I LOVE that name and Rook was at the top of my list to go with Kastle but I know someone locally that trials in agility that has a dog named very similar. And I happen to not care for the owner in particular so that really...tainted it. Your registered name rocks. So, I've changed his name already. My flyball friend came up with a name I absolutely adore and knew right away was the right one - Limit!! Is that not the coolest name? And totally unique - I don't know any dogs named Limit! So...registered name ideas...Brokenstirrups No Limits? Brokenstirrups Take it to the Limit?
