**WARNING: DISTRESSING CONTENT BELOW**
The woman – who hasn’t been identified – aired the distressing act on Instagram over the weekend from her house in Dallas, Texas, US.
In the clip, she says: “Okay, I’m going to do it. I’m going to put his ass back in the dryer.
“He liked that s**t.”
She encourages the small white pooch to walk closer towards her where she picks him up.
As the woman places him inside of the dryer he appears to go rigid from fright.
She then screams at the dog before shutting the dryer door behind him.
The woman goes on to clap, cackle and scream with laughter as the helpless animal’s body bangs against the spinning metal drum.
While letting out another screaming laugh she opens the door where the dog instantly jumps out and ran away.
The woman continues to laugh as she turns the camera back on her pooch cowering underneath a table the other side of the room.
Despite the dog appearing obviously frightened, the woman doesn’t stop laughing as she offers an offhanded apology.
Viewers who tuned in to the live stream were commenting throughout.
One person appeared to encourage her, adding: “Do it.”
Others shared laughing face emojis.
While a third said: “Ooh girl, you’re going to kill that b***h.”
A Twitter user who happened to come across the disturbing footage re-shared it online and begged the public to report the unknown woman.
She said: “Someone please call the police on this girl, Some people don’t deserve dogs or pets at all. It’s complete abuse how they treat them.”
A second said: “I’m sick to my stomach after watching that. That person should be arrested for animal abuse. Please find out who she is.”
The woman’s Instagram account has since been deleted.
