First of all, I am not a professional animal person, Ha, I'm a nurse and have animals and do alot of research on them so I will tell what I know about hair loss. There are alot of reasons that dogs lose their hair. I'm assuming that there isn't any skin reddness or irritation on these areas? If so, this could be something else, a yeast/bacterial infection, a ringworm,mange or an allergic reaction that has caused intense biting or chewing. If there isn't any obvious skin problems, I would look into either a diet problem or a stress induced problem and with the history given, the later sounds to be more likely. Be sure that the current diet is a balanced diet with the proper % of minerals, enzymes, vitamens and protein. Science diet, Eukanuba and Iams are all well balanced foods.The stress should resolve itself with a new and loving home with you, bless you for taking him in! Linatone, is a great product available at PetSmart that is a oral solution for Skin and Coats. Nutrivite is a good line of vitamens and supplements.I hope you get this problem resolved!
