These are the only pet supplements made with organically grown Barley Grass juice. Dogs and Cats instinctively eat fresh green grass, which is rich in vitamins, minerals and enzymes. The problem with eating whole grass is that each blade is covered with microscopic barbs that can irritate your pet's stomachs. Now you can give your pets these great nutritional benefits without those pesky barbs. The combination of Barley Grass and other natural ingredients tastes so good, your pets will think they are getting a treat.
