First off, I absolutely love all of Bernies Best products because of the high-quality, no filler or junk, ingredients. I've been feeding my Bernese Mountain Dog, Odin, Charming Chompers for over a year now and have seen a big difference in the lack of tartar and plaque buildup on his teeth, especially molars and canines. We have a routine that he gets his daily Chompers when he comes home from work (he goes to work with me). He goes directly to the pantry and stares at the bag and won't move until he gets his dental chew. When I give it to him his mouth quivers with excitement!
