"Simple ingredients are the best ingredients. That's why Pet Center Inc. makes these highly nutritious chew treats from just one ingredient; whole grass feed beef hooves, which will bring your dog hours of chewing pleasure and better dental health. They're high in protein, low in fat, and are free of preservatives. Cow Bones are made in the USA. Dogs are much more than just pets—they're cherished members of the family. That's why PCI is devoted to making the healthiest, tastiest snacks and treats for your dog. A healthy human diet begins with whole or minimally processed foods, and dogs deserve the same standards. Some of Pet Center Inc. products consist of one single ingredient, and those that don't contain only recognizable ingredients. It makes a wholesome, delicious difference that your best friend will love."
