Wow this thread just keeps on going! I have read it all and to me the dog is the same.Just one is all prettied up and the other looks a little unkemp.I would LOVE to take her in my home if I could but I don't have that kind of money to throw around.In that why don't you put her in Puppy school,I put all my dogs in it no matter what there age.It cost just $75 here to go.I have never given up on any of my pets.All my dogs have a history of some kind.Jasper our Yorkie is our first dog we ever owned the actually has no problems.All our others were rescues and were abused in some way,but they are still with us and we are getting ready to put Tink in a class in May because she doesn't like people.She is great with dogs and hids from all of us.Not giving up on her I am putting her in school and just give her unconditional love.As I always say I will love it out of them
Good luck! I hope this is just stress for her and she senses something is wrong and is acting out on it and she gets better.If not send her my way I will work with her and put her in class and then give her back when it is all done.
