Beef chins...I have never heard of that being on the market. As for rawhide, I strongly discourage giving rawhide to dogs. I heard of a dozen or so dogs choking and dying from rawhide. There are other (and safer) chew things, including the booda velvets (corn starch bones), and the pig snouts and beef chins (although gross sounding) that stuff is less of a hazzard then rawhide. Just understand, there is a reason your vet hates rawhide!
