A cute face and an unusual talent combine in the Italian lagotto romagnolo. According to the Lagotto Romagnolo Club of America, this little cutie is bred to sniff out truffles -- the expensive underground tubers. The dog has a curly, dense coat that sheds off water and keeps its skin dry, and they weigh under 35 pounds. They require some exercise and mental challenge, but they are easily trained and healthy. Prices vary, but a trained truffle hunter can cost as much as $7,500.
