We can see it in most of us humans. Most homininae, including gorillas apes and humans, act generally similar even if we look really different. We laugh in the same way, we stay in families the same way, we play the same way, and generally have similar visceral, and knee jerk reactions to the same general things... And I also want a way to understand how different my harpies and humans and biped dogs would act. I know general quirks about my fantasy species, like that they snap their mouths when they are angry, and literally bark at times when threatened. They have long tongues and have a snout, similar in size to a bulldogs mouth but smooth. They generally love doing things in massive packs, similar to most bipedal dogs of today that live in caverns and holes. Think a mix between the wolves den and the meerkats and prairie dogs. My bipedal dogs live in insanely long holes and caverns that they dig.
They might live in caves and eat like cavemen, but they are at a metal age level of advancement due to the insane heat and depth they live in, thus making it easier to have access to metal. They know how to dig really well by nature, and know how to use magic to bend metal to their advantage. Metal is easier, and more permanent than the magic substance they use. They do have social standards and can, and do exist and act in regal type places, even if they are discriminated against and called dogs. They aren't feral by nature; they have brains akin to humans, and can change and think and have complex thought processes just like humans. They believe in a God of Void and Holy(the magical substances) like everyone else in this world and they do have rituals and gatherings. So they are generally above cavemen level of advanced.
My main question is mostly just like, am I missing anything? Is there some weird fact about dogs that I am missing in my explanation that I should take into account when designing general behaviors? I know to not have them ALL act like dogs. Don't worry, they all have their personality and each are just as diverse in actions as humans are. I just want to get nature out of the way, because believe it or not, humans do all generally have a specific nature to them that makes them human, aside from physical characteristics, even if it is small.
