The man, 21, who cannot be named, had been in a relationship with the 19-year-old about seven months when they argued before going separately to Brisbane's Fortitude Valley in March 2022.
He was kicked out of a club for disorderly behaviour and got into a fight before the couple travelled home together.
The then 20-year-old got annoyed when his partner said a man had asked if she was single while dancing with her.
At home he locked her outside, saying he was going to treat her like a dog, Brisbane District Court Judge Amanda McDonnell said in sentencing the man on Thursday.
The teenager was woken by the man pouring water over her and tipping the chair she was sleeping on.
He grabbed her arms, throwing her on a table before pushing her into dog faeces.
During an argument inside, the man grabbed her throat so she could not breathe, swallow or speak.
He was arrested for breaching a protection order after neighbours called police.
The court heard the man used drugs and alcohol to cope with emotional challenges at the time.
The 19-year-old was the second partner he had been violent towards.
"That's not how we treat people whom we love and who trust us," Judge McDonnell said.
"I really ask that you reflect upon your conduct and look to turning your life around."
The 21-year-old was given a head sentence of three years behind bars after pleading guilty to strangling and assaulting his then partner, smashing her car window and stealing her phone.
He also tried to contact her in contravention of domestic violence orders while remanded on the charges.
The man also admitted being part of a group that robbed a man in Fortitude Valley in December 2021.
He was released on parole on Thursday after serving more than 16 months behind bars.
