What size collar should I get and how do I use it?
As a dog trainer, I love teaching people how to properly use training tools! However, I likely don't know you or your dog, so I suggest contacting an experienced trainer local to you for proper fit and instruction on any type of training collar. See the Find a Trainer page to see a list of trainers I know around the US and Canada that are experienced with my buckles and the proper use of prong collars. If you don't see anyone on the list near you or need additional help, feel free to reach out and I will help however I can.
