Well if that is your choice then you are entitled to do so but please don't come back and say your female bit your baby because it hurt one of her puppies and she felt protective. Please don't come back and say help the puppies are dying and they don't seem to eat. Please don't come back and say that someone took one of your puppies and then you found out it was left outside and has heartworm and ended up at the shelter or dead. Please don't come back and say that your female and all of her puppies died because one got stuck and you didn't know what to do. PLease don't come back and ask for help if you female gets mastitis and her nipples burst from infection and now you have to hand raise the babies.
There is a lot more to having litters of puppies than letting two dogs breed and if you don't feel that way then that is your perogative but you cannot expect others to share your view. You will do as you please since they are your dogs and it is your child but you are going about things all the wrong way wihtout enough knowledge of the things that can go wrong and what to do about it. Yes they are dogs but that does not give us the right to breed them indiscriminantly and to endagner their lives for our own gain without taking the necessary steps, both monetarily and educationally to ensure the best possible outcome for the animals involved. Yes bad things happen to good breeders and nothing happens to some bad breeders but that doen't mean it can't and won't.
If you truly want to breed boxers then please get together with an experienced breeder to find out everything you need to know. A book or two aren't going to give you the experience of someone who has done it for many years. PLease findout about the helth testing and all of the things that can go wrong so if it happens you are prepared. PLease have your dogs checked over for genetic health problems with X-rays and holter monitors to make sure their hearts are sound. Even if you don't want to show the dogs they deserve the best posisble chance for a healthy life, not just to be born because someone wanted to calm their mother down.
I wish your dogs good luck.
