Lucky was originally a man was homeless when he was approached and recruited to become a skinwalker, and he was told that being bitten would make him strong and fast.
Shortly after being turned, Lucky found a family and posed as their pet dog - shortly after he found this family, he grew fond of them and killed anyone who indirectly or directly threatened Mandy or her son.
He lives with Mandy, her son, and her boyfriend, Cal Garrigan. He grows attached to Mandy and kills anyone who threatens her and her son: their landlord because they are behind on the rent, Cal's brother because he was violent towards Mandy, and eventually Cal, who is a drunk.
After being hit by a car while in dog form as he fled from Sam, Sam and Dean take Lucky from the animal hospital, binding him in rope and silver chains to restrain him. He reveals that there are about thirty skinwalkers who have been recruited and are living with families as pets. On a signal from their pack leader, they will infect their families, thus recruiting more skinwalkers. He tells Sam and Dean that there are packs in many other towns, but he knows nothing of the Alpha Skinwalker.
Lucky leads Sam and Dean to the Pack Leader, but he has kidnapped Mandy and her son and threatens to kill them unless Lucky turns them. Sam and Dean open fire, and all the skinwalkers are killed except Lucky, who, although shot with a Silver bullet, escapes.
Lucky, in human form, goes to visit Mandy and tells her how he appreciated her kindness, but she calls him a psycho tells him to leave. Lucky transforms into a dog and dejectedly walks off.
