Boris Johnson's frisky dog has apparently been caught trying to have sex with the Chancellor's pooch on several occasions.
No. 10 sources reportedly said the Prime Minister's Jack Russell, Dilyn, jumps on Sajid Javid's cavapoo bitch Bailey whenever she enters the Downing Street garden.
Dilyn made a beeline for Bailey on one of his early morning walks, with the Tory leader being forced to drag him off the Chancellor's pet, it is claimed.
The two dogs have been seeing a lot of each other since Mr Johnson moved into No. 10 and Mr Javid took up residence in No. 11.
Dilyn is now whisked away whenever he and Bailey get near each other in the garden, The Sun reports.
The Prime Minister moved the pooch into Downing Street last month after adopting him with his girlfriend Carrie Symonds.
Dilyn has undergone training to help him get along with No. 10's cat, Larry.
Mr Johnson walks his dog around the No. 10 garden wearing just his boxer shorts, according to reports.
He adopted the pooch, which has a misaligned jaw, after the animal was abandoned by puppy farmers before being rescued by a charity in Rhondda, South Wales.
Friends of Animals Wales owner Eileen Jones described the pet's journey to Downing Street as a 'Cinderella' and 'rags to riches' story.
The Prime Minister told the Mail on Sunday: “The dog is in great shape.
“I get up at six o'clock in the morning and stagger around, walk around the garden with the dog.
"It's a keep-fit regime in my boxers.”
