When Baxter--First Pup-was a baby, he destroyed my $300 glasses by knawing on the lenses, right in my line of vision. He also chewed up the cable to my Comcast Modem, destroyed every corner of molding and doorframe in my BRAND NEW home, and chewed on the posters of my $3000 bed. Oh, and he peed on my $1000 matress, that was easily cleanable, but the feather bed on top of the mattress had to be professionally cleaned. I think Baxter owes me some money
I really felt like he was the devil dog sent to terrorize me from HELL!
He is now 3 years old, and it is very rare he gets into anything, besides dirty clothes and paper--he just can't resist them.
Everything he did, just like everything your dog does, was MY fault, for not putting things away, and for not putting him in a secure place when I couldn't watch him. You really need an x-pen. You can put his kennel, pee pads, and food dishes inside there, and he will have everything he needs.
IMO, it is dangerous to leave your tog tied to anything when you aren't supervising him. He could get choked easily.
