"Our Little Boyz are 100% all-natural beef esophagus, roasted for several hours to give it a crunchy and chewy texture, while bringing out all of the delicious natural beef flavors and then mesquite smoked for the final tail-wagging touch. Little Boys are a single ingredient treat and each one is about 10” long.\r\n\r\nNo refrigeration needed.\r\n\r\nAn order of Little Boyz is one piece of a beef esophagus chew dog treat, about 10 inches in length."
