Lola is 8 months old and ~55lbs.
I decided to give an e-collar a try after seeing some positive reviews and some videos from solidk9training.
I got it today and started doing some recall stuff. I wanted to find Lola's "working level" or "baseline". I put the collar on the absolute lowest level and gave her a split second of stimulation expecting nothing. She yelped and cried worse than I've ever seen as if I'd slammed her paw in a car door. In fact, her tail got hit by the car door once and she didn't cry this bad. I feel absolutely awful about it, but I'm wondering if maybe I just got a bad collar or something. I can't believe the level 1 hurt so badly.
