Fi Dogs GPS Compatible Martingale Collar

The Fi martingale collars require the most precise neck measurements. Due to the style of the collar, we can only give about an inch of "wiggle room" in either direction from the neck size you give. PLEASE ensure you are giving us the correct neck measurement for your pup, which is the collar circumference you desire while the martingale chain is fully open and sitting around your dog's neck like any other collar would. 

You can choose up to three colors. The primary color will be the "background" color. The secondary color will be the color of the adjustable piece (with the holes punched in it) as well as the smaller loop securing the other end of the martingale chain. The Fi endloop color will be the color of the small pieces that hold your Fi endlinks in place.
