"Congress president Sonia Gandhi has approved Dogra's candidature for the Dasuya by-election," Punjab Pradesh Congress Committee chief Capt Amarinder said.
Dogra is the son of former state minister Ramesh Chander Dogra, who had represented Dasuya constituency a number of times.
The bypoll was necessitated due to the recent death of BJM MLA Amarjit Singh Sahi.
