What Are Accelerant Detection Dogs?
Accelerant detection dogs—commonly known as arson dogs—are specially trained service animals that assist professionals in fire investigations. Their job is to locate extremely small traces of accelerants that may have been used to start or spread a fire.
Because their sense of smell is far more powerful than any mechanical detection device, these dogs provide essential information that can help determine the cause of a fire.
How Accelerant Detection Dogs Work
Fire scenes are complex environments filled with debris, smoke residue, and various burned materials. Despite this, these dogs can detect:
- Gasoline
- Kerosene
- Lighter fluids
- Other fire-starting chemicals
Their noses can locate accelerant traces at levels too small for humans to identify, allowing investigators to collect targeted samples for laboratory testing.

This early detection speeds up investigations and improves the accuracy of fire-scene analysis.
Training Requirements for Accelerant Detection Dogs
Before becoming certified, an accelerant detection dog undergoes extensive, specialized training, which includes:
- Scent discrimination
- Obedience work
- Search patterns in debris and rubble
- Exposure to controlled burns
- Field simulations with investigators
Training emphasizes accuracy, confidence, and reliability, ensuring the dog can perform consistently in high-pressure, unpredictable environments.
Certification is usually completed through recognized fire-investigation training programs.
Who Handles Accelerant Detection Dogs?
These dogs work alongside highly trained professionals, including:
- Firefighters
- Fire marshals
- Arson inspectors
- Law-enforcement personnel
Handlers receive training as well, allowing them to interpret alerts, manage fire-scene procedures, and keep the dog safe during searches.
Together, the dog and handler form a skilled investigative team.
Gear and Equipment Used by Accelerant Detection Dogs
Because they work in hazardous environments, these dogs often require specialized gear, such as:
- Protective boots
- Heat-resistant vests
- Visibility harnesses
- Official designations or department patches
Handlers may also carry identification cards verifying the dog’s working status. This ensures proper recognition when entering restricted investigation zones.
The Role of Accelerant Detection Dogs in Fire Investigations
Their involvement can help:
- Pinpoint the origins of a fire
- Identify whether accelerants were present
- Support criminal investigations
- Strengthen court evidence
- Reduce investigation time
Their accuracy not only helps determine the cause of a fire but also contributes to public safety and accountability.
Conclusion
Accelerant detection dogs are remarkable working animals whose specialized training allows them to support fire investigators in complex and often dangerous environments. By detecting even the smallest traces of fire-starting chemicals, they help uncover critical evidence that might otherwise go unnoticed. With the guidance of professional handlers and the use of proper safety gear, these dogs continue to play a vital role in modern fire investigation.
