The seven-time world champion missed a Pirelli tyre test in Italy as well as an event at Milan Fashion Week last week after the 12-year-old dog caught pneumonia and was placed in a coma.
He said Roscoe was put to sleep on Sunday, in his arms.
"After four days on life support, fighting with every bit of strength he had, I had to make the hardest decision of my life and say goodbye to Roscoe," Hamilton told his 40.9 million followers on Instagram, where the bulldog had a following of 1.4 million.
"Bringing Roscoe into my life was the best decision I ever made, and I will forever cherish the memories we created together."
The pet accompanied his vegan owner through six title seasons with Mercedes – attending races with his own paddock pass and travelling by private jet. Hamilton's other dog Coco died in 2020.
Hamilton races in Singapore this week, still chasing a first podium with Ferrari since joining the Italian team in January.
Rest in Peace Roscoe Hamilton, a true star in his own right ✨
