For many large companies it is a problem to detect the exact location of a leakage. Mainly oil or gas. This may involve digging up meters or kilometres of pipeline to find the exact place of the leakage.
Pipeline detection dogs can indicate the exact location of the leakage within approximately a meter. The dogs are trained on an agent which is added into the system which dogs can be trained to recognize. This will save enormous amounts of work, disturbance of environment and it out ways many modern technology detection systems, which in turn is more cost effective.
