Lassie, the heroic dog that stole the heart of America and millions of fans abroad, is arguably the most famous four-legged movie star of all time. In reality, there have been numerous dogs to fill her role, the vast majority of whom are direct descendents of Pal, the very first canine actor to play the part.

Lassie’s classic character first appeared in “Lassie Come-Home”, a short story by the British-American author Eric Knight. The story was later expanded into a full-length novel by the same name, and then made into the first Lassie film in 1943. The film focuses on Lassie, the beautiful and loyal dog of a Yorkshire boy, Joe. When economic hardship forces the family to sell the collie, neither boy nor dog can withstand the separation. The film follows Lassie’s escape and exceptionally difficult trek home to her boy. It was wildly popular and received great praise from critics.

Several other films featuring the canine hero were produced shortly thereafter, beginning with "Son of Lassie" in 1945. In "Son of Lassie", Pal played the role of Lassie’s male pup, Laddie. In the film, Joe joins the Royal Air Force and departs for training school. Laddie loyally follows his master, eventually stowing away on a plane headed for Nazi-occupied Norway. Joe and his dog depend on one another as they attempt to find friendly territory, with the Nazi forces in constant pursuit.

The next in the series, "Courage of Lassie", was released in 1946. The lead canine role – “Bill” - was played by Pal; despite the title, the fictional character Lassie did not appear. The audience is first introduced to Bill when he is separated from his mother and grows into adulthood in a forest. After being injured by a hunter, a compassionate shepherd and a young girl named Kathie nurse him back to health and teach him to be a sheepdog. Sadly, Bill is hit by a truck and sent to a distant animal hospital, where he remains unclaimed for several months before being sent off a War Dog Training Center. Bill (renamed Duke) performs brilliantly, but is driven into aggression by stress and injury. An intense hearing ensues to determine whether or not Bill should be put down for his aggression.

Shortly after, Lassie also received her own radio show, which aired until 1949.

Next in the MGM film series was "Hills of Home" in 1948. The plot follows the good-natured Dr. William MacLure, who buys a beautiful collie dog to be his companion and assistant, only to find that the dog – Lassie – is terrified of water. In his professional travels the doctor is compelled to cross many streams and bodies of water to reach his patients, so he takes it upon himself to help Lassie overcome her fear and learn to swim. In the end, the dog’s love for her master proves to be a powerful force, more powerful even than her pervasive fear of water.

"The Sun Comes Up" and "Challenge to Lassie" were released in 1949. The former follows a bereaved widow as she slowly comes to terms with the death of her husband and begins to extend her love back to her courageous collie and the boy she has befriended; the latter documents Lassie’s plight as she loyally remains by her master’s grave, in spite of laws that dictate that she must be put to death if she is not claimed.

Pal’s seventh and final film billed as Lassie, "The Painted Hills", was released in 1951. In the film, Lassie is the devoted companion of a kind prospector who is killed in cold blood by his greedy partner, Lin Taylor. Suspecting that the dog knows what he has done, Lin tricks Lassie into eating poisoned food. After nearly dying, Lassie returns to exact her revenge on her master’s murderer.

It wasn’t long before Lassie had a television series to add to her impressive portfolio. The series was met with favorable critical reviews and received two Emmy Awards within its first years. Pal appeared as Lassie in the two pilot episodes before retiring and leaving the remaining work and the stage name to five of his descendents: Lassie Junior, Spook, Baby, Hey Hey, and Mire. All five were trained by Pal’s owner and trainer, Rudd Weatherwax.

Over the show’s nineteen seasons, Lassie enjoyed several different contexts. The first ten seasons took place in a small, isolated farming community – first with eleven-year-old Jeff Miller and his family, and then with seven-year-old Timmy Martin and his adoptive parents. Lassie then found adventure in the wilderness with a small band of Forest Rangers before going a full year without human leads. Finally, Lassie settled down in a children’s home for the duration of the final seasons. The show was canceled in 1973 after enjoying nearly two decades on air.

Other series waxed and waned throughout the 1980s and 1990s, including "The New Lassie". The most recent series ran on Animal Planet from 1997 through 1999. In 2006, a British remake of "Lassie Come Home" (titled simply Lassie) was released.


Although Lassie’s character is a female collie, the role of Lassie has traditionally been played exclusively by males. Male collies tend to maintain a thicker summer coat, which is perceived as more attractive on-screen, and they also tend to be larger – a child actor can work with a larger dog for a longer period time before “outgrowing” him.

Pal’s bloodline continues to flourish, with many fans demanding that the role of Lassie continue to be played by his direct descendents. Eight generations of Pal-lined dogs played the role up until the late 1990s, all of whom were trained by Frank, Rudd, or Robert Weatherwax. Classic Media acquired the Lassie trademark in 2000, and terminated its contract with the Weatherwax family in 2003. Bob Weatherwax continues to breed and train “Lassie dogs” from Pal’s bloodline. Lassie’s character has appeared in radio, television, film, animated series, comic books, children’s novels, and fan merchandise, and will likely continue to do so.
