Rosie has a super sense of smell, even by dog standards. Unfortunately, one of the best smells comes from something dogs can't eat: the chocolate truffles her human family sells in their shop. Not one to settle, Rosie sets out to find a life that might suit her better, giving lots of occupations a whirl, but none pan out. Then she hears about a job as a truffle hound. It turns out there's another kind of truffle--the fungi kind, which grow wild underground--and they require a strong nose to sniff them out. Will Rosie finally find the perfect match for her unique talents? These truffles smell divine--so that sure would be a yummy solution!
