She looks like the sweetest dog, precious. Please don't ever give up on her, although it sounds as though you love her dearly. Anyway, have you tried buying various styles of toys- soft stuffed animals, my dogs favs. You could also try a Kong sold at Petsmart and Petco. In case you aren't familiar, its a plastic toy filled with treats or peanut butter-like Kong filler. Most dogs love to try to get the treat out or filler out of the Kong and can play with it for hours.
