Quite incidentally, very recent research reports that "dogs think more like humans than chimps do."

The test consisted of whether you could point at something and have the responding animal realize you wanted them to look where you pointed. Some breeds of dogs do an excellent job of responding as you intend. Chimps, in the tests, didn't do quite as well.

The assertion that the dogs responded "more like humans" may be open to some question, as when I'd point and say "Look at that" one ex-wife would carefully examine the end of my finger, and never thought of looking outside where I pointed. (But note she is an ex-wife.)
