"A Night In Sickbay" is the thirty-first episode of the American science fiction television series Star Trek: Enterprise, the fifth episode of season two. It first aired on October 16, 2002 on the UPN within the United States. The episode was written by executive producers Brannon Braga and Rick Berman, and directed by David Straiton. Set in the 22nd century, the series follows the adventures of the first Starfleet starship Enterprise, registration NX-01. In this episode, after visiting the planet Kreetassa, Captain Archer's (Scott Bakula) dog Porthos falls ill with an unknown pathogen. Archer stays overnight in sickbay to look after his dog with Doctor Phlox (John Billingsley) knowing that afterwards he must take part in an elaborate apology display to the Kreetassans. The episode featured Vaughn Armstrong, who reprised his role of the Kreetassan Captain from the episode "Vox Sola". Several scenes also proved challenging for the main dog actor who portrayed Porthos, who was named Breezy. She was required to lie still for long periods, jump into Bakula's arms on command and also act on her own while her trainer was not on set. Berman compared the relationship between Archer and Phlox to The Odd Couple, saying that the episode was "a lot of fun". The episode was nominated for the 2003 Hugo Award for Best Dramatic Presentation (short form) and received the highest Nielsen ratings for any episode of Enterprise during season two at that point. Critical reception at the time was mixed, and in retrospect reviews were more negative. Plot After a five-day away mission spent apologising on the planet Kreetassa, the away team consisting of Captain Archer, Sub-Commander T'Pol, Ensign Sato, and Archer's dog, Porthos, return to the ship to decontaminate. Porthos has acquired a pathogen on the planet surface and must be quarantined. Archer learns from Commander Tucker of the ship's need for an extra plasma injector from the Kreetassans, but negotiations break down after it is discovered that Porthos had urinated on a sacred tree, insulting the Kreetassans. Archer reacts poorly to the news and is given a list of requirements he must meet in order to apologise. He and Doctor Phlox then tend to Porthos, and Archer spends the night in Sickbay to be with his pet. Throughout the night, as Porthos' immune system weakens, Archer experiences Phlox's side of life in Sickbay. During the night, as he dreams of Porthos' funeral,
