Whimzees is offering a free sample of their Whimzees Natural Dental Treats. These treats have no artificial colors or flavors. They are GMO free, gluten free, and grain free! I just requested a sample for my little dog. He usually gets sick from treats but these sound pretty clean for his sensitive tummy. Click this Whimzees Natural Dental Treats link to get this freebie! This is available while supplies last!
