Why Boxer dog's die young

Hey Mike I'll pitch in my .02 now.

From experience with my German Shepard I know that pork and chicken BONES are a no no. They shatter when the dog bites them and can get lodged in the throat.

As for grapes,well maybe the same reason you dont give whole grapes to a baby? Choking hazard once again,just the right size to get stuck in th throat if it's not chewed.

There are many dog foods which contain rice,not wheat.I found my shep liked the rice food better anyways.
