How To Use The Fi GPS Dog Collar With Other Collar Brands in 5 Steps

All opinions are our own and never influenced by brands. If you buy through links on this page, we may earn a small commission. Here's our process.

Our adventure dog Kepler wears his Fi GPS collar every day – we love that it tracks his location and steps, and provides us with a way of locating him in an emergency, if he was to get lost.

While the Fi GPS unit comes with a purpose-designed collar that connects to the matchbox-sized unit, I wanted to work out how to use the Fi GPS Dog Collar with other collar brands, so he can wear different styles and colors – such as his gorgeous Bend-inspired Ruffwear Crag collar, without having to be concerned whether or not the brand makes collars specifically designed to be Fi-compatible.

After giving it some thought, I found an easy way to use the Fi Dog GPS dog collar unit with pretty much any other brand of dog collar – in this case, the aforementioned Ruffwear collar.

The best thing about this way of getting the Fi Dog GPS on another brand’s collar is that it takes a few minutes, costs NOTHING (assuming you have the Fi and a collar to use) and requires no special skills, or even any sewing.

By the way… if you’re wondering what the Fi dog collar is all about and why Kepler wears one, you can learn more about it and see more photos in our Fi GPS dog collar review.


How To Use The Fi GPS Dog Collar With Other Collar Brands in 5 East Steps

Step 1: Remove the Fi GPS unit from its existing collar

The Fi Dog GPS unit comes with a 1 inch webbing collar, which is specifically designed so that the webbing either side of the unit is sewn around its two metal C-shaped rings.

To switch between different Fi-specific webbing collars, swing the ring up above the GPS unit, and carefully push down until the metal C-ring comes out of its attachment hole on the Fi device.

How exactly do you remove the Fi GPS Dog Collar’s metal clips?

We’ve been asked this question a lot, and it’s most easily explained in a video:

Step 2: remove the two C-shaped metal attachment rings from the collar

If you are not precious about keeping or re-using the existing Fi collar again, perhaps because, like us, you have more than one of them, then the easiest way to remove the metal rings is by cutting the webbing on the collar.

This obviously means you can no longer use the collar, which is a shame.

Alternatively, it should also be possible to push the metal ring out of the webbing, so you don’t damage it and have the option of returning the C-ring to the original collar in the future.

Step 3: Ready your new dog collar for the Fi GPS unit

The easiest way to ensure the Fi GPS unit will fit on your new dog collar is to use a collar that closely resembles the Fi collar, in terms of width and material.

Our Ruffwear Crag collar is the same width as the Fi GPS collar – 1 inch – and is also made from webbing.

It may be possible to use other materials of dog collar, however as some, such as leather and biothane, tend to be thicker than webbing, the next step may be pretty tricky if you use one of those materials, because you’ll need enough space to fold the collar onto itself and still be able to fit the C-ring attachment onto the Fi GPS unit.

Step 4: Attach the Fi GPS to your dog’s collar

Locate the area on the collar where you want the Fi GPS unit to be sitting.

I placed Kepler’s Fi unit on the doubled-up area of his Ruffwear collar, making sure the writing is the same way up as the Ruffwear branding.

There is plenty of space for the unit to sit flush against the webbing, and as it is doubled-up, the fit is a bit more snug and secure than sitting on a single layer of webbing.

Locate the C-ring under the webbing, with the attachment points facing up.

Then bend the webbing over the top of the Fi, so that the C-ring attachments are pointing down towards the Fi GPS unit.

This puts it in the best angle for re-attaching. Then bring the C-ring down below the Fi, and pull up to slot the attachment points into the unit.

It’s fiddly, but worth it!

Repeat for the other side of the Fi unit… and VOILA! A Fi GPS x Ruffwear dog collar is yours!

Optional Step 5: Reduce movement of the unit around the collar

The fit against the webbing isn’t overly snug, so the GPS unit will slide around as the collar rotates on your dog’s neck.

A simple way of stopping this from happening so often is to attach a small piece of velcro/hook-and-loop to the back of the Fi GPS unit and the part of the collar you want it to stay on.


How much does the Fi Dog Collar cost?

The Fi Smart Dog Collar costs $149 at the time of writing this article – that includes either a grey, yellow, pink, or blue collar and the main matchbox-sized GPS device mounted on it, together with the base station that you plug in at home.

If you use our code 4C83FW via this link you’ll receive an extra band free of charge which is nice if you like to mix-up your look to keep your instagram followers entertained. 🙂

Use our exclusive coupon code ‘TK25‘ via the link below to get $25 OFF your Fi Collar order.

You may also wish to purchase a Fi Collar subscription, as this is needed to access all the GPS-specific features used by the Fi collar, including the important ‘lost dog mode.

The subscription costs $99/year, or $8.25/month, and gets your dog’s collar added as a device to the LTE-M low power cellular network, which was specifically designed for such devices, and offers 20-30% more cellular coverage in the US than 3G networks.

My parents have this subscription, so this Fi collar review is as in-depth as it could be, covering the GPS-specific features of the Fi Collar.

  1. THANK YOU!!! I have breakaway collars I use when the dogs are home alone as well as a few themed collars and I really wanted to move the Fi to existing collars I owned. This is so simple but worked so well!

  2. Thanks for this. I just bought a fi collar and was really sad at the thought of letting go of her ruffwear collar (same one) for the fi collar. I love this collar and I also love that the tags are separate from the leash loop. I’m excited to try this

  3. Thank you so much for sharing this! We had bought a Rope Hounds collar for one of our dogs because I felt better about how the FI tracker attached to it, but to be honest, I didn’t love the print of the collar like I thought I would. I just got our dogs Max & Neo collars and used this tutorial to take add the FIs to them. They are perfect for now.

  4. Thanks for documenting this! I love the Fi, but never understood why they didn’t offer some sort of universal mount so you could use it on any collar. This solution is great! Still messing around with how to minimize the sliding around, but otherwise, this is great.
