Quick Answer

To attach a Fi compatible patch to your dog's collar or harness, first ensure the patch has hook (loop) backing and your gear has a loop strip. Align the patch evenly, press firmly, and check that it sits flat without gaps. For a permanent hold, you can also sew the patch onto a webbing collar.

What You Need Before You Start

You need a Fi Series 3/3+ compatible patch, such as the Tactipup Fi Series 3/3+ Patch, and a collar or harness with at least 1.5 inches of webbing width. The patch measures 4.5 x 1.5 inches, so it fits best on 1.5- or 2-inch collars or harnesses. If your gear doesn't already have loop fastener material, you can add a loop strip to the collar or order one with the patch.

Choosing the Right Attachment Method

Most patches use a hook backing that sticks to loop material on the collar or harness. This method is quick and lets you swap patches easily. For a more permanent fix, you can sew the patch directly onto webbing. Sewing is ideal if your dog frequently brushes against bushes or rough terrain, as it prevents the patch from catching and peeling off.

Step-by-Step Patch Attachment Guide

  1. Check Your Collar or Harness: Make sure your gear has a loop fastener strip (the fuzzy side) where you want the patch to sit. If it doesn't, you can add a loop strip to the collar or order a collar with loop already sewn on. The patch needs at least 1.5 inches of webbing width. Common mistake: trying to attach a patch to a collar that only has smooth nylon. Without loop material, the hook backing won't grip.
  2. Position the Patch Around the Fi Transmitter: Place the patch so its cutout aligns with the Fi Series 3/3+ transmitter. The patch should sit flat against the webbing, with the transmitter poking through the opening. Make sure the patch isn't twisted or bunched. Checkpoint: the transmitter should be fully exposed and not covered by any part of the patch.
  3. Press Firmly and Evenly: Starting from the center, press the patch down onto the loop material. Run your fingers along the edges to ensure full contact. If the patch has a curved shape, press along the curve to avoid air bubbles. Common mistake: not pressing hard enough, which leaves gaps that can catch on branches or other gear.
  4. Test the Hold: Gently tug the patch at each corner and along the edges. It should not lift or slide. If it moves, press again or consider sewing for a permanent fix. For active dogs, sewing is more reliable than hook-and-loop alone. If the patch still lifts after pressing, the loop material may be worn or too shallow. Replace the loop strip or switch to sewing.
