What can happen if a Collie mix owner does not clearly step into a leadership role?

Answer

The dog may attempt to fill that void, potentially leading to jumping or bossiness

These dogs often try to manage their environment; if the human leadership role is not clearly established, the dog might attempt to take charge, resulting in behavioral issues like jumping or becoming bossy.
