'My Big Fat Greek Wedding' star Nia Vardalos has a Labrador Retriever named Manny. Vardalos credits Manny for her newly toned figure, which was revealed in 2009. Both Vardalos and Manny lost weight together, calling it the 'Manny 6-Lb. Challenge' after each of their doctors ordered them to shed some pounds.
