The Eagles have given up a 13-point lead halfway through the last term to be defeated by the Dogs to the tune of seven points.
In a classic contest at Marvel Stadium it was the Dogs skipper Marcus Bontempbelli converting in the last 30-seconds of the match to give the home side a 14.16.100 to 14.9.93 win.
Josh Kennedy booted four goals, Jack Darling three and Liam Ryan, Jermaine Jones, Oscar Allen kicked two each.
Eagles coach Adam Simpson thought post-match the game was a bit of a rollercoaster ride.
"We got jumped early. But we defended well.” Simpson said.
He also confirmed his side came away reasonably unscathed from the clash.
“Nic got a knock in the eye, just a scratch, and Oscar hit his shoulder, otherwise we came out of that healthy."
