Alice, this is from the AKC breed standards (my bold)....

Color
The colors are fawn and brindle. Fawn shades vary from light tan to mahogany. The brindle ranges from sparse but clearly defined black stripes on a fawn background to such a heavy concentration of black striping that the essential fawn background color barely, although clearly, shows through (which may create the appearance of reverse brindling). White markings, if present, should be of such distribution as to enhance the dog's appearance, but may not exceed one-third of the entire coat. They are not desirable on the flanks or on the back of the torso proper. On the face, white may replace part of the otherwise essential black mask, and may extend in an upward path between the eyes, but it must not be excessive, so as to detract from true Boxer expression. The absence of white markings, the so-called "plain" fawn or brindle, is perfectly acceptable, and should not be penalized in any consideration of color. Disqualifications Boxers that are any color other than fawn or brindle. Boxers with a total of white markings exceeding one-third of the entire coat.

So sadly, whether it's moral or not, some breeders apparently can't be bothered with pups that are too white. Instead of doing the right thing and letting an otherwise perfectly healthy pup nurse frpm it's mother, then selling it or adopting it out as a pet only pup with a must spay/neuter clause - they are discarded. Sad isn't it.
