• " Oh and the structure of the Boxer, with it's exagggeratedly deep and narrow chest...Well the resultant diminished lung capacity that comes with that form was also reproduced in these dogs. As was its weak heart." then what is this guy talking about? when I see boxers in person their build looks like they are very agile etc. not so short and wide like my dogs. im sure everyone has seen this as well http://www.youtube.com/watch?v=9eg2wGKzdc8
