Cookie is the little one. The other 2 are my sister's Tosa Inus, Coach and Bella.
It's a hoot watching the 3 of them play together. Don't worry, it's always closely supervised. Thankfully, Cookie can run really fast and she stands under Coach a lot of the time so he can't "get" her. :)
I have to say you would be surprised how much your household would miss her energie if she were not there after making her presence known. When Lilly went in for surgery I could not believe how deadly silent it was without her. I missed her and we still had two other dogs at home too. LOL Enjoy that little cutie pie.
