While still contracted until the end of the 2024 season, Harmes has spoken on his desire to seek a fresh start this off-season after failing to see any action during the Demons' straight-sets exit in September.
Previous reports have linked the hybrid mid-forward with a move to either Carlton, Essendon, Richmond or Sydney, but as stated by AFL Media's Callum Twomey on Saturday, the Dogs are also said to have entered the race for Harmes.
Though a shift across the Westgate could well eventuate, with Twomey claiming the Luke Beveridge-led side is keen on adding midfielder depth, Harmes' relationship forged with new Tigers coach Adem Yze could also prove to be a factor across the next fortnight.
However, the Bulldogs and Demons have a recent history of completing fair deals at the trade table, with ex-Dogs Josh Schache and Lachie Hunter making their way from the Kennel to Gosch's Paddock late in the 2022 exchange period.
The Bombers cannot be discounted either after list manager Adrian Dodoro and his team expressed an interest in bringing Harmes to The Hangar last off-season.
Since making his AFL debut in Round 15 of the 2015 season, Harmes has added a further 151 appearances in a red and blue guernsey, however, the 28-year-old has not featured at senior level since Melbourne's Round 21 win over the Kangaroos.
At present, the Bulldogs are currently armed with picks 10, 17, 37, 66, 69 and 72 at the 2023 AFL Draft in order to broker a deal.
