Help

My malinois keeps destroying his bed, it is starting to get cold now and he has to sleep outside as he is a guard dog for the property but he keeps shredding up any bed or blanket we give him. He is often in the house and never destroys anything but we can’t leave him more than a night with a blanket or a dog bed as he destroys it. I have tried leaving him with a toy that he can chew on and waking up early and removing the bed, which did kind of help but woke up this morning to the new bed in pieces again. Does anyone have any advice? He has a kennel and a solid bed that he hasn’t destroyed and I’m sure he is probably fine with his thick coat I just feel so bad sending him out in to the cold each night with nothing! 🥲
