Aristopets Pig Ears are a great All-Natural alternative to rawhides. These flavor packed chews are fully digestible. Pig ears are rich in many minerals such as, magnesium, zinc, calcium, and collagen. Collagen that is in your dog's body is what is responsible for the level of elasticity in his joints, tendons, cartilage, skin, and ligaments. It is also the protein that determines the strength of your dog's hair, bones, nails, and teeth, so it is important your pooch is getting enough collagen in their diet. Pig ears are made up of cartilage and that is a natural source of chondroitin which can help support joint health. The fur is not digested and passes through the digestive tract, cleaning the side walls and the colon. While your dog is enjoying chewing on their pig ear they are also receiving excellent dental health. Aristopets Pig Ears come from a local, fresh farm and are dehydrated right here in our pet store. There are absolutely no added chemicals, fillers, colors, or preservatives.
