"These are one of my favourite dog treats. I've fed them to both of my dogs and bought and fed them to family members' dogs and dogs I "dog-sit" as well - every dog LOVES them.
I don't know whether they actually work long term at keeping "doggie breath" at bay, but they smell a whole lot better than some other strong smelling flavoured treats and don't leave the dog's breath smelling like chicken, lamb, etc, for right when they greet you and "give you kisses!"
I recommend them for greeting dogs - give them one of these and then get your kisses and you won't have stinky breath in your face!"
