The seven cowboys have been touring around London in the West End and crossing busy roads, leaving their horses at Boris Bike stations and chilling in London parks.
The marketing campaign is to launch the film which is released today (23 September), starring Denzel Washington, Ethan Hawke and Chris Pratt.
Commuters and tourists immediately took to twitter after seeing the cowboys on horseback with comments including: 'Cowboy commute in full swing this morning… watch out @TFL you’ve got competition for those Boris Bikes.'
Disney hosted a series of Finding Dory-themed events and activities at Westfield's two London shopping centres this summer to celebrate the movie's release.
