Willson spent just $20 to make the ad - for treats to get a friend's Great Dane to keep posing, according to Doritos.
TiVo also ranked the ad No. 1, based on viewers' behaviors with the company's playback service.
But wait. Checking the late-morning ranking on the USA Today list, a different ad took over the No. 1 spot - "Sling Baby," another consumer-created Doritos ad, in which a grandma slingshots a baby toward a teasing brat to snatch away a bag of chips.
"Doritos: Man's Best Friends" had fallen to third, behind a Bud Light ad about a rescue dog named Weego, who fetches beer everytime someone says, "Here, Weego."
TiVo's No. 2 was the M&Ms "Ms. Brown" ad - about a talking candy mistakenly thought to be naked because her shell is chocolate colored, "Sling Baby" was third, followed by a Pepsi ad featuring X Factor winner Melanie Amaro dropping King Elton John into a dungeon.
The M&Ms ad was fourth in USA Today's poll, followed by "Volkswagen: Dog Strikes Back" - about a heavy pooch that works out and diets to finally fit through the dog door and go chase cars. That was also TiVo's No. 5.
