A Toronto dog owner has posted a disturbing video of her pet Rottweiler hanging by its collar to Facebook, in a bid to warn others of the potential danger when taking leashed pets on elevators.

On March 2, Ryerson University student Tamara Seibert was taking the elevator to the ground floor of her building when one of her dogs' leashes got caught in the door.

As the elevator began to descend, she noticed her Rottweiler's dragging leash was stuck, so she started to pull on it. The dog, named Vlado, was almost immediately hoisted into the air by his collar.

Seibert frantically clawed at his collar and pushed the elevator buttons, trying to open the doors as her dog hung in the air. The dog struggled, pawing at the door as his owner ripped at his metal collar, trying to get it off.

"I just wanted to get him down," Seibert told CTV Toronto.

After the dog had hanging for approximately 30 seconds, the elevator doors opened and the dog fell to the floor. The two dogs then ran out of the elevator as Seibert held the doors open with her feet, cradling one hand in the other.

The skin on her hands was torn open by the dog's metal collar, she wrote on Facebook of what she called one of the "most traumatic experiences of my life."

When she found out a closed-circuit video camera recorded the entire incident, Seibert requested a copy of the tape, and posted it to her Facebook page as a warning to others.

"I am posting this because thank god my dog survived but I want to warn people how fast something so simple can go horribly wrong (sic)," she wrote.

"I never want anyone else to ever go through this."
