Are you tired of tediously picking threads to remove from your service dog's vest those "service dog in training" patches once your dog's training is complete? This is the most unusual and practical patch you'll ever own for your service dog. The service dog patch comes to you in three separate pieces. The main patch body is a 3-inch round. Centered is a graphic of a dog wearing a service dog vest with yellow background and red border. "'Service Dog" in black is embroidered above the graphic. Now, here's where it gets really interesting. The bottom third of the main patch body is Velcro. You will receive both options for filling in this space. While your dog is in training, you can place the "In Training" section on the patch. Once training is complete, simply replace the "In Training" section with its "On Duty" counterpart or switch between the two options at your convenience!
