Thanks everyone 
She is a lovely dog,perfect match for Bailey and us.She is still very submissive but becomes a different dog when She greets me in the morning and when she knows we are going for a walk.She wont go out the back in the morning for anyone but me and just watches and follows me everywhere,she couldnt care less about anyone else. 
She has put on weight and is now looking a bit chubby 
Her hair is growing back on her tail and she had a sore on her nose for weeks which was not healing,but now thanks to some honey it seems to be healing now.
