It isn't an either/or situation-- turns out the intelligence we attribute to a social animal is related to our ability to communicate with it.. which shouldn't seem weird at all. It's not clear we have a good understanding of 'intelligence' /outside/ of the social context. The word itself just means 'understanding'.. and 'understanding' is just the read end of 'communicating'.
Coming up with a definition of intelligence that doesn't need an observer/understander is an interesting exercise; kinda demonstrates my point inasmuch as the word stops taking on a unified meaning and we find ourselves grasping around for the real Y-axis.
That said I think the head-tilting somehow increases cognition for a second, and the social signalling is an added benefit. Maybe it's a blood flow or cerebrospinal fluid thing. Big brains use a lot of blood oxygen and glucose while they're working. But that's just me BSing.
Regarding the cane corso-- fighting/guard dogs don't do the head tilt, but they're not gonna learn the words either...
Also, dogs evolved to communicate with dogs for ~(10E7) years, then learned to communicate with humans for ~(10E4) years. I think they mainly speak dog.. well, not dog, but puppy; the common path of mammal domestication being through juvenilization.
