Cats are OK, but...

Which would be the conservative dogs, and which would be the liberal? Here's a hint: the conservative dog did something besides barking for help. Also, conservative dogs aren't content to make noise until somebody else saves them.

Last hint: how many times do you have to tell liberals not to stand up in a canoe?

I have to admit that a small voice is telling me that this could have been staged. Could have been.
