The Western Bulldogs have confirmed Kieran Collins and Nathan Mullenger-McHugh both will not be offered contracts for next season.

Collins played just one senior match for the club in Round 9, 2016, after joining the Dogs via the 2015 AFL Draft.

Mullenger-McHugh has not played a senior game, and has been on the club's rookie list for the past two seasons.

Dogs' General Manager of List and Recruiting Sam Power thanked the pair for their work at the club during their time at Whitten Oval.

“We’d like to thank Kieran and Nathan for their hard work and commitment during their time at the Western Bulldogs, and we wish them all the best for the future,” Power told westernbulldogs.com.au.
