Though often mistaken for a Tennessee Walking Horse, his sire was a Thoroughbred and his dam a grade (unregistered) mare who, like Trigger, was a palomino. Movie director William Witney, who directed Roy and Trigger in many of their movies, claimed a slightly different lineage, that his sire was a "registered" Palomino stallion, though no known Palomino registry existed at the time of Trigger's birth, and his dam was by a Thoroughbred and out of a "cold-blood" mare. Horses other than Golden Cloud also portrayed "Trigger" over the years, none of which were related to Golden Cloud, the two most prominent of which were palominos known as "Little Trigger" and "Trigger Jr." (who was a Tennessee Walking Horse listed as "Allen's Gold Zephyr" in the Tennessee Walking Horse registry). Though Trigger remained a stallion his entire life, he was never bred and has no descendants. On the other hand, Roy Rogers used "Trigger Jr."/"Allen's Golden Zephyr" at stud for many years, and the horse named "Triggerson" that actor Val Kilmer led on stage as a tribute to Rogers and his cowboy peers during the Academy Awards show in March 1999 was reportedly a grandson of "Trigger Jr."
Film career 
Golden Cloud made his movie debut as the mount of Maid Marian, played by Olivia de Havilland in The Adventures of Robin Hood (1938). A short while later, when Roy was preparing to make his first movie in a starring role, he was offered a choice of five rented "movie" horses to ride and chose Golden Cloud. Roy bought him that same year, 1938, and renamed him Trigger for his quickness of both foot andmind. Trigger learned 150 trick cues and could walk 50 feet on his hind legs (according to sources close to Roy Rogers). They were said to have run out of places to cue Trigger.
Trigger was ridden by Rogers in many of his motion pictures, becoming much loved by the youthful audience that saw him on film and in Rogers' 1950s television series with his wife Dale Evans, who rode her trusty buckskin Quarter Horse Buttermilk.
Roy Rogers made many personal appearances with Trigger in tow. More than once Roy escorted Trigger up 3-4 flights of stairs at hospitals to visit with sick children, according to his autobiography "Happy Trails."
Death and legacy 
After the original Trigger (Golden Cloud) died in 1965, Roy Rogers arranged for Everett Wilkensen of Bischoff's Taxidermy in Los Angeles, CA (now Bischoff's Taxidermy and Animal FX in Burbank, CA) to preserve/mount the horse. The hide was professionally stretched over a foam likeness of Trigger, and the resulting mount was put on display in the Roy Rogers and Dale Evans Museum when it opened in Apple Valley, California in 1967. The mount was later moved with the museum to first Victorville, California in 1976, and then to Branson, Missouri in 2003. In 1967, it was discovered that, contrary to the The Prevention of Food Adulteration Act of 1954, Trigger's horseflesh was sold to unscrupulous southwest eateries by butcher John L. Jones, a crime for which Jones was sentenced to five years in prison.
At some point, a 24' replica of a rearing Trigger was produced to sit atop the Roy Rogers Museum in Victorville. The 1,300 lb. replica could be seen from the freeway and served as a landmark until the museum closed and moved to Branson. When the fiberglass replica of Trigger was being made, Rogers was approached by the owners of the Denver Broncos. Rogers allowed another statue to be made and then broke the mold. "Bucky the Bronco," Trigger's twin, stands above the south scoreboard of the Denver Broncos stadium.
After the closing of the museum in 2009, its contents were placed at public auction on July 14–15, 2010, at Christie's auction house in New York City. Trigger's preserved remains sold for $266,500 to television channel RFD-TV, which plans to start a Western museum. Bob Tinsley, a Victorville developer who had built Roy Rogers' home in nearby Apple Valley, bought the fiberglass replica in April 2010. Tinsley's plan is to make the statue a part of historic Apple Valley Village. He explained, "I just couldn't see letting him go anywhere else."
