I've always regarded people who speak to animals as if they're humans as particularly idiotic. And those who speak to them as if they're cute little babies are even worse.
My wife is away for a week, so all the dog-walking and feeding duties have fallen on me.
When trying to get Tyke to come inside, or get him away from some particularly alluring smell by the roadside, I've found myself talking to him -- in English, which he doesn't understand -- using an emphatically expressive tone of voice. Somehow it just seems like the most natural thing to do.
I don't talk to him as if he's a cute little baby, though, but more as if he's a recalcitrant three-year-old.
Gotta draw the line somewhere.
