What is the function of the go-to-ground tunnel?

The function of the go-to-ground tunnel is to simulate hunting scenarios, which is essential for breeds like the Jack Russell Terrier that were originally bred for hunting and vermin control. This tunnel mimics the experience of a dog going underground to flush out prey, allowing the dog to exhibit instinctual behaviors such as tracking, digging, and problem-solving in a controlled environment.

By participating in this activity, terriers can showcase their natural hunting abilities while handlers can observe how well the dog performs in a situation that closely resembles its ancestral tasks. Simulating these scenarios is crucial as it helps evaluate a dog's drive, determination, and skills that are important for their breed standard.
