Aside from the "designer dog" issue and regarding the ad referred to in the first post, any respectable dog breeder would only breed dogs that were fine examples of the breed after determining that the dog conformed to breed standards and had excellent health. The dog should also possess a good pedigree (though I will admit to occasionally seeing nice dogs that were bred without papers but I wouldn't endorse doing that). This ad to buy any old dog for breeding purposes is obviously from a disgusting puppy mill that would breed without regard to passing on genetic problems to make the almighty dollar.
