It already has. Sirius B is a white dwarf, the dense remnant of a dead star. While it is no longer producing energy through fusion, Sirius B still glows with the leftover heat of when it was an active star. Because of the huge amount of heat and relatively small surface area, it will take trillions of years for Sirius B to cool.

What is the life and death of Sirius the star?

Sirius's fate might be peaceful; just ejecting it's outer red giant layers to make a planetary nebula. It is 2.02 times the mass of the Sun. However, Sirius has a white dwarf companion. On Sirius B's death, Sirius A might have formed. At the other end, Sirius B might destroy Sirius A. White dwarfs have very strong gravity, and if it is close enough, Sirius B might steal material from Sirius A. When a white dwarf stealing mass from the parent star has enough mass to create iron, the iron triggers a Type 1a supernova. If this happens to Sirius B, Sirius A could either be destroyed by the immense force of the explosion, or become a runaway star, travelling faster than even Barnard's Star. If this is the case, Sirius A might eat smaller stars or crash and burn into a larger star. If it heads towards us if this happens, we would be doomed.
