Sam...
Pixie will never be gone...she will always be here. Watching over Tucker, your family, and you. Especially you.
There is only one Pixie...nothing can change that. But there is also one Tucker, and one of every dog in your life. No one dog is the same. Tucker, like Pixie, holds a neverending love for you, his one true master. Not only are we here for you, but he is too. Never forget that.
I'm sorry.
