What was the name of the family dog in the TV series "The Waltons"?

"The Waltons" is an American drama television series about a family in rural Virginia during the Great Depression and World War II. It was created by Earl Hamner Jr., based on his book Spencer's Mountain and the 1963 film of the same name. The show began in 1972 and aired on CBS for nine seasons. After the series was cancelled by CBS in 1981, NBC aired three television movie sequels in 1982.

The story is about the family of John Walton Jr. (known as John-Boy): his six siblings, his parents John and Olivia Walton, and paternal grandparents Zebulon and Esther Walton. John-Boy is the oldest of the children (17 years old in the beginning), who becomes a journalist and novelist. John Sr. manages to eke out a living for his family by operating a lumber mill with his sons' help as they grow older.

The family income is augmented by some small-scale farming, and John occasionally hunts to put meat on the table. In the simpler days of their country youth, all of the children are rambunctious and curious, but as times grow tough, the children slowly depart from the innocent, carefree days of walking everywhere barefoot while clad in overalls and hand-sewn pinafores, and into the harsh, demanding world of adulthood and responsibility.

The family had many animals and Reckless was the name of the Golden Labrador who appeared in the first eight seasons of the show. Their other pets included Blue the mule, Chance the cow, Rover the peacock, Lance the deer and Myrtle the goat.
