Hola I am Ena :) , from Peru, now living in Calif. I am owned by a basenji mix named Zorro-BaBa. He is 2 1/2 years old. I rescued him when he was six months old, he was a stray with a dislocated hip. He is now the love of my life.
Welcome to the Forum. It sounds as though this 'protectiveness' has been going on a long time. I agree that probably it would be best to get help from a behaviorist but make sure that they have experience of Basenjis. In the meantime keep him away from your guests. It's possible that he's stirred up by the excitement so it's best to try to keep him calm when people are around.
