My dog understands everything I say. Sometimes she'll come sit by me while we're watching TV and and I'll say something to the effect of: "Jesus Christ, Oreo, You stink!" and she'll get all embarrassed and go sit about 5 feet away from me - look back to see if I can still smell her - then possible go upstairs if it's still too stinky. It's also the only way I can convince her to take a bath... Telling her she stinks. She won't follow me up to the tub unless I tell her how I can smell her ass from 5 feet away. We have other conversations not related to her smell, but that's all I can think of at the moment. I talk to her all the time though.
