Makes boundary training easier
April 25, 2026
After having trouble training to boundary with the SDF-100C, I switched to the SDF-CTR. That meant I needed to buy a complete contain & train system since SportDog chose to make the 100C and CTR incompatible (not noted on SportDog's website). Training went much better when I got to the phase where I walked behind the dog, first on a check cord and later without one. I was able to make sure the dog was getting a tone or a vibrate by using the controller. Training was quick, and for a couple days, I sat on the deck with the controller to reinforce any straying.
