Hot spots are the lay term for moist dermatitis. They are basically self-perpetuating dermatologic issues, usually started as a result of either pain, allergies, or a generalized behavioral issue. Essentially, the dog has some reason to begin licking an area because it makes them feel better. The more they lick, the worse the area becomes. The worse it becomes, the more they lick to make it feel better, so on and so forth. The best way to prevent them is to control the itching while they are healing with anti histamines or steroids, placing an e-collar on your dog, and the use of antibiotics when indicated. In terms of demodectic mange, no this is not usually passed back and forth between dogs. I would suggest that you tell your friend to try and get an ivermectin based product to eliminate the mange. Hope this is helpful for you and Boo. Take care.
