’s pet dog Dilyn may have caught the coronavirus as the deadly bug swept through Downing Street, it has been claimed.

The Jack Russell rescue dog is said to have been left subdued, wheezing and refusing to go out for walks during April when the Prime Minister was fighting for his life in hospital.

The 56-year-old former Mayor of London was put in intensive care at St Thomas’ Hospital with a cough and fever – though reports he had not been put on a ventilator were denied.

Fiancée Carrie Symonds and Health Secretary Matt Hancock were among those in the PM’s inner circle to contract the virus during the pandemic’s peak in the spring.

Ms Symonds, who was pregnant at the time, shared a selfie cosying up to Dilyn as she self-isolated at the south London home the couple share.

A source told The Sun : “It’s well known that the virus did the rounds through Downing Street, but it appears to have affected little Dilyn too.

“He wasn’t tested so we can’t be sure, but around the same time as Carrie came down with it he was very lethargic, tired and didn’t hop about as much.”

“Looking back, it’s pretty likely he had it. Fortunately, like the PM, he’s made a full recovery and is fit as a fiddle.”

While official government advice states there is no evidence Covid can pass between pets or be transmitted from them to their owners, dogs can catch the virus though only have mild symptoms.

Dilyn made headlines last December when Mr Johnson left his local polling station after voting in the General Election with him on a lead, before giving his pet a kiss.

Then in May, the PM was spotted on an early-morning run with the little dog amid a backlash over his refusal to sack adviser Dominic Cummings after he allegedly breached lockdown rules multiple times while displaying symptoms.
