Simple ingredients are the best ingredients. That's why Pet Center Inc. makes each of these highly nutritious chew treats from just one ingredient; dehydrated beef lungs and dehydrated duck breast and dehydrated chicken breast. They're high in protein, low in fat, and are free of preservatives. 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.
