“Nothing changes, same leash, same location, etc.” What changes is her state of mind. The scenario you describe has three possibilities.
- She is in a fearful or aggressive state of mind when you go to take the leash off. To alter that you have to first learn to recognize and understand the signs she is in that state of mind.
- She is in a playful state of mind and considers this fun. In which case, if you then go up the stairs and make yelping noises, she may consider it a great game.
- She considers herself the leader and you the easy push over that she can manipulate.
Which it is, I don’t know without seeing it in person. No other possibilities spring to mind.
Basenjis are an unusual breed, but more importantly they range from easy going to incredibly challenging.
I would start with at least five miles of walks each day, short leash and with you in full control. Preferably at least three walks, morning noon and evening.
