I have a border collie/australian shepard. She is 9 years old and is very healthy and happy. Lately I have noticed that her fur has been dull and feels dry to the touch. She has had hot spots on her back, but have cleared up thanks to a topical natural ingedient foam that I applied. Now that the hot spots have cleared up, I have noticed substantial hair loss on her hind legs and tail. She is still itchy, but no new hot spots have appeared. I have her on Revolution, so fleas shouldn't be a problem. She is not losing hair in spots, it is all-over thinning and it is quite noticeable. I am a college student and have limited funds, so I am hoping that this problem isn't too serious. Are you familiar with this problem? Is there a vitamin deficiency (if so, which one?), or is it more serious?
