On the original post most not all breed because of the blood,some breed for marking and other breeding are done just because they have a male and female! dig deeper into any line off hounds that your interested in! Also try to reframe from asking questions that May have you looked at as a green horn! Nothing wrong with it in my eyes I have had dog all of 30 plus years and I'm always learning something new! bottom line is your the owner are the deciding factor of what a stud dog is!
