Sandra Devall has found a little friend in 5-month-old puppy Grace – really little.
Measuring just 6 in. long and weighing 1 lb., 6 oz., Gracie could be the smallest dog in the world, according to the U.K.’s The Sun. The tiny pug weighs 4 ounces less than Brandy the Chihuahua from Largo, Fla., who is the current Guinness World Records holder for smallest living dog.
