I'm sorry you haven't gotten any replies to your post yet. Sometimes I think people don't check in on dog behavior threads enough.

I've had dogs who were not interested in toys either, but they had other attributes that made them enjoyable to interact with. Perhaps she would be interested in obedience training or agility. Having you tried throwing a ball carefully to see if she would catch it? Some dogs you have to almost play with them with the toys. Tucker loves it when I make the toys *come alive*. Hannah enjoys *find the kong*. I will hide it in one room while she is on a sit/stay in another room and then when I say okay, she comes running in and starts looking for it.

When your dog doesn't adapt to what you want to do, see if you can find out what they enjoy and go from there. If nothing else, a nice walk is always enjoyable.
