　　Purpose: To evaluate the behavior and heart rate characteristics of Labrador dogs through the distance test (DT), and to provide effective behavioral methods and physiological basis for the pre-screening of guide dogs.

　　Method: The 60 Labrador dogs (8-15 months, 22, 38) used in this experiment were provided by the Dalian Training Base of Chinese Guide Dogs. Among the 30 successfully trained guide dogs, 30 passed the assessment after training, and the remaining 30 were regarded as improper guide dogs. In the dog's behavior test, three variables related to distance test, exploration and game invitation were used to monitor heart rate changes in real time.

　　Result: The average heart rate change of the guide dog in the distance test was significantly lower than that of the evacuated guide dog (P0.05).

　　Conclusion: In the distance test, the heart rate of the guide dog is significantly lower than that of the excluded dog. Compared with the excluded dog, the guide dog has a stable psychological quality and excellent emotional control ability. This research can provide a theoretical basis for the combination of distance testing and heart rate to predict the success rate of guide dog training.
