Just because I'm apparently famous for sarcasm, I'll respond to you straight. If by "talk" you mean using sound to communicate, why are you discounting growls, whimpers, howls, and whines?
If by "talk" you mean communicate, then dogs have a much richer vocabulary than humans. They use posture, smell, smelling, sound, touch, and the big giveaway: the tail.
I don't speak Chinese, so there are humans I cannot communicate with. I do, however, speak Doberman, so there are dogs I can. We both have something to learn.
