Using the trending Twitter hashtag “#dogsatpollingstations,” voters were showing up to the polls Thursday with their best pals posting photographic evidence of the experience on social media.

“Forget politics, this is the main reason to log onto Twitter today,” one Twitter user joked. “Delighted to announce there were dogs at my polling station this morning,” another tweeted.

Prime Minister Boris Johnson, of the Conservative Party, joined in on the fun when he brought his dog, a Jack Russell cross named Dilyn, to vote with him in London.

Sadiq Khan, the Labour Party’s mayor of London, also brought his pooch named Luna to the polls and posted a video online encouraging people to vote.

Some dogs went to the polls dressed up — in fun costumes from a bumblebee to Santa Claus — while other dogs’ owners announced who they were voting for online.

It was not immediately clear how many dogs actually got inside voting booths. According to the electoral commission’s rules, animals, “apart from assistance dogs, are not usually allowed inside polling stations so will need to be secured outside if you do decide to take them with you.”

It is hoped Thursday’s election, which is being held more than two years ahead of schedule, will break Britain’s political impasse over Brexit and determine its future relationship with the European Union. Additionally, all 650 seats in the House of Commons seats are up for grabs.

The House of Commons consented the legislation by a wide margin of 438 votes to 20. Making the first December election since 1923 possible.

However, the bill yet to be approved by the Lords could become law before the week runs out.

There will be a five-week campaign up to polling day if that goes into effect.

The PM, Boris Johnson believes that the citizens of Britain must be “given a choice” over Brexit’s future and the country as a whole.

The Brexit deal and Parliamentary deadlock have been the cause of the UK’s exit being further extended to 31^st January. Nonetheless, Boris Johnson hopes that the election will give him a fresh mandate.

“It is time to come together to get Brexit done,” The PM said as he exited a meeting of the 1922 Committee of backbench Conservatives held shortly after the vote.
