JaCustomer, Are you looking for ways to stop the jumping and aggression?What have you tried so far?Has she been allergy tested ever?What other tests have been performed?
Expert:  Jane Lefler replied 2 years ago.
I was hoping to get some responses from you. Without the answer, it is a bit hard to give you a great answer. However at this age, the first thing I would test would be thyroid function especially since she has skin issues. Often dogs with thyroid problems also have skin problems.
There are other medical issues that can cause aggression as well. Read about them here:
If you want to supply me some of the other answers, I can give you additional responses as well.
