(Reuters) - A South Korean startup has developed an AI-powered dog collar that can detect five emotions in canines by monitoring their barks using voice recognition technology.

The Petpuls collar can tell pet owners through a smartphone application if their dogs are happy, relaxed, anxious, angry or sad. It also tracks dogs' physical activity and rest.
