Ave made me mind up regardless what some people think about Collie crosses as a think the breeding of a first x collie to a first cross beddy will throw some good pups and am using gvc dog to be the sire over me bitch.Sound mate ,as long as you are happy,that's all that matters ,just think it get ridiculous folk getting personal of the question you asked
Good luck with the breeding,and hope you get what you want,........
Have you thought about using a bull cross?
