Ingredients: beef, that’s it! We add no fillers, preservatives, grains—no nothing.  Just beef.  Our beef has no hormones or antibiotics and is sourced and made all in the USA. Wiley’s Beef Jerky is produced from the eye of the round from the highest quality humanely raised beef. We source our raw materials from healthy, sustainably farmed beef that is free of hormones or antibiotics. We lightly process it and use the EcoPawz dehydrating technique so that we don’t have to add any preservatives. Everyday treat. Portions easily for training. Great for hiking.
