how much is that doggie in the window

i'm not much of an animal lover, but i observed two sad dog-related scenarios yesterday.

1) a dog was tied up outside of a restaurant. this dog appeared to be shivering pretty badly and it was crouched up into a ball, presumably trying to keep itself warm. the sight sort of haunted me afterwards. my friend tried to convince me that dogs don't really get that cold, but this dog looked pretty freaking cold to me.

2) a man was walking his 3-legged dog down the street. the poor dog was hobbling along!
