She is 11 months old and has had several problems from the time she was born.  Given to me at 4 months old.  Crusty ears had test done for mange negative.  Was tested for all kinds of worms etc. negative.  Anal gland no sphincter.  She has diarrhea but not too watery more like pudding.  On her back she had dried crusts and lost lots of hair.  Had a hard time getting it to heal and she still gets crusty near the end of her back before the tail.  Have used several ointments, neosporin having a hard time getting them to soften.  She has no hair on her tail because she multilated herself.  Just recently she has mouth sores on the side of her mouth that get crusty.  I have taken her to 4 vets and one of them being holistic.  They said the tests are alot and they might not get a answer to help her. No operations.  Just trying to make her comfortable.  I have to syringe feed her canned food and dry food from the blender 3x a day or she won't eat.  She is 2.10  All she does is sleep and gets up for short time.  Any suggestions for the crusts, diarrhea (no pumpkin it don't work.  No rice or chicken tried alot of things even a raw and cooked diet.  I need to firm up the stools she may have some kind of bacteria going on because her feces is very stinky.  I have used probiotics.  She also gets fungus around her all of her toenails.  Send your hints and i will try anything to help her.  Maybe you had a similar problem.  She gets wet eyes and they stick together and you can almost peal it off.  Her nose gets crusty from the moisture.  Have tried benedryl.  She has been on clavamox.
