Yeah I think that is a little weird. Pit Bulls are some of the most destructive dogs I've seen, of course they don't have them there. Not all are destructive in the least bit but some certainly are. Mine have chewed trees, guaranteed "chew proof" dog house, kongs that are supposed to be tough, the similar "pit bull tested" guaranteed rhino toy, tons of other things.

I guess it would kind of depend on the destruction. Chis can be bad little chewers and while they don't usually destroy such big things it could be an expensive item. Our pit breeder friend who passed away had a Chi who would chew and chewed up the house phone cord a few times. If they chewed the cord off something very expensive that'd be a big claim.
