How does breeding early give more female pups?

Male sperm are faster, but die sooner. Female sperm swim slower, but live longer. So if you breed early (eg before the eggs are ready) the majority of the male sperm will have died before there were eggs to fertilize, but the female sperm will still be there. If you breed late (eg after the eggs are ready) the male sperm will get there and fertilize all the eggs before the slower female sperm arrive.

Breeding true to type – Breeding true to the breed

Those who argue against linebreeding are inevitably those who have never successfully bred animals themselves - most often they are college professors. The same people who have bred nothing more complicated than fruit flies or no more demanding than lab rats are often the most vocal about how others should breed performance animals. These "know-nothings" advocate the notion that out-crossing is in and of itself good because it produces some thing they often refer to as "hybrid vigor".

How Often Should You Breed Your Bitch?

It's interesting to hear many other people's opinion on how often to breed a bitch. The general consensus now is that a bitch should be bred back to back (from one heat to the next) and then skip a heat, be bred again back to back. The bitch should never be bred on her first heat, and I've found it safer to start on the 3rd heat. The bitch is much better prepared mentally and physically to care for her pups.
