If one were to go about translating brain waves from dogs to meaning, we'd run into a big problem immediately: vocabulary resolution.

What I mean by that is we'll have a very limited number of words to which a dog's brainwaves can be translated to since we aren't able to understand them beyond their basic instincts of food, survival, fear, affection towards their owner etc.

There is just no way to go past what we have already observed by their behavior since dogs can't talk or write.

I do wonder how animals think. Perhaps this resolution would also be the theoretical maximum?

There are many dogs that have been trained to press buttons corresponding to words, in the extreme case tens/hundreds of buttons/words, and they can even construct rudimentary sentences. It doesn't seem insane to me that we could perhaps do a very rudimentary version of this for dogs, given a large enough training set.
