Rollover's Salmon Stuffed Bones are natural, cleaned beef femur bones that are stuffed with Rollover's delicious, natural dog food and carefully baked to be a long-lasting treat for your dog. Beef bones are the hardest bones available so they're long lasting and stand up to power chewers! The salmon stuffing will entice even the pickiest pooch to gnaw on this bone  to clean their teeth. Each bone is approximately 5-6" in length, 2" in diameter, and individually shrink-wrapped in a resealable bag to ensure freshness.
