Den Hunt Tunnel Requirements and Flexibility

Den Hunt events require interchangeable tunnel sections to enable clubs to offer a variety of classes and configurations. This modular approach ensures flexibility, allowing the tunnel to be adapted for different levels and challenges while maintaining NASDA’s standards for safety and functionality.

Key Features of Den Hunt Tunnels:

  1. Interchangeable Sections:
    • Tunnel sections must be modular, allowing for straight paths, turns, or varying lengths as required by different classes.
    • This ensures clubs can easily adapt to the specific requirements of each Den Hunt class.
  2. Compatibility with Existing Tunnels:
    • Clubs with tunnels designed for other organizations will likely already have many of the components needed for Den Hunt.
    • Minor adjustments, such as adding trapdoors or modifying barriers, may be all that is necessary to meet NASDA standards.
  3. Variety in Configurations:
    • The modular design allows clubs to create a range of configurations to challenge dogs at different levels, from simple straight tunnels for novice classes to more complex layouts for advanced levels.
  4. Durability and Safety:
    • Tunnels must be constructed from sturdy, dog-safe materials to withstand repeated use while ensuring the safety of both dogs and quarry.

Quarry End Specifications:

Trapdoor: A trapdoor of sufficient size must be included at the quarry end to safely remove the dog if necessary.

Barrier: The end of the tunnel must include four (4) wooden dowels, each measuring 3/4 inch to 1 inch in diameter, securely spaced to prevent the dog from reaching the quarry while allowing the dog to interact through scent and sight.

Safety and Construction Considerations:

  • Size: The tunnel must measure 9 inches by 9 inches (30 cm x 30 cm) to accommodate small earthworking dogs and others that meet this size requirement.
  • Materials: Tunnels should be constructed of durable materials, such as plywood or PVC, with interior surfaces that mimic natural conditions to encourage instinctual behaviors.
  • Stability: Ensure the tunnel and barrier are securely fixed to prevent movement during the dog’s work.
  • Ventilation: Adequate airflow must be maintained throughout the tunnel for the comfort of the dog and the live quarry.
  • Quarry Safety: The live quarry must be housed safely and humanely, with no direct contact between the dog and the quarry.
