free range pig ears Our dog demands her pig ears treat every morning – the brand we have been buying says “all natural” but my wife has her doubts. She suspects the pigs have lead miserable lives cooped up in some tiny confining cage, feed with hormones, anti-biotics and other unsavory chemical added as preservatives. After searching high and low I finally found some pig ears our dog can crunch on and we can feel less guilty at the same time.
