There will be a new addition walking the corridors of power on Downing Street, the site of the British prime minister’s official residence – one with a tail.

Prime Minister Boris Johnson and his girlfriend Carrie Symonds welcomed a rescued Jack Russell puppy into their home Monday, which Symonds dubbed ‘Dilyn’ on her

Dilyn was rescued from a Welsh puppy farm, and charity Friends of Animals Wales said in a statement on their that they were “overjoyed†that the puppy had been given a home where he “will be living his best life.â€

Tongue-in-cheek rumours abounded on social media about what the other furry resident of Downing Street – chief mouser, Larry the cat – would feel about the new resident.
