Some people are using buttons to get the dog to reply in a context format rather than just gauging enthusiasm for a given task.

I don't think higher order communication between adults is that simple either. There's a lot of inference and deriving from implication that is prone to error.
The cat hasn't developed the same kind of talent for stringing words together, but has managed at least a couple of abstract things like 'mad' as a general unhappy word and 'where (item)' when looking for something.
Now the cats say 'eh-owww' whenever they see us, and also say the same phrase in different ways depending on what they want/need. It took us a while to work out the meanings of the intonations, but now we are pretty good at working out if it's a greeting, request, or just acknowledgement.
I'm not sure who trained who, but it seems to work. :D
Edit: Also, most animals don't point at things. If they are doing so, they are doing this especially for us.
We: "Hey, we want to share our science and philosophy and what we found out about the universe!"
Alien scientist (looking at some advanced gauges): "Look, its temperature rises."
