Abstract: Objective To analysis on the predictive effect of excitability in early screen of guide dogs, four items related to excitability, PLAY, chase test, passive test and distance test, were evaluated in temperament test of the trained dogs. Method The subjects were 92 Labrador Retrievers dogs from China Guide Dog Training Centre, guide dogs( n = 59) and elimination dogs( n = 33) . By 4 excitability tests ( PLAY, Chase, Passive, Distance) and 9 behavioral variables elated items ( interest, grabbing, tug-of-war, chase average, grabbing average, moving range, moving time, posture change, exploration) were tested in Labrador Retrievers. We were trying to analyze the difference between performances of guide dogs and elimination dogs, between dogs of different sex , between guide dogs and elimination dogs of the same sex. Result Between guide dogs ( n = 59) and eliminated dogs ( n = 33) . According to the results of statistical analysis, The 4 excitability tests average score were significantly difference between guide dogs and eliminated dogs ( t = 2. 31, P < 0. 05 ) . The passive test showed significant difference between guide dogs and eliminated dogs ( t = 2. 05, P<0. 05) . Between male ( n = 54) and female ( n = 28) ,no significant difference was detected for the scores of the 4 excitability tests between male dogs and female dogs ( t = 0. 03,P>0. 05) , the passive test in male dogs was significantly higher than that in eliminated dogs( t = 2. 56, P<0. 05) . While, Between female guide dogs ( n = 24) and eliminated dogs ( n = 14) ,The distance test in female guide dogs was significantly higher than female eliminated dogs ( t = 2. 20, P<0. 05) . In the 9 behavioral variables elated items, moving range test ( t = 2. 25, P<0. 05) , exploration test( t = 2. 20, P<0. 05) in male guide dogs was significantly higher than that in female eliminated dogs. Analysis between male guide dogs ( n = 35) and eliminated dogs ( n = 19) , no significant difference was detected for the scores of the 9 behavioral variables elated items between male guide dogs and male dogs. Conclusion This study indicated that potential that the assessment of excitability is meaningful in early screen of guide dogs.
