The freshly inked agreement will see Poulter call the Kennel home through to the end of 2025.
Poulter saw his time at Collingwood come to a close at the cessation of the 2022 season, delisted after just 12 appearances in black and white.
However, after a promising start to his time with Footscray's VFL outfit, Poulter earned a call-up to Luke Beveridge's senior side by way of the 10th pick of the mid-season draft.
The South Australian's dash between the arcs has seen him push from the fringes of selection to make a further nine AFL appearances before the Bulldogs' season came to a close ahead of September.
Dogs list boss Sam Power paid praise to the mulleted winger, stating that Poulter had delivered on his promise to make those around him respect his performances.
“Poults came to us during the mid-season draft in May and hasn't put a step wrong since returning to the AFL ranks here at the Club,” Power told Bulldogs Media.
“His outside run has given us a different look on the wing, with his attributes on full display on the weekend with 27 touches and three goals in the Elimination Final victory over Casey.”
“Being only 20 years of age, we're excited about the growth of Poults as he gets more consistent AFL football under his belt over the next two seasons.”
Since making his AFL debut in Round 7 of the 2021 season, Poulter has played a total of 21 games and slotted five goals, three of which came this season.
