sorry you were offended, but reasonable questions I thought to a question from someone who is hoping to have a litter of puppies. You really should think long and hard about what you are about to undertake, and why you want a litter from your bitch in the first place.......and take the time and trouble to read the links Lankeela has posted. I have two bitches, one from whom I would love a litter from, she is a good specimen of the breed and I know of a lovely stud that is compatible with her line, and apart from wanting to keep a puppy myself, her breeder and a friend would want one......but.......having seen my friend lose three puppies within two days of birth, the mother was quite poorly, her milk dried up, - she had to hand rear the remaining puppy, had no sleep for almost 4 weeks other than the odd hour here and there, numerous trips to the vets with both mother and puppy, I am not sure I am able to commit to that physically or mentally, are you? Being a dog lover is not enough reason to undertake this kind of commitment lightly - and as this is your first time, which I assume it is, it would be a good idea to have someone with experience close at hand.
