Antlerz are a totally new, 100% natural, mineral rich, long lasting dog chew. The new chew is made from a natural material that is rich in minerals, does not splinter and comes from a completely renewable source: Deer Antlers! Wild deer shed their antlers once a year as part of a natural process, after which the deer re-grow another set. These shed antlers are gathered by ranch workers and transported to QT Dog's manufacturing facility. The antlers are cut to the appropriate size, cleaned, and packaged to produce ANTLERZ™ brand dog chews. ANTLERZ™ hold up substantially longer than most traditional chews made from plastic, bone, or compacted starch. A minerals analysis of ANTLERZ™ show high concentrations of calcium and phosphorus, with trace amounts iron, zinc, and sodium. Unlike processed livestock bones ANTLERZ™ don't chip or splinter when they are being used by even the most aggressive chewing dogs. A dog's chewing action grinds ANTLERZ™ down slowly. ANTLERZ™ are a 100% natural, mineral rich dog chew that contains no plastics, no petrochemicals, no empty starches or artificial flavors. By the way, these chews were recently featured on the "Today Show" as a great new dog product!
