Fi Compatible Dog Collar UPGRADE
Fi Collar Info
This is not a dog collar, it is an upgrade to make any of our collars Fi Compatible. You’ll need to add this upgrade to your cart along with any of the collars on our website (ready to ship or made to order, any style and width) to add the ability to secure your Fi GPS to the top of your collar.
Sizing: Because of where the tracker sits on top of our collars, our standard sizing will lose the first 2” of adjustment. This is reflected in the sizes you choose above for extra precaution.
Our layered Fi-compatible collar style is our new favorite! You can now make any of our collars Fi-compatible and no longer need to worry about your dog pulling on the Fi links!
Please note: we do not sell the Fi GPS device and only supply compatible collars using authentic Fi links.
Disclaimers: Black Hardware is not recommended for water use. If your dog frequents the water, please select the Stainless Steel Hardware. A Fi GPS is not included with your collar. Discounts are not valid on this product.
How To Order
You may choose any size/width/style for your Fi Collar
-Add any collar of your choice to your cart. All collars can be seen here

Q: What size collar does my dog need?
A: Your dog's collar should be able to adjust up and down from their neck size for the perfect fit. Example: an adult dog with a 14in neck should wear a small, but a puppy with a 14in neck should wear a medium.
When ordering slip-on styles such as fabric martingales or limited slips, make sure the size range you select will fit over your dog's head and still fit around their neck.
We try to avoid returns/exchanges, especially for fi collars. However, if it doesn't work out, the buyer (you) is responsible for a 50% restocking fee and all return/exchange shipping costs for Fi Compatible Collars that need to be returned/exchanged. This is due to these collars being custom-made to fit your pup along with having to punch holes into a collar, making it no-longer sellable.
