Welcome to LouCastle.com, the website that will help you learn to use an Ecollar.
This site is devoted to dog training. Primarily it's about using the Ecollar, but any methods are open for discussion from clickers to Ecollars and anything in between. There are "how-to" articles here that will teach you how to use an Ecollar to train your dog. There are general training articles to help you with common problems that occur with dogs. There's a forum to discuss questions that you have about how your training is going and to discuss problems that arise. There are places to display photos of your dog. The Forum is a place to discuss anything related to dogs or dog training.
There are many ways to use an Ecollar, but this site is concerned mainly with "softer" uses of them at low levels of "stim" to teach, train and proof dogs. If you already use Ecollars you can learn new techniques and improve your work. The methods described in the articles have been refined through years of using them on dogs of dozens of breeds, of all ages, and for dozens of issues.
This is NOT the correct place to have "the Ecollar debate" where people who oppose the tool rant about how "abusive" anyone is who uses the tool. If that's what you're interested in, go somewhere else.
