Thankful Day #25

Thankful Day #25: I am thankful for dogs. Obviously, I'm biased. Nevertheless, fascinating research suggests that dogs evolved from less-human-avoidant wolves, probably used by early humans for assistance in hunting given their superior sense of smell. Dogs read human faces like humans do. They can understand symbolic gestures like pointing (chimps can't). And, of course, they're our best friends.
