Hi, I have been reading over your posts on choosing a name and want you to know you are not alone. I always have such a hard time picking the right name.
I think Sophie is very cute, but the only way to see if you are really comfortable with a name in my opinion is to say it out loud. Act like you are calling her...

. Names can look very cute written down, but how do they feel saying them out loud.
My boxer is famale and her name is Sidda, Sidda Lee actually. It was a character is a movie full of southern people and I thought my little Sidda looked like a droopy eyed, porch lazing hound...

. I have yet to come across another Sidda!
I like the names Irelyn, Sloane, Paris and Jaida as possible ideas for future female boxers. Hoss is kinda cute too and a play on how tough boxers ladies can appear.
Good luck!
Amy and Sidda
