A rather tiny Yorkshire terrier name Lucy, from New Jersey, is the Guinness record holder for the world's smallest working dog. She weighs just 2.5 pounds.

Guinness World Records describes Lucy as a female micro Yorkshire terrier, measuring 14.5 cm (5.7 inches) tall on Nov. 28, last year. She is owned by Sally Leone Montufar of Absecon, N.J.

Guinness named Lucy the smallest working dog last week. That means tiny Lucy, who is only three years old, is the top dog, as she has beaten the previous record holder Momo, an eight-year-old chihuahua from Japan. Momo works as a police search-and-rescue dog, according to the Huffington Post.

While Lucy's job isn't as dangerous as Momo's, as a therapy dog, Lucy sure serves an important role. Lucy works through the Leashes of Love program, which is based in Cherry Hill, N.J., according to MSNBC.

MSNBC reported that two years ago, Lucy was headed for a pound when a woman brought her into the Paw Dazzle pet boutique in Smithville. But shop owner Montufar decided to keep Lucy.

NBC 10 Philadelphia reported that Lucy now visit hospitals, nursing homes and rehabilitation centers each week, working with children with disabilities and troubled youth.

She brings joy everywhere, Montufar told NBC 10, That she should go from being homeless to having a world record, it just shows you the potential that's there if you take a chance.
