A saliva test device includes: a means for generating an approach detection signal； a means for generating a contact detection signal； a drinking water supply unit for controlling the supply of drinking water in response to at least one of approach detection signals and contact detection signals； a pump for suctioning and collecting saliva in response to a contact detection signal； a test unit for testing whether a disease is present； a communication unit for informing test result information； a control unit for generating a system driving control signal in response to an approach detection signal, generating a pump driving control signal in response to a contact detection signal, generating a drinking water supply control signal in response to saliva collection, and controlling transmission of the test result information； and a memory for storing data. The saliva test device reduces animal stress and testing fees and improves productivity.
