This is my first time ever using a e-collar. I purchased the tri-tronics flyway g3 ext and my lab is 6.5 months is it to early to start? I tried cc today but she didn't like it at all I tried the lowest and different intensity like the DVD says that you are given. But my e-collar don't have the continue stimulation at low high and medium stimulations it just has high or low medium and high momentary stimulation. I have fowl dawgs series and Evan Graham's smart work program. Any advice? She knows what basic commands are such as sit, here, kennel, and heel and down but they are not instant response yet. Is e-collar recommended or should I just train her like I been doin with check. Ord choker collar and heeling stick?
