Educator Collars (also known as E-Collar Technologies) is an e-collar manufacturer for dogs. They make remote e-collars, no-bark collars, and pet containment supplies (like shock collars and invisible fences). Everything is built in the US, but they have to source some materials from overseas, unfortunately. All of their products are thoroughly tested and pass every quality control standard before they reach the shelves. Educator Collars has a lot of advanced features and different models, so make sure to scan each one to find out which will be best for your dog.
