If a dog is swimming and detects a substance, they will circle or repeatedly return to that area. Additionally, dogs will communicate their findings to their owner through behaviors like sitting, laying down, or stopping at the site. Some dogs may even provide an audible sign if trained to do so. Even if they haven’t been specifically trained to identify a substance, dogs will still show interest in the scent they have found.

History Behind Dogs Smelling Drugs in Water
Dogs have always been beneficial in criminal investigations because of their ability to detect objects and substances like drugs in different materials. The use of dogs in policing became more prevalent in the 20th century, with breeds like German Shepherds being considered ideal for identifying and apprehending criminals. Over time, dogs have been trained to recognize specific scents and respond to hostile or violent behaviors. They now assist in various situations, including detecting drugs, locating explosives, search and rescue missions, supporting military personnel, and apprehending criminals in security, military, public, and airport settings.
Science Behind Dogs Smelling Drugs in Water
Dogs have a significantly stronger sense of smell than humans. They have 300 olfactory receptors compared to our 6 million, and their brain’s ability to interpret smells is 40 times more powerful. Dogs have a separate system for smelling and breathing, allowing them to analyze smells more effectively. Their sense of smell is so powerful that they can detect a tablespoon of sugar in a million gallons of water. This explains their ability to locate small amounts of drugs in water during search and rescue operations.
Training a Dog to Smell Drugs in Water
Training a dog to smell drugs in water can be a challenging and time-consuming process. The right breed of dog must be chosen, and the puppy should be trained to be obedient and responsive to commands and gestures. Positive reinforcement is used for rewards during training. The dog must also be fit, agile, confident, and free from physical ailments that could affect their performance. Play is used as a method to train dogs to identify drugs, starting with playing tug of war using a clean towel and gradually associating the smell of drugs with the game. Dogs are trained to only perform one type of search as they cannot communicate the exact substance they have detected to their handler.
