Well I have seen this and this is just me. Now this is just the outside of a dog. The female to me has put the attuide . I guess you would say the Nasty, the mind set in my dogs over the years seems like and the male to me has more to do with the physical side of things, the bone the structure of the dog. Thats a tuff ? man cause all the book heads are gonna come out and say now thats not how it is but I say to them put them damn books down and get you some hands on then tell me .
I will say this I would take a great brood bitch any day over a great stud dog !
Jimmy, to look at your explanation, more in depth. Do you believe that males are typically bred more based off of their physical and performance characteristics vs a female? Thus us as breeders, we may possibily keep a critical eye for those certain traits to appear in pups. The same being said for the females regarding attitude. I could see if a person bred a line of dogs long enough, the cycle would continue with each generation, becoming more uniform until you reach the too tight point. Just some room for thought.
I know for myself, I try my hardest to completely disregard looks when looking at a possible breeding and aim more for performance. Not to say, I dont pay attention to confirmation, just not color, toes, head, etc....lol
