Ultimate Fighting Championship
Dober stepped in for an injured Sérgio Moraes to face Sean Spencer at The Ultimate Fighter 18 Finale on November 30, 2013. He lost the fight via unanimous decision.

Dober faced Leandro Silva on March 21, 2015 at UFC Fight Night 62. Dober lost the fight via technical submission in the second round. Silva was attempting to secure a guillotine choke after dropping to the mat with Dober's neck secured in his arm. Dober defended and moved his body to the side to stave off being caught in the choke. Silva appeared to be losing his grip on the submission as Dober continued to work free. However, the referee stepped in and touched the fighters as if to motion that he was standing them up. In reality, he was stopping the fight due to submission despite the fact that Dober never tapped and was in no significant danger of being choked out from the hold. Despite the loss, UFC awarded Dober his win money with president Dana White stating that he would have liked to see the result overturned and the match declared a no contest. The fight was later overturned to a "No Contest" by the Brazilian MMA Athletic Commission (CABMMA) after the referee Eduardo Herdy admitted his mistake.
Dober then faced Efraín Escudero at UFC 188 on June 13, 2015. He lost the fight by guillotine choke submission in the first round.

Dober was expected to face Islam Makhachev on April 16, 2016 at UFC on Fox 19. After the weigh ins, the UFC announced that Makhachev had failed an out-of-competition drug screening, testing positive for the banned anti-ischemic meldonium. The match was cancelled.
