The Western Bulldogs were $12 to win the AFL Grand Final early in the finals series but TAB has already seen some interest in them to defeat Melbourne on Saturday week.

TAB first posted the Bulldogs, who started the season a $13 premiership chance, at $2.30 in head-to-head betting but they are now $2.25. Melbourne, who went up $1.60 after its win over Geelong, is now $1.65. The $1.90 line has been set at 7.5 points.

The Demons started the season a $26 chance and were responsible for some healthy bets at big prices, including one bet of $1000 at $26, two bets of $1000 at $21 and a $3000 bet at $17.

Marcus Bontempelli is the shortest-priced Bulldog in Norm Smith Medal betting, at $8, with Jackson Macrae $9. Christian Petracca and Clayton Oliver are the joint $6 favourites.
