Initially leaving his home country at the age of 16 to pursue playing opportunities overseas, Dobeš joined the Topekta Pilots of the North American Hockey League (NAHL).

[17] The same day, team head coach Martin St. Louis announced that Dobeš would make his NHL debut against the Florida Panthers at Amerant Bank Arena on December 28.

[20] Additionally, Dobeš became the seventh goaltender in league history to record a win versus the defending Stanley Cup champion in their NHL debut, and the third to have done so via shutout, after Hal Winkler and Daren Puppa.

[23] Improving his record to 3–0–0 with a 3–2 overtime win over the Washington Capitals on January 10, he matched Bob Perreault as the only Canadiens goaltenders to allow three goals or fewer through his first three career starts with the team.

[24] A week later, Dobeš became the third goaltender in NHL history following Viktor Fasth and Martin Jones to amass four inaugural career wins while allowing four or fewer cumulative goals through the same number of appearances.
