We just received a box containing Vivamune Health Chews and our dogs were climbing right into the box to get to them! Containing OxC-beta (oxidized beta carotene) these treats support the immune system and promote healthy joints and skin. Our dogs love these tasty, one-a-day treats that are available in both large dog formula as well as a small dog formula. Check them out at vivamuneforpets.com.
