I agree with you whole heartedly Jack. I wish I had known these things years ago. I haven't bred any dogs in around 6 years. That's actually real good. I was simply copying proven formulas and trying to repeat things already done. Now that I have a much better understanding of creating dogs and have the best I've fed left, although old, that's exactly what I intend to do. The litter that produced AC/DC's Diablo is the litter I am hanging my hat on. I guess in around 18-24 months, we'll know exactly how that pans out.
