Abstract: Objective The guide dogs’ working status of Labrador retrievers was evaluated by complex environment test, to explored the relationship between exploratory and working status of Labrador retrievers. Method Using the improved DMA test method of Swedish Working Dog Association, 41 Labrador dogs from Dalian training base of Chinese guide dogs were evaluated, and the dogs were divided into groups according to the score of exploratory behavior. Design a test method for complex environment, score the working state of guide dogs under different environmental stimulation conditions, analyze whether there are differences in the working state scores of different exploratory guide dogs in complex environment, and explore the relationship between exploratory and guide dogs’ working state. Result There were significant differences in the working state scores of the three groups of seeing-eye dogs under the stimulation of novelty objects (P<0. 05) , and there were significant differences in the working state scores of seeing-eye dogs with different genders under the stimulation of lighting and sound in complex environment (P < 0. 05) . Conclusion The working state of dogs with high exploratory ability is less affected when facing novelty objects. Under the condition of light and sound stimulation, the working state of male dogs is less affected. Exploratory males are more adaptable to complex environments.
