Dixie- I've gotta say that was a PHENOMENAL POST.
I think people get so caught up in the idea of having adorable puppies they leave absolutely NO thought to the idea that something might (and most likely WILL) go wrong. Posts like yours are absolutely invaluable because you provide a lone voice of reason, when mostly all people are hearing is "oooh puppies! cute!"
Even the most experienced breeders have stories that will drive you to tears. Just when you think you've got it all figured out, nature throws a curve ball at you. There are things that happen to people that there is NO WAY to prepare for. I know people who have shown and bred dogs for over 30 years, producing multiple champions, knowing their lines backward and forward, doing all the necessary genetic health testing, and yet they'll readily admit to the time they had a litter that a cleft palate puppy was born. Or the litter with the puppy that had it's internal organs developing on the OUTSIDE of its body. Or the litter with the puppy that had a limb that never fully developed.
Pat Trotter (arguably one of the most well-respected breeders of ANY breed in our nation), has some horror stories of ENTIRE litters of puppies being wiped out by a raging parvo epidemic in the late 80s. If you want to talk EXPENSIVE treatment with absolutely NO guarantee that it's going to work, try treating parvo in 8 week old pups.
Point is- SO many things can go wrong, EVEN when the breeding is done under the watchful eye of someone who TRULY knows what they're doing.
Anyone who decides to breed a dog must do so with the full knowledge that they risk the life of their bitch AND the puppies, (not to mention their bank accounts!!!). In other words, you should have a d@mn good reason for wanting to breed, and without a DOUBT if you're new at it, you should have a GOOD mentor who is willing to hold your hand every step of the way.
Thanks once again for a fantastic post Dixie. If that doesn't move people, I don't know what will.
And to the OP- I've got to add to those who have said kudos for asking questions FIRST! With that alone, you've distinguished yourself from the 99.9% of people who come on here that have ALREADY done it, or conversely, are completely set in their ways, and then get angry when we tell them the truth, instead of what they want to hear.
There's a wealth of information to be learned on this site- I highly reccommend reading some of the breeding stickies as well.
And might I suggest that you attend a local dog show just to have a chat with some Boxer breeders? You will learn more in 10 minutes with one of them than any of us can possibly tell you on this board. If you're serious about doing this, and doing it right, THOSE are the people you've got to get in contact with!
