Upgrade any fabric collar or Endurance Collar to be Fi Compatible.
This listing cannot be purchased individually, it must be purchased with a collar.

Note: the sizing change with adding this option
The Fi changes how far the collar can adjust, so keep an eye on sizing. The sizing you select on this listing is the size we will make your collar.

The original fi device connectors are 1" wide, so for anything other than 1" wide straps on an original fi collar we'll use biothane to connect it together (i.e. for the 3/4" & 5/8" widths)

The new Fi 3 has 1" or 3/4" connectors, so we'll use those for those widths, and we'll use biothane to attach 3/4" connectors to a 5/8" strap for our smallest size.

No collar is indestructible, customers should check for wear and tear of their dog's collars and replace when necessary. It is the full responsibility of the customer to determine the suitability of the collar for their pet.

We have a small (14 pounds) rescue we needed to fit with a Fi tracking device. The collars that come with the Fi trackers are designed for much larger dogs and were WAY to big for her. I ordered a Custom Fi collar from Zaley Designs a year and a half ago and it was one of the best purchases I have ever made. The Zaley collar is perfect and just ordered two more. If you have a small dog and a Fi tracker, this is the best solution I have found and there are many different styles and options to choose from. Plus it’s great to know that you are supporting a great small business. The customer service was exceptional!

Love the products

Just placed a second order for a collar of same style so matches leash handle. One buckle, one martingale style and both are Fi3 compatible. They are not only adorable but also extremely well made.

Glad I made this purchase!

I'm so happy I decided to get such a cute, custom Fi collar for my Pomsky instead of just sticking with the common supplied Fi collar. She looks so cute wearing her Peanut Butter and Jelly sandwich collar.
