CARRIE Symonds was pictured happily snuggling her new puppy Dilyn today after he was delivered to Downing Street this morning.
The 15-week-old pooch, adopted by Carrie and Boris Johnson, arrived at the new Prime Minister's home, after being saved from dog traders.
The Jack Russell-cross pup - which faced near-certain death after being abandoned by a Welsh farmer - moved into No10 today.
Downing Street's current furry resident, territorial Larry the cat, is due for a surprise, as his position as "top dog" could be rivalled by the new arrival.
Carrie tweeted today: "Thanks to the wonderful Eileen from @FOAWales who rescued Dilyn after she got a tip off that he was to be dumped by a puppy dealer because he was born with a crooked jaw.
"Eileen fixed his little jaw & saved his life. She is a hero."
It comes as Boris faces the biggest test of his career this week, as MPs return from their summer break tomorrow.
Labour will team up with Lib Dems and up to 17 Tory rebels, including ex-Cabinet big guns Philip Hammond and David Gauke, to take control of Parliament as the Brexit battle continues.
But the PM has vowed to fight them with everything he's got, and is planning a range of secret tactics to try and stop them. If he fails, he is poised to call an election for after October 31, and could take Britain out without a deal.
Amid such a busy week, the arrival of a playful puppy may well provide some much-needed light relief for the PM.
Why have they chosen Dilyn as a name?
Boris Johnson and Carrie Symonds chose to name their new pup Dilyn in a likely nod to where he was saved.
The 15-week-old Jack Russell-cross was found before a puppy dealer was about to dump him in Wales - as he was born with a crooked jaw.
The word Dilyn in Welsh means to follow or succeed.
This could be a reference to the young pup's rags to riches story, or a show of Boris' confidence in his role as Prime Minister...
Unlike Larry the No10 cat, the dog will belong to Boris and Ms Symonds rather than whoever occupies Downing Street.
And he will be trained to get along with chief mouser Larry - who is famously territorial.
Staff have offered to take the pup on walks after voting overwhelmingly in favour of getting a dog when polled by the PM.
It comes as Boris and Ms Symonds hope to raise awareness for strict new anti-puppy farming legislation.
Known as Lucy's Law, the clampdown will come into force next April and targets third- party puppy sellers who breed dogs often in brutal conditions.
Lucy's Law is named after tragic pet Lucy - a Cavalier King Charles Spaniel who died of her injuries just three years after being rescued from a terrible puppy farm.
The new legislation - backed by celebs Ricky Gervais, Rachel Riley and Brian May - will make it illegal for a puppy or kitten to be sold without seeing it interacting with its mother in the place where it was born.

PupAid founder Marc Abraham, who helped spearhead the legislation, said last night: "I’m absolutely delighted that the Prime Minister and Carrie have chosen to rescue a puppy, which will hugely help to highlight Lucy’s Law.’
He added: "Eileen is an absolute hero who has racked up massive vets’ bills picking up these poorly puppies and breeding dogs.
"I hope this encourages others to adopt and donate to her work."
