Several factors, such as country of origin, drying time, and the individual bull, can contribute to these differences. Our bully sticks contain no chemicals, bleach, or fillers, and they are entirely natural. Therefore, you may notice various features within the same bag, but rest assured that the product is still safe to consume.
