Oppy is going to be 9 months old on Saturday and I was thinking it may be time to start working on not using his crate while we're at work (he'd be alone for approximately 6.5-7 hours). We've tested leaving him alone while we go to the grocery store which usually lasts about an hour or so and he's been doing really well as long as we puppy proof everything (make sure there's nothing on our desks that he can reach/steal/shred). But 6.5 hours is a lot longer than what we've currently tested him at, I'm just worried if he can hold his bladder that long. Any suggestions on the topic? Or should we just try leaving him out and hope for the best?
