Destructive Chewing

Owner walks in, couch destroyed. Dog happy in the mess. Owner laughs, pets the dog. Dog just got rewarded for the destruction.

This is an energy problem. Working dog, no morning walk. Wear him out first — every single day.

The fix: firm "no" in a deep voice, three-second pause, wait for him to actually calm. Then a proper chew toy. From a young age, you're teaching him what he can chew and what he can't.
