Is My Replacement Band the Correct Size?

Ordered the wrong size collar kit? Growing puppy? Fi Bands are interchangeable, but limited to their series. You can purchase additional spare bands as needed for the Fi Collar Series needed.

Concerned you received the wrong size? The Fi Band is measured differently than a fully assembled collar. You will need to measure your band with the module removed.

Steps to Confirm the Correct Size

1. Shorten the spare Fi Band to its shortest setting.

2. If your band still has a Fi Module attached, see: Replacing The Fi Collar Band, for instructions on how to remove the module.

3. Lay the collar flat and measure the length without the module, end link to end link. 
   

4. Compare the measurements to our size guide shown below. The spare band lengths (when adjusted to the smallest size) should be as follows:

     • The buckle for sizes Extra Small - Medium is plastic, where the buckle for Large & Extra Large is metal.

       • Small: 9"
       • Medium: 10.7"
       • Large: 13.4"
