I've been following the Smartwork program and know that Evan uses a TT e-collar. I have a Dogtra 1900NCP that I have been using and have a question. The way I CC'ed to Here was I started by 10 and worked my up in increments of 10, then by 5. I initially got a single response from my pup around level 35 and she'd come the rest of the way without any noise or discomfort it seemed. I worked my way up to 65 (out of 127) on continuous and she yelped a few times, but still didn't have the attitude of the dog in Evan's video. What level do those of you with the Dogtra units typically find as the max for your pups?
