What list is your dog on? Crumps' Naturals Naughty Treats are our NEW seasonal treat offering made for the dogs on both of Santa’s lists. Made from just beef lung, and looking eerily reminiscent of the lumps of coal the grinch would love, these treats are a simple way to show them both your love and your years’ worth of displeasure. Changed your mind and want something nice? Or at least something for those loving moments where they’re acting cute this Christmas?
