When I first got started this was the advice I was given...use a larger female for larger litters & easier whelping, with a smaller stud to give smaller puppies. When I got serious about improving the breed, and specifically my program, everything about my initial understanding went out the window. Now I wouldn't hesitate to use a male that is bigger than my female if I know enough about the lines and he has the specific qualities I am looking for.
To take a shot at the original question, I think peer pressure is why the larger males aren't popular. Smaller males are what "everyone is using" and since most don't study enough to know it might not be best...they just do what everyone else is doing. I also think this is why we see so many poorly proportioned puppies. Small males and large females often don't throw a well proportioned puppy. In my experience it often produces a longer body with shorter legs, and a smaller head with large ears. These two proportion problems are very common in the breed nowadays. |
