✅ Verified Fi Maker ✅

We are proud to be a verified Fi Maker, meaning our collars have been tested and approved to meet Fi’s compatibility standards. We also use genuine Fi attachment clips to ensure a secure fit and reliable performance with your device.

Please note: we currently only offer 3/4" attachment clips. For 1" wide collars, the Fi attachment accent pieces will be 3/4" wide. For an example of this design, please reference the yellow and black collar shown in the product images.

Fi Compatibility Options

Choose the style that best fits your pup and Fi setup:

Layered Style

A bold layered look featuring up to two BioThane® colors for added style and dimension. The primary color is used to make the collar, with the accent color being placed on top. Your Fi device will sit on top of the primary color. 

Series 3+ Note: Fi recommends that the series 3+ device sits directly on the dog's neck for optimal functionality/tracking of additional behaviors. The in-line style is best for the 3+ edition.

In-Line Style

A sleek, streamlined design where the Fi unit sits directly in line with the collar. The primary color will be used for a majority of the collar, with the accent color being used to attach the clips, all in one line so that the device sits directly on the dogs neck.  
⭐ Recommended for Fi Series 3+ for the best overall functionality and fit.
