Running through a tunnel for a dog is one of the first challenges for agility training. Dogs who go through agility training can also go through agility competitions. Some show dogs will need to be able to run through tunnels. Dogs who learn to hunt can also benefit from being trained to run through tunnels. Running through a tunnel for a dog can be quite challenging because they're not sure what's inside and what benefit the tunnel has for them. But you can easily teach your dog to run through a tunnel with a little bit of time and patience. Dogs who have agility training and can burrow and run through simple tunnels all the way to advanced tunnels can be trained to do other things as well. This is a fun trick to do with your dog, especially if you plan on furthering his training and agility.
Training your dog to run through a tunnel simply starts with trust. Your dog needs to trust that what's inside the tunnel it's going to be safe for him. To develop this trust, you may need a partner to help so one of you is on one end of the tunnel and someone is on the other end of the tunnel. Special treats, as well as toys, to put in the tunnel may also further this training along a little faster. You can teach any dog to run through a tunnel, however, the younger the dog is the easier agility training is as well. Tunnel running is typically done with smaller dogs rather than large breeds, however, large breeds also may need to get through tunnels as long as they are the proper size.
Training your dog to run through a tunnel is going to require patience and repetition. Set some time aside each day to practice this trick so your dog does not forget the commands and his expectations as he runs through tunnels. High-value treats at the other end of the tunnel will help your dog get all the way through. Obviously, you will need a tunnel. A child's play tunnel will work just fine as long as your dog fits inside. You can find agility dog tunnels for training purposes--find something easy that your dog will fit into that you can change the size and shape of as your challenges increase.
