Well, Bulbapedia says "Lucario are primarily carnivores, hunting their prey in packs", but it also says: "It usually lives deep in mountains very far from people to improve their skills."
.
I'm guessing that wild Lucario act differently to those that have been evolved alongside a human, because it also states "Lucario is considered to be prideful, and is extremely loyal to its Trainer."
.
But yeah, canon heights aren't always considered in a lot of media, because of things like Charizard is 5'07", so it'd be impractical and cruel to fly on a dragon smaller than most people.

That's usually why I don't like the cannon hight. It says Charizard is the shortest out of Dragonite, Garchomp, and Charizard. Although they all appear around the same. Plus... How is gardevoir only 5'3
My fav pokemon is the Shinx evolutuions tho
