I think the wild side is anchored quite deeply.
Spending some time everyday with Buddy, building positive personal capital, is what, in my opinion, will keep him manageable, half-way civilized during the winter. I think he is more likely to mind you when you tell him "No" or redirect him if there continues to be playful interaction between you and the family. Otherwise, he may really tear things up or become very unhappy about being constrained. I think play is an intrinsic part of their natures.
Otherwise I think both of you will become very aggravated with each other through the long winter.
