Weird, right? Your dog won't care two shakes about sniffing a scented Sniff Pet Candle ($28). He voluntarily smells his own butt! But the fine print reveals that the candles are infused with natural aromatherapy oils that promote good health in canines. The scents are for your benefit. Light a candle to hide your pup's current got-into-the-garbage-again stink and help settle his tummy after that melted carton of freezer-burned ice cream.
