Wow, those were pretty awful.  I also cannot imagine getting a pet just to stay outside all day....waiting for his people to come show him a few minutes of affection!  Even my best friend's HUGE Great Dane lives inside.     
I do feel bad that they will never know the unconditional love of a dog though.  I can't imagine not wanting to completely spoil my Levi after he gives me one of those looks of complete devotion and trust.  Sweetest thing ever.
