just to give her a boost for success my friend has a now 11year old collie/gsd cross who was a rescue. He came with many problems and because of that whenever people came round he was kept in another room.
It has taken me many months of meeting him using the techniqnes of not ignoring him, just sitting in the same room as him dropping treats when I am in the room with him, eventually he has been prepared to take a treat that just happened to be in my open hand as he gingerly sniffed me and to a dog that now runs up to say hello to me asks me to tickle him and I can now look after him if the owners go out.
A long job but such satisfaction when it works. I did all this at his pace and btw I am not a trainer , behaviouist or anything just using common sense and the wonderful things I have learned here
good luck
