According to federal regulations, there are several quality categories for meat. These include Prime, Choice, and Utility grades. Prime is the best and, not surprisingly, the most expensive. Choice is next—pretty good quality but not as excellent, or as expensive, as Prime. And then there is Utility grade, which is suitable for dog food. (Although dogs generally discriminate keenly as to whether or not they have been fed, beyond that, most don't seem to be particularly fussy.)
