BarkBone™ Natural Instincts Nylon Pig Ears offer a healthier and cleaner alternative to real pig ears. Designed for aggressive chewers, they mimic the natural look and feel of a pig ear. Infused with the irresistible flavor and scent of delicious bacon, this flavor permeates the core of each ear. Crafted from premium artisan nylon, the unique shape of our pig ear helps pets scrape plaque and tartar from their teeth, promoting good dental hygiene. The premium nylon is FDA-compliant, non-toxic, and non-allergenic.
