Thanks for the suggestions, Pawla—we are trying to get in as much activity as possible before we leave him (long walk plus playtime). He’s usually ready to pass out at that point, so I’m hopeful that as his familiarity with the xpen and his surroundings grow, so too will his ability to give in to his tiredness, even if we aren’t there. We have two cats that he is trying desperately to befriend....they aren’t particularly enthused yet, but fingers crossed. At this point an additional dog companion probably isn’t a possibility. Right now he has free rein of the downstairs living/kitchen area when we are there (we’ve got baby gates at both staircases). We may try the leash suggestion when we are upstairs, as otherwise one of us is bound to that area, too, unless we are prepared for him to scream until we come back down (and we’re not yet comfortable leaving him with free rein unsupervised). yes the chewing the leash when we’ve kept him tethered to us is an issue so we’ll definitely try the bitter apple technique or look into a chain one (though I suspect he’d try to chew that too—haven’t found anything he won’t chew yet!)
Hi Tanya— I think you’re referring to my comment about him being in his crate in a well trafficked area during the day—that was mainly when we were working to get him more comfortable with the crate in general, which appears to have worked. He is not confined when one of us is home, except for the occasional brief period for safety, (I.e only one of us is home and needs to leave the main living area temporarily/ people are coming and going through the front door, etc).
