Are you looking for something to give as a 'snack' or are you looking to get something that she can have to get her "chew on'

I really like the "Kong" bone. They come in different colors and have holes in each end so that you can put something it them like peanut butter or cheese.
I have used them for about 4 years and my Rotties love it. I have been using the same 6 bones all that time and never had to replace them. And believe me, my boys can bite/chew through ANYTHING
They love to just sit and gnaw on them for hours.
