Must be purchased with a dog collar
Fi Collar Add-On / End Links Only
Fi Collar Info
This is an upgrade to add authentic Fi end links to one of our dog collars in order to make it Fi Compatible. It does NOT include the Fi GPS device. 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 a 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.
Disclaimers: A Fi GPS is not included with your collar. Black Hardware is not recommended for water use. If your dog frequents the water, please select the Stainless Steel Hardware. Discounts are not valid on this product.
How To Order

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.
