Pipelines can develop leaks as they age, but technology can only detect 1% of leaks. Pipeline operators rely on dogs to detect leaks, as dogs can smell parts per billion compared to technology detecting parts per million. Studies show dogs have an 86% success rate detecting small leaks and can distinguish different odors. Companies now use dogs as their primary leak detection method, with dogs able to work in various temperatures and participating in intensive training. Dogs can quickly detect leaks to help prevent environmental damage and keep pipelines operating safely.
