That had to hurt.

Watch as a woman on TikTok tests the strength of a shock collar she just bought for her dog.

She starts with the lowest possible setting, but when that doesn't seem to be very effective, she cranks it up and that's when she learns how strong these collars can be.

The young lady in the video below shocks herself and she falls to the floor, almost knocking herself out.

She says to not try this, and after seeing what happened to her here I think we'll heed the warning.

What I'd like to know now is after experiencing this, does she put the collar on her pet, knowing how painful the shock can be.

Now, one video blogger did some editing, and here's his take on this bizarre video. And yes, others have tried this in the past and when the shock collar was cranked up to a higher strength we got the same result.

Enjoy.
