Area Search for Person Tracking Dogs

Area search is one of the most important disciplines in person tracking dog training. Unlike mantrailing, where the dog follows an individual scent trail, in area search the dog systematically searches a defined area to find missing persons. This method is particularly effective when there is no concrete trail or the search area is very large.

What is Area Search?

Area search, also known as "Area Search" or "Grid Search", is a systematic search method in which a defined area is divided into sections and searched sequentially. The dog works more independently than in mantrailing and uses its sense of smell to detect human scents in the air or on the ground.

Differences to Other Search Methods

Basics of Area Search

Scent Perception in Area Search

In area search, dogs primarily use air scent (convection scent), which is transported by wind and thermals. Unlike mantrailing, where the dog has ground contact, in area search the dog must pick up scents from the air and locate their source.

Important Factors:

• Wind direction and strength: Wind transports scents and influences search direction
• Temperature and thermals: Warm air rises and can transport scents to higher elevations
• Humidity: High humidity keeps scents in the air longer
• Terrain structure: Hills, valleys and vegetation influence scent distribution

Search Strategies

Area search can be conducted using various strategies:

Grid System (Grid Search):

• The search area is divided into uniform squares or rectangles
• Each section is systematically searched
• Guarantees complete coverage of the area
• Ideal for large, open areas

Zigzag Pattern:

• The handler guides the dog in zigzag lines through the area
• Effective for medium-sized search areas
• Enables good wind utilization
• More flexible than grid system

Spiral Search:

• Starting from a center, search spirally outward
• Effective for point-specific search areas
• Good for round or square areas
• Can be adapted to wind direction

Area Search Training

Prerequisites for Training

Before starting area search training, the dog should master certain basics:

• Basic commands: Sit, down, stay, here
• Leash control: Controlled movement even without leash
• Scent perception: Basic understanding of human scents
• Endurance: Physical fitness for longer search runs
• Concentration: Ability to concentrate over longer periods

Training Structure

Phase 1: Basics (Weeks 1-4)

In the first phase, the dog learns to recognize and locate human scents in the air:

1. Scent conditioning:
   • The dog learns to associate human scents with reward
   • Hidden persons in simple hiding places
   • Short distances (5-10 meters)
   • Clear indication is trained
2. Wind reading:
   • The dog learns to use wind direction
   • Training with wind vanes or smoke
   • Understanding of scent transport
   • Positioning against the wind
3. Simple search patterns:
   • Zigzag pattern in small area (20x20 meters)
   • Handler guides systematically
   • Reward for successful indication
   • Gradual enlargement of the area

Phase 2: Advanced Techniques (Weeks 5-12)

In the second phase, search techniques are refined:

1. Grid System Training:
   • Division of area into sections
   • Systematic processing of each section
   • Marking of searched areas
   • Complete coverage of the area
2. More difficult hiding places:
   • Persons in higher positions (trees, rocks)
   • Persons in depressions or behind obstacles
   • Multiple persons in the same area
   • Various weather conditions
3. Indication behavior:
   • Clear, reliable indication
   • Different types of indication (barking, bringsel, sit)
   • Indication even under difficult conditions
   • Reinforcement of indication behavior

Phase 3: Practical Training (Weeks 13+)

In the third phase, training is conducted under real conditions:

1. Various terrain types:
   • Forest areas with dense undergrowth
   • Open meadows and fields
   • Hilly terrain
   • Shore areas and wetlands
2. Weather conditions:
   • Training in various wind strengths
   • Rain, fog, snow
   • Different temperatures
   • Day and night training
3. Mission simulation:
   • Realistic search scenarios
   • Time pressure and stress situations
   • Cooperation with other teams
   • Documentation and communication

Indication Behavior

Indication behavior is crucial for the success of area search. The dog must clearly and reliably indicate when it has found a person.

Types of Indication

Barking (Verbellen):

• The dog stays with the found person and barks continuously
• Very reliable and clearly audible
• Can be heard over greater distances
• Requires training to avoid false alerts

Bringsel:

• The dog picks up a bringsel and brings it to the handler
• Indicates that a person has been found
• Enables precise localization
• Requires training of bringsel behavior

Sit/Down:

• The dog sits or lies down at the found person
• Quiet, controlled indication
• Good for sensitive situations
• May be harder to recognize at greater distance

Training the Indication

The indication must work reliably in various situations:

1. Consistency: The indication must always be performed the same way
2. Reliability: No false alerts for other scents
3. Endurance: Indication even during longer waiting periods
4. Clarity: Clearly recognizable for the handler

Practical Application

Mission Planning

Before each mission, area search must be carefully planned:

Area Delimitation:

• Clear definition of search area
• Marking of boundaries
• Consideration of danger spots
• Coordination with other teams

Search Strategy:

• Selection of appropriate search method (Grid, Zigzag, Spiral)
• Consideration of wind and weather
• Time planning and breaks
• Communication with mission control

Safety:

• Hazard recognition in terrain
• Observing weather conditions
• Equipment and emergency equipment
• Communication devices

Conducting the Search

Preparation:

• Equipment check
• Briefing with mission control
• Weather and terrain assessment
• Determination of search strategy

Search Phase:

• Systematic search of the area
• Continuous observation of the dog
• Adaptation to terrain and weather
• Documentation of findings

After Indication:

• Confirmation of find location
• Securing the find site
• Report to mission control
• Further search if needed

Common Mistakes and Solutions

Training Mistakes

Problem: Dog does not search systematically

• Solution: Clearer guidance by handler, smaller search areas, more structure in training

Problem: False alerts

• Solution: Stronger differentiation between human and other scents, clearer indication criteria

Problem: Dog loses motivation

• Solution: Varied training, appropriate rewards, sufficient breaks

Problem: Unreliable indication

• Solution: Reinforcement of indication behavior, consistent reward, clear signals

Mission Mistakes

Problem: Incomplete coverage

• Solution: More systematic approach, marking of searched areas, clear area division

Problem: Overlooking hiding places

• Solution: Training with various hiding place types, better terrain knowledge, slower search

Problem: Weather influences

• Solution: Training under various conditions, strategy adaptation, gaining experience
