The phrase “working dog” is normally associated with something big and robust. Like a German Shepherd working as a police dog, or a Labrador helping someone hard of seeing. Sometimes good things come in small packages; Lucy is a Yorkshire Terrier who recently set a Guinness World Record as the world’s smallest working dog.
Lucy weighs a mere 2.5 pounds and works as a therapy dog. She visits hospitals, nursing homes, and rehabilitation centers, and works with children with disabilities.
The previous record holder was named Momo, and that is an eight-year-old Chihuahua who works as a police search-and-rescue dog in Japan.
