The Ferrari driver had been due to run Pirelli’s prototype tyres at Italy’s Mugello circuit on Friday, but his place will instead be taken by reserve driver Zhou Guanyu.
Hamilton explained to fans that Roscoe, 12, had been diagnosed with pneumonia and placed under sedation for further checks when his heart suddenly stopped.
In a coma
Writing on Instagram alongside sharing photos from Roscoe’s bedside, the seven-time world champion revealed: “They managed to get a heartbeat back and now he’s in a coma. We don’t know whether he will wake from this. Tomorrow we’ll try to wake him up. I’m by his side and want to thank you all for your prayers and support.”
Formula 1 canine star
Roscoe, who has become something of a Formula 1 celebrity in his own right, boasts more than 1.3 million followers on Instagram, where he is described as “a vegan bulldog that loves to travel and play ball”.
The dog has frequently accompanied Hamilton to races and media appearances, becoming a familiar figure to fans worldwide.
Fans everywhere will be hoping Roscoe makes a full recovery and is soon back home by Hamilton’s side.
