The peaksNpaws All-Natural Large Water Buffalo Horns Dog Chew Treats are one of the best quality horns you'll find in the market, sourced from 100% free range and grass-fed buffalos. There is nothing man-made here, no preservations or hormones. Due to their unique nature horns can vary in size, shape, color, and weight. These buffalo horns are high in protein and low in fat. The bone core is covered by a resilient sheath made of keratin, rich in vitamins and minerals. They are also high in calcium and phosphorus, which are vital for healthy, strong bones and muscles. As a result, buffalo horns can be an excellent addition to your dog's diet. The main health benefit for buffalo horns is their contribution to dental care. These dog treats promote good hygiene, by scraping off plaque that builds up on the teeth and keeps breath smelling fresh due to reduction in plaque.
