Some coats may have fur from dogs The investigation began after the society got a tip from a consumer who bought a coat with trim labeled as faux fur that felt real. Leppert and her team began buying coats from popular retailers and then had the coats tested by mass spectrometry, which measures the mass and sequence of proteins, to determine what species of animal the fur came from. Of the 25 coats tested, 24 were mislabeled or misadvertised. Three coats from Tommy Hilfiger's Web site ShopTommy.com, Nordstrom.com and a coat from Andrew Marc's MARC New York line sold on Bluefly.com contained fur from domesticated dogs. The others had fur from raccoon dogs a canine species native to Asia or, in one case, wolves. The single correctly labeled coat was trimmed with coyote fur, but it was advertised as fake. I don't really care if people wear fur or not, but I think they should KNOW that's what they're buying!
