The 25-year-old, who was delisted by Freo last month, has joined the Bulldogs as a free agent.
Watch Nick Lower speak exclusively to BulldogsTV on the media player above about his signing with the club.
"I'm really over the moon. I couldn't be happier," he told westernbulldogs.com.au on Monday afternoon.
"I really was pretty unsure with what would happen in the future, but I couldn't be happier to have landed at the Western Bulldogs."
Lower played 20 games, mainly as a defender, for Port Adelaide from 2006-09 and made 22 appearances for Fremantle in 2011 and 2012.
He enjoyed a stellar season in 2011, playing 19 games in the midfield and ranking second at Freo for tackles and fourth for contested possessions.
But fitness and form issues restricted his output this year.
Lower didn't play his first AFL game until round 13, although he did make an impressive return by gathering 30 possessions against Essendon.
He lined up against Collingwood the week after and picked up 20 touches, then racked up another 21 disposals and a goal in Freo's easy win over the Bulldogs in round 15.
However, he missed Fremantle's round 16 match against Melbourne and was unable to break back into the team during the closing stages of the season.
After being axed by Freo he accepted an invitation to train with the Bulldogs and started his time at the club last week.
"Second chances don't come around often and third chances are even a slimmer chance," Lower said.
"It's been a bit of a difficult period after getting delisted over the last couple of weeks … but I'm really excited.
"There's a great group of young talent here, as well as some top-echelon players among the old boys, so I'm just looking forward to getting amongst them and getting to know the boys a bit better."
