Query: Good, safe, chew

These are the ultimate in edible chews, in my opinion. They are safe, as large chunks won't break off, and according to my dog, insanely delicious. She's a large German Shepherd and it takes her about 20 minutes to eat a 12" bully stick. That's pretty amazing to me, because she can demolish any other chewy item in less than five minutes normally (which defeats the purpose of the chew-to keep you dog busy!). When I give her one of these, I stick it inside a 10" sterilized bone, so a little sticks out both ends. She hates the sterilized bone, but with the bully stick inside, it's magic. It takes her about 40 minutes to get it out and then eat it. They are expensive, but I think they are worth it, as an occasional treat.
