Had a strange happening. Noticed one of my dogs (that is softer) really vocalized on a blind when I nicked him on a 1 setting for whistle refusal. Didn't think much then noticed my other dog that is HIGH energy and not soft completely bugged out when she got a correction at a level of 1 for refusing to enter cover---so much so that it created an area that was hot that she would not enter--not like her at all. Each has their own collar. I've tested the collar in palm of my hand before on a 1, 2, and a 3. The 1 was barely noticed, 2 was a buzz and 3 I really felt. Today I put each dogs collar against my leg on top of my shorts and a 1 was VERY sharp and I wouldn't even try a 2 or 3. Also tried on the V setting in my hand and I swear it vibrated AND nicked me enough to cause the collar to fly out of my hand. These collars have been used for two weeks (3-4 days/week) since they were charged last.
Anyone with similar issues? Anyway to test other than on myself -- did have another person in training group test the collars on a 1 setting and she was shocked (pun intended) at the level of output. Collar clinic was only other suggestion i got.
