No, you cannot use your dog's current collar with the Fi Tracking Module, as there is no way to attach the Fi Module to your dog’s existing collar. An additional collar or harness can be used in tandem for pullers or dogs who require a specific set up for walks.
To use Fi, you must use a Fi Collar Band or a band from our Fi Makers program. Fi Makers are independent makers who provide a wide range of collar styles and tested for quality and strength. You can view all of our Makers and their different Fi compatible options here.
