This Pokémon has lived with people since times long ago. It can sense when its Trainer is in the dumps and will stick close by its Trainer’s side.

Rockruff is so cute! I like how it’s Rock type without being overtly rock, though that begs the question why is it not Normal/Rock type.
I had a Rockruff in my Sun playthrough. He’s pretty good, fast and hits hard.
