The 4-week-old lamb lives in Tauranga with six dogs, a cat and an older sheep named Coco. But of all those animals, owner Katrina Thompson says Lucy is a truly special one.
Born last month in bad weather, Lucy suffered joint-ill, an infection in the joints that meant that she couldn't walk or even lift her head.
"After three days in the house, she managed to stand for the first time and has improved slowly ever since," proud owner Katrina Thompson told the Herald.
"She needed three weeks of antibiotics to clear the infection which has left her with arthritis in a front knee and her back hip. So she still sleeps in the house with us and is doing well with toilet training but wears a nappy just in case of an accident," Thompson explained.
"She has no idea she is a sheep at all. She eats and sleeps with the dogs and comes out for walks now that she's a bit older."
Every night, Lucy cosies up on the sofa with the family's six dogs, who she sleeps with.
The more time goes by, the more Lucy the lamb learns from her canine companions and the family she lives with.
