Our Australian Shepard mix is pulling her fur out, isn't gaining weight and suddenly started going to the bathroom in the house. When we got her she asked to go out but now she won't even bother.
She itches all the time, but her skin doesn't look red or scaly. Like hot spots. Can any one give me any ideas as to what might be wrong?

I'm at a loss, we've tried diffrent shampoos, and hydrocortisone.
