I have been using the eCollar since 2014 — its never been my go to tool nor my favorite thing to teach owners. However I am certainly using it now in terms of precision and accuracy, as well as a foundation for clear and rewarding communication between the dog and handler. Before Robins advanced class it was more of an add on by request or whomever I am working for wanted it done — I will never think every dog needs an eCollar but as I grow and expand as I have in this class –I will say that this tool, when used correctly and kindly, is the best tool in dog training to give the dog and human the ultimate in freedom, joy and relationship while being responsible in typical society… Robins course and her teachings in general really opened that up for me — and I think any professional would benefit from taking this class!
