At this time, there is no official way to attach the Fi module to your dog’s existing collar.
We were sure to source the best quality materials and hardware for the Fi collar band in terms of durability, comfort, safety, sleekness, and functionality. The Fi collar band is weather resistant and soft on your dog’s fur. Most importantly, you don’t need to remove the Fi module from the collar to charge it.
Using your dog’s current collar with Fi is a feature that we are currently exploring, and we’d love to hear from you about what you’re looking for. Please send us some info on the collar you’re hoping to use with Fi via our request form and we’d be happy to see what options we have to help you.
