Dogs/The Gunmen mystery

The Dogs episode "The Gunmen" has become slightly infamous online due to the episode never airing. Various people have looked for the episode.

The episode
The Gunmen was the seventh episode of the series' first season. It revolved around the pound going on lockdown due to two gunmen entering the building.

The mystery
The episode was set to have its UK premiere on August 5, 2015 on BaconNetwork at 4:15pm, the usual timeslot for new episodes at the time. One fan claims that he saw the episode's title and its synopsis on the TV schedule on July 29 in its regular timeslot on August 5, before it was changed to a rerun of The Escape Plan on August 1. This was later backed up by a photo of the episode's timeslot. Viewers tuned in in case it was a mistake, however The Escape Plan did indeed air. Fans then noticed the other episodes released at the time were having reruns throughout the following weeks, but The Gunmen was nowhere to be found. The episode was listed on the Dogs episode list on BaconNetwork on July 29, but was deleted on July 31. A fan, after watching all season one episode excluding The Gunmen, noticed two scenes in the commercial for new episodes airing at the time on August 14. The two scenes were Rebecca screaming and an alarm ringing. Another commercial with all the same footage of the previous one aired starting August 15. promoting reruns of the then-new series, but these two scenes were cut from the commercial. These two scenes are likely from The Gunmen and was the only footage of the episode for a long time.

On February 5, 2016, the episode and its synopsis appeared again in the schedule to air on February 12 at 8:45pm. This quickly spread around the internet and was the highest-rated program of the week, but unfortunately was a rerun of season 2's The Biscuits.

On March 18, 2016, a four second clip of the series where two men walked past a table where Quaxalia was hiding was uploaded to YouTube, and is the longest footage of the episode in English. However on December 22, 2016, 2 minutes of the episode was uploaded to YouTube in Dutch. The video currently has over 100,000 views. Another user roughly translated the lines and redubbed them him/herself before uploading it in English. The user who uploaded the Dutch version then commented on the Dutch video "I'd like to clear some things up. The episode was indeed aired in the Netherlands. It premiered in January 2016 but never reran. I'm an eager fan of the series so I recorded a clip to send to my friend who didn't have Nicktoons. When I heard about all the fuss about the episode, I decided to upload my footage. Unfortunately that's all the footage I have. Thanks for 50,000 views!"

No other footage has been found since then.
