What is the story?
- We kept hearing from Fi owners whose dogs are escape artists – skinny-necked breeds, or anyone with a “Houdini” streak – asking for a martingale that still worked with their GPS tracker.
- So we built this collar around the Fi device itself: no separate buckle to break or snag, just a secure, no-slip loop that tightens gently when your dog pulls back.
- We layered on our favorite canvas prints, from camo to florals, so a safety collar didn’t have to mean a boring one.
- Add an optional laser-engraved nameplate for a second layer of ID right alongside your dog’s GPS tracker.
- Every collar is handmade to order in our USA studio – you’re not picking off a warehouse shelf, you’re getting one made for your dog.
Materials
- utilizes large gauge D-Rings so you can rest assured your pooch is secure on his or her lead
- made of washable nylon webbing so you can keep your pup’s specialty dog collar in pristine condition
- It’s made & engraved in the USA
- built to last—we use tough nylon webbing that can withstand over 3,100 pounds of pressure
- Personalized name plate with 2 – 4 lines laser engraving on the plate with a maximum of 20 characters per line
- Name plate is custom laser engraved with deep pristine text and your choice of font.
- Made of sturdy, washable designer canvas fabric
- Fi Compatible
Details & Fit
Important! Please keep in mind that adding a name plate will reduce the amount of adjustable room on the collar by about an 1.5″. It will also make less of the fabric visible, please keep that in mind, especially with smaller sizes!











Beautiful collar and great craftsmanship!
Love our Fi-compatible martingale Mimi Green collar! The quality is amazing and it looks great. A large fits our 40# pit/chi perfectly. Definitely recommend.
Absolutely top notch service. The craftsmanship of my collar and leash was exceptional. I will never shop anywhere other than MiMi Green for collars and leashes for my fur baby. I’m beyond pleased with my purchase. Thank you so much!
Simply love this martingale collar! Classic nautical motif. Fits the fi collar perfectly.
Great martingale collar option for Fi Series 3 transponder. I’ve gone from three collars on my fur babies to two (Fi Collar and Flea collar)
