My dog has spots on the middle to the back of her body where she lost hair and is kind of crusty. There's also a part of her behind that looks like a open sore. I'm not to sure what it is. Help?

This looks like a bacterial skin infection. You can bathe her with a medicated shampoo once or twice weekly and brush her daily to remove the crusts and loose hair. I recommend adding a fatty acid skin supplement to her diet. If the sores are open and raw looking use a topical antibacterial ointment on them. If they are not improving with your home care then I recommend a veterinary exam for a diagnosis. They most likely will prescribe several weeks of antibiotics. Also make sure there are no fleas contributing to the itching and sores., using an oral flea prevention is best as bathing regularly will wash off a topical flea prevention.
