据估计，目前有200多只助燃剂探测犬(ADC)在全美协助火灾调查。在许多情况下，他们的能力和可靠性受到了质疑。皮内拉斯县法医实验室评估了42支助燃剂检测犬团队的能力，包括区分普通促进剂和热解产品、检测低浓度的普通促进剂、精确定位促进剂以及检测不同类别的促进剂。归根结底，精确度、可靠性和整体效果因犬只和训导员的不同而不同，似乎受到犬只的训练、处理和维护的某种限制。虽然大多数警犬团队的表现都非常好，可以成为火灾调查的资产，但一些团队被证明是不可靠的。不能对所有的促进剂检测犬作出普遍的认可或谴责；但是，可以对特定的犬队和训练员进行认可。每个工作的犬队都应该独立进行评估。常规测试是确定犬的能力和局限性的必要手段。
It is estimated that over 200 accelerant detection canines (ADCs) are currently assisting in fire investigations throughout the United States. On many occasions, their ability and reliability have been called into question. The Pinellas County Forensic Laboratory evaluated 42 accelerant detection canine teams in their ability to discriminate between common accelerants and pyrolysis products, to detect common accelerants at low concentrations, to precisely locate accelerants and, to detect different classes of accelerants. Ultimately, the accuracy, dependability and overall effectiveness varied from canine to canine and handler to handler and appeared to be somewhat limited by the canine's training, handling and maintenance. While most of the canine teams performed extremely well and could be an asset to fire investigation, some proved to be unreliable. A universal endorsement or condemnation of all accelerant detection canines could not be made; however, endorsements of specific canine teams and trainers were possible. Every working canine team should be evaluated independently. Routine testing is imperative to establish the canine abilities and limitations.
