Well...first, if the Breeder has her name on the papers...and it will already be imprinted, you'll have to fit that in there. I think you have some 35 letters. Secondly, you won't be able to use the - in the name. You can skip spaces tho.
Maybe you can incorporate a hobby of yours, or books, or characters, or do something with his black coloring. Our AKC and CFA names always have something do to with cars, since my husband is a huge car nut. He gets a car, I get an animal!
I think there is a thread running in the "Pets" section on how you named your pet. You may get some ideas there. Good luck and keep us posted! OH...and pics of Bruno would be great!
