Just a little detour...I found this gem from News from Aspen Meadows, about her elder dog and triumph over squirrels.
Let me say I'm a vegetarian, and I adore animals and love the squirrels in our neighborhood. I HATED it when Mojo and Lebowski would occasionally be victorious in their quest to rid the parks we frequented from rabbits, groundhogs, and yes, squirrels. I love what she wrote, though, and when I read it I had tears in my eyes, remembering my old girl, who was a hell of a hunter almost to the end. I wanted to share it with other dog lovers who can relate.
