Max is fitting in well. He is eager to please, exuberant, loving and needy.
Jake is calm, independent, astute and loving.
Windy is assertive, egocentric, manipulative and loving.
Somehow all this is working so far.
People learn about dogs needing a pack leader. Jake fulfills that role, and Windy makes sure Max knows he is number three. However, no dog bullies the other.
People could learn a great deal from this.
