Police said an ambulance responded to an Aspen hotel on Saturday morning where a man was bleeding from facial injuries.
The man accused Dallas of assaulting him.
Dallas will face a judge on Jan. 22.
The 24-year-old posted his booking photo on Twitter, along with a comment indicating that the incident was a case of self-defense.
