And i disagree with the both of you. Dogs of sound mind and health should be bred. Not JUST purebreds. Purebreds are actually a VERY recent trend in the history of the domesticated dog. No different than the trend of the designer dogs (other than that the Purebred world has evolved a bit to be more responsible.)

I do agree though that NO dog should be bred as a means of profit. (And unless you are asking large sums a properly cared for pack will usually leave you in the red... speaking of their costs vs. the price you are asking.)
