Hello, My older Tervuren loves to dig in my bedroom carpeting at night! I have tried exercising him before bed, and doing other things to tire him out, yet shortly after we go to bed, he starts digging in the carpeting! And this digging continues off and on throughout the night every time he moves to a different spot! My other Terv does not do this and sleeps comfortably the entire night. I have tried different things with him, and have not found a solution yet. The digging is driving me crazy! Any suggestions? Thank you!
