That's funny Kevin, our Pyrenees did the same thing to a mountainsmith pack. It seemed like a well made pack but she got going through some tight brush after a coyote and came back with a messed up pack. I'd suggest to the OP going to a shop that sells multiple brands with your dog in tow. Different packs fit different dogs differently, a brand that fits my dog like a glove might not fit your similar sized dog at all.
