You can stuff a treat inside of the toy (if the toy is made for that), but make sure she is able to get the treat out. If your toy isn't a treat stuffer, you can rub a treat on it. The smell of the treat should peak her attention enough to introduce play.
Other things to consider:
- The toy may be too large for her/too hard to chew
- Have you tried a variety of toys (plush/rubber/rope toys/squeakers)
- Place a toy under your bed covers for a week (to help hold your smell) and then give it to her
You may have tried some or all of these things. I am just offering my thoughts.
