I'd like to explain how we wound up with the prospect of 22 whippet puppies. It's not routine for us -- our puppies are raised inside and underfoot, so that number is a daunting prospect!
A little bit about breeding: You can breed dogs by having one each, male and female. However if you have a breeding program -- a plan, goals, a standard for success, and so on -- you'll probably need six to ten. A small-scale breeder might typically have:
1) Two females that are expected to be bred in the next year or in alternate years. Preferably not at the same time!
2) Two more females that are too young -- we don't breed them before age two because kids having kids is bad for dogs too! These females are generally your own breeding and you want to live with them during their puppyhood and adolescence so you can see who and what they really are. Temperament? Health? Structure? Behavior around other dogs? Around younger puppies? Around people? Even when another breeder (selling you a dog) is absolutely honest, you cannot get equally detailed information. Mom is considered to be 60-75% of what you get
