She is still a youngster, I bet she will end up being one of the best dogs you have ever had. To be able to run her with a bike leash, she has to be well behaved. A 40 lb dog could pull you off balance easily. I am sure you will give her plenty of time to mature.
My own dogs are not perfect but we get along well.

I sure hope so. Too late to get rid of her now. lol
Thanks!
