My dog is called Chelsea. I got her from a shelter, and when they gave me her paperwork, she had already had 3 or 4 owners and each one gave her a different name, so I kept the last one to avoid confusing her even more!
When I was very young, I had 2 rabbits one called Andy Pandy and the other called Looby Loo after the children's TV
I also had a gerbil, which I called Jeremy. Not sure why!
Our family dog when I was young was called Rusty, because of his color.
Currently we also have my brother-in-law's pit bull Jake living with us. Not sure why my brother in law called him that. I find it easier to call him Dick, because he is so stupid!
