As far as I know, Sirius is a binary star system with no known planets, so unless there are planets lurking in the system that we don't know about then the answer is no.
It's wiki page says that there was a study done on it in 2008 which looked for a third star or planet, and it came up empty. Sirius is only 8ly away, so we probably would have detecting it then.
The Sirius system is also very young (only 200 million years) and has already been through the death of one of it's two stars which probably doesn't help the prospects of life.
