The program consists of multiple levels of increasing difficulty. At each level, dogs must locate lost items in well-used search areas with specific conditions such as:

• Minimum and maximum search area sizes
• Hide placement requirements (e.g., elevation)
• Introduction of distractors at higher levels

Primary Title Levels

• Lost Item Online Level I (LIO-I) – Basic level, single known hide, no distractors
• Lost Item Online Level II (LIO-II) – Increased hide elevation, continued off-lead searching
• Lost Item Online Level III (LIO-III) – Introduction of food distractors
• Master Lost Item Online Champion (MLIOCH) – Multiple item categories, increasing complexity, toy and food distractors

Specialist Titles

Beyond standard levels, teams can work toward Specialist Titles (LIO-S), which challenge dogs with:

• Multiple hides
• Distraction elements
• Large search areas
• Creative hide placements
• Distance-based finds

Examples include:

• LIO-SF (Fabric)
• LIO-ST (Technology)
• LIO-SP (Personal)
• LIO-SS (Small)
• LIO-SH (Helper – retrieve and return)
• LIO-SD (Distance – working farther from the handler)
• LIO-SV (Variable – unique search locations)
