Seeing either pretty much kills me. Honestly, the latter is slightly better, if only a TINY bit...
I saw a black Lab puppy FLY out of the bed of a pick-up that turned sharply right in front of me, and they ran over their own puppy with a ridiculously huge monster-truck tire. And proceded to stop, then throw the yelping puppy back into the truck bed. =,( I used to cringe every time I saw a loose dog in a pick-up bed, now I have to fight back tears. It's just inconceivable. Anyone who would ever risk their dogs' life in such a careless way doesn't deserve any dogs, ever.
