Cisco *loves* his rope bones...but the worst he does is to carefully bite the ends off - down to the knot - and leave those little threads all over the house.
He did, however, pretty much completely destroy a set of puppy chew keys this week. The ring is still there, but the keys have no ends.
Gypsy hasn't shown much interest in her rope bone. For her, it's gotta be a sweeky. The frisbees have numerous holes in them from her retrieving them. She doesn't have a soft mouth.
