My dog Sash is a chewer, and both dogs like toys. But rawhides = a great way to pay $6 to see a small Shih Tzu with a large lump in her body like a snake that swallowed a goat. Then I found out they made these chicken-and-veggie "rawhides" that taste like peanut butter and are "99% digestible."
Ten minutes later, that's Sash's on the left. I've never witnessed it, but I think she can unlock her jaws.
