The tracking of people by trained dogs is based on the recognition of carboxylic acids in the sweat from feet.


- Trained dogs are able to track individuals by following their scent, which is primarily derived from the sweat they produce.
- Sweat is composed of various compounds, including carboxylic acids, uric acid, sugars, and salt.
- Among these compounds, carboxylic acids play a significant role in distinguishing the scent of an individual.


- Sweat is a complex mixture of water, electrolytes, minerals, and organic compounds.
- Carboxylic acids, also known as organic acids, are a class of compounds that contain a carboxyl group (-COOH).
- These acids are produced as a byproduct of metabolic processes in the body and are excreted through sweat.


- Trained dogs have an exceptional sense of smell, which allows them to detect and differentiate between various scents.
- Carboxylic acids present in human sweat have a distinct odor that can be detected by dogs.
- Each individual has a unique combination and concentration of carboxylic acids in their sweat, which forms a specific scent profile.
- Dogs can be trained to recognize and track this scent profile, enabling them to identify and follow a specific person's trail.


- While carboxylic acids are the primary compounds that dogs track in human sweat, other compounds also contribute to the overall scent.
- Uric acid, sugars, and salt are present in sweat and may add additional information to the scent profile.
- However, carboxylic acids are the most distinguishing compounds and provide the main olfactory cues for trained tracking dogs.


- The tracking of people by trained dogs is primarily based on the recognition of carboxylic acids in the sweat from feet.
- These acids provide a unique scent profile that allows dogs to differentiate between individuals and follow their trail accurately.
