I have a greyhound. If she is not exercised enough she will find a way, but so far it’s cost me about $4500 in breakage. For instance she discovered making a kick turn at the end of the hall could lead to crashing through drywall, so then she tried to see how high on the wall she could crash through. Also she ran around the bedroom 56 times in a row, only stopping when the bed frame broke. But yeah, sleeps all the rest of the time.
