The best way of training your dog to use an agility tunnel is by taking a step-by-step approach. Don’t expect too much of your furry friend, too soon. Your first step is to let them see the tunnel, have a sniff around, and become used to it. When you first try to get them to go inside, you can fold the tunnel up to shorten it. They should be able to see you or another familiar face waiting at the other end. Call your dog and gently tap the bottom of the tunnel to reassure them that it is safe to come through. Once they have made it to the other side, you should reward them with a treat, so they naturally make a positive association with it.
Over time, you will gradually be able to lengthen the tunnel as they become used to running through it. And when this starts to become a little boring, you can start to lay it in different shapes to present them with new challenges. If your dog is especially nervous or anxious, it is likely to take time for them to build up confidence.
