Doggie-Vous Francais?

One day last week, I saw on some news site or other, that there was a proposal to make sure all dogs in Montreal understood cues in both English and French. The notion would be that since in that part of Canada, lots of folks speak French, there shouldn't be linguistic barriers if you were interacting with stranger-dogs and stranger-people. Yearly testing to make sure owners were complying, etc. The thought of legislated language requirements in dog training makes me suffer ennui.

Of course, it was evidently a spoof. But that doesn't stop it from being an interesting thought. Does your dog understand more than one spoken human language? How is your dog doing with just English?
