Fi Collar Add-On for Series 3/3+ Devices, In-Line or Layered Upgrade for a Selected Dog Collar

Add Series 3 or 3+ Fi compatibility to a selected dog collar so your dog's tracking device can become part of their regular walking setup.

This upgrade is an add-on rather than a complete collar. Add the collar you want to your cart, then select either the in-line or layered installation option.

Provide your dog's neck size when ordering so the collar measurement can be adjusted if needed after the Fi add-on is incorporated.

Key Features

• Choose in-line or layered construction from the available options, allowing the Fi add-on to be configured for the selected collar.
• The layered option is recommended for strong pullers, giving pet parents a suitable configuration for dogs that place more force on their walking gear.
• For a Series 3+ device, the in-line option places it against the dog's coat as recommended for accurate analytic measuring and full performance functionality.
• Every 1.5-inch quick-release collar must use the layered configuration, making the required setup clear before you order.
• When buying more than one collar, note which collar should receive each Fi add-on so every upgrade is assigned to the intended walking setup.
