In November 2013, Dousa was called up to the United States national floorball team for their 2014 World Floorball Championships qualifying campaign after impressing national team scouts at a floorball tournament in Westchester, New York. He made his full international debut for the United States on January 31, 2014 in a World Championship qualifier against Jamaica, scoring one goal and providing one assist in a 27–0 win. He won his second cap on February 2, 2014 in a qualifier against Canada, helping the United States clinch a spot at the 2014 World Floorball Championships through a 5–2 win. Despite contributing to United States' qualification for the World Championship, he was not selected for the final tournament held in Gothenburg, Sweden in December 2014.
