Exactly.No because genetics have a lot too do with it, puppies are not blank slates
its for the same reason why you donāt except a golden retriever to herd or a border collie to naturally retrieve
and some like aggression only show up as the dog matures
But my golden does know how to herd and i didnt teach him. Its so hard walking in a group cause he tries to herd if someome walks to far away.
