That dog!

Ok, I don't remember what they called their little fiery fur ball of a dog, but I do remember he became a member of their family. Every time we visited he would come flying up to the window and greet us with a barrage of barks and jumps. Did I say jumps? Yes, this dog could jump. He would go flying from the floor to the couch with precarious speed. What was his/her name again? Naturally, he had to be on the water!
