The word manipulation has a [DD] connotation in this passage.
After many decades of human manipulation,
English bulldogs are so far from their natural
ancestors that they commonly suffer from
abnormalities, such as small windpipes and
closed nostrils. Our efforts to breed so many
of these dogs have diluted the bloodline,
thinning and weakening it further with every
generation. Rather than creating a
sustainable breed of dog, we have opted for
an unsupportable dog breed that cannot be
maintained for much longer.
