demodex. It is very common in puppies, usually showing up at 4-8 months of age. It commonly presents as isolated spots of hair loss in which the skin may be a little pink, but the pet is usually not initially itchy. This can usually be easily diagnosed with a simple skin scrape by your veterinarian. It is not a contagious illness, but does require special treatment to clear up the condition. An exam can direct you toward the appropriate treatment......other possibilities would be a fungal or bacterial infection.
