I LOVE the name Kipper - if you have kids, you may have seen the British cartoon "Kipper the Dog". Kipper is the COOLEST dog and I used to love to watch that cartoon with my granddaughter. When we got Rexy, I wanted to name him Kipper, but everyone else wanted an "R" name to go with Rowdy. I love Rexy and I'm happy with that name, but every once in a while I wonder that maybe I should have held out for Kipper.........
Good luck with your choice - I know it is hard.
By the way, he looks like a Kipper in your avatar!
