Before getting the SportDog collar, I didnt feel as though I was fully in control of my black Lab X. He was pretty touch and go with smaller dog and animals. Now I have full control on correcting that bad behavior and I feel at ease going to the dog park and walks. An E-Collar is an amazing tool if used correctly and I'm thankful for it. I purchased the SportDog collar at the suggestion of the Dogline consultant on the phone, and they were amazingly helpful and hospitable. They had my order sent that day and I was able to get started on training my dog almost immediately. The DogLine. 10/10. Would shop again.
