Fi Compatible

Fi Dogs are adventure dogs! They go places, they roll in things, they get dirty…and they have a BLAST doing it. But who wants to smell all that gunk later? Ditch the nylon collar and get a Fi Compatible BioThane collar that stays stink-free, is easy to wash, and looks amazing.

1" Fi Collar

The 1″ collar is the same width as the Fi Links all the way around, choose from over 25 colors and 3 hardware options.


If you like to use your Fi collar with an Ecollar, let us know when checking out so that we can make the collar a bit longer to acomodate for the Ecollar module.

3/4" Fi Collar

The 3/4″ Fi collar has 1″ tabs that attach to the Fi Module, while the rest of the collar is only 3/4″ wide. The hardware is a little bit lighter and the width a little bit smaller making it a great option for our smaller Fi dogs.


If you use your Fi Collar with an Ecollar, let us know when ordering, we’ll make it a little bit longer to accommodate.
