Meechan received press coverage when he posted a video showing him teaching his girlfriend's dog how to raise its paw in the manner of a Nazi salute, and to react to the phrase "Do you wanna gas the Jews?" Meechan was arrested and convicted of being "grossly offensive" under the Communications Act 2003, following a trial in March 2018. The arrest generated controversy and discussions about free speech. In April 2018, Meechan was fined £800. Meechan stated he would not pay the fine, and instead donated £800 to the Glasgow Children's Hospital Charity. In March 2019, the money was seized from his bank account by an arrestment order.
In April 2016, Meechan posted a video on YouTube of his girlfriend's pet pug Buddha titled "M8 Yer Dugs A Nazi". At the start of the video, he says: "My girlfriend is always ranting and raving about how cute and adorable her wee dog is so I thought I would turn him into the least cute thing I could think of, which is a Nazi." In the video, the dog, prompted by the command "Sieg Heil", raises his right paw in the manner of a Nazi salute, watches a speech by Adolf Hitler (were the footage shown from the Triumph of the Will), and responds immediately when Meechan asks if he wants to "gas the Jews". It ends with images of Hitler and Buddha depicted with a toothbrush moustache similar to Hitler's.[better source needed]
Meechan was arrested on suspicion of breaching the Communications Act 2003. On 19 March 2018, Meechan was convicted of breaching the act by Sheriff Derek O'Carroll at AirdrieSheriff Court. The court ruled that Meechan's claim that the video was a joke intended for his girlfriend "lacked credibility" as Meechan's girlfriend did not subscribe to the YouTube channel to which the video was posted. On 23 April 2018, Meechan was sentenced to a fine of £800, with no prison sentence.
Sitcom writer Graham Linehan condemned Meechan. Meechan responded by saying that Linehan's show Father Ted also contained Nazi-related jokes. Meechan was scrutinised for embracing support from right-wing figures Alex Jones and Tommy Robinson, to which he replied: "Imagine totally abandoning protecting human rights, just because someone you don't like is defending them too. Astounding." On 6 May 2018, Meechan spoke at the "Day for Freedom" rally, organised by Robinson, which was described as far-right by news media and observers.
Sheriff O'Carroll noted that there were only "very limited" submissions from the defence and the prosecution on the matter of the law as it regards freedom of expression; because of this, the trial was "concerned, ultimately, only with the narrow fact-based question of whether the Crown has proved beyond reasonable doubt that your using a public communications network on one day to post the video onto your video channel, constituted an offence contrary to section 127(1)(a) of the Communications Act 2003". He said the ruling sets no precedent.
Meechan started a GoFundMe campaign on 24 April 2018 to raise £100,000 for an appeal and reached his goal as of 25 April. In August 2018, Meechan announced that his request for an appeal had been denied by a member of the Sheriff Appeal Court, who also accused Meechan's lawyer of contempt. The letter stated that the appeal was "not arguable" due to the nature of the "deeply unpleasant offence". Meechan stated that he plans to contest the matter with the Scottish Criminal Cases Review Commission. Meechan's lawyer Dorothy Bain subsequently petitioned the High Court of Justiciary to hear the case. Senior judge Lord Carloway opined that the High Court did not have the power to grant an appeal denied by the Sheriff Court. In March 2019, the £800 was seized from Meechan's bank account under an arrestment order.
On 17 June 2020, Meechan announced that his additional appeal to the Supreme Court was also rejected. Meechan stated his intention to bring the case to the European Court of Human Rights.
BBC Scotland planned to feature Meechan in a 2019 debate program, The Collective, and had him film two episodes. However, the network announced that these episodes would not be aired after a backlash over the announcement.BBC Three produced a documentary on Meechan's case which aired during the summer.
