I was just reading in a dog mag (Bark, I think) about Solid Gold putting out a cinnamon bone - it allegedly takes care flea, ticks, mosquitoes. Anyone heard of using cinnamon? I cannot give Gracie those bones as they have barley in it so if you've heard that cinnamon is reliable, how much cinnamon? Would I just sprinkle it on her food? Just use the regular baking cinnamon (obviously NOT cinnamon sugar.....just what CRAZY Gracie would need).
