A Yorkshire Terrier from the US has entered the Guinness Book of World Records as the world’s smallest working dog.
The tiny animal, named Lucy, weighs just 2.5 lbs and is 5.7 inches tall. While she is not the smallest dog in the world, she is the smallest dog to work.
She helps the elderly by working in a programme called Leashes of Love, where she visits hospitals, nursing homes and special schools across Smithville, New Jersey,.
Sally Leone Montufar, her owner, said: "I said I bet she's not the tiniest, but I'm sure she's the tiniest therapy dog."
Ms Montufar also revealed how she almost didn’t take on little Lucy. She explained that a woman came into the pet boutique where she works with a number of dogs, saying that she had to take them to a shelter.
"She was so pitiful and lethargic I couldn't leave her.
"As any a mother would, I vowed to help her. I wasn't going to turn my back. The others looked pretty healthy but she didn't."
