Development and validation of a novel method for evaluating behavior and temperament in guide dogs

Area of Science:

• Animal Behavior
• Canine Psychology
• Veterinary Science

Background:

• Early temperament evaluation is crucial for guide and service dog organizations.
• Existing methods for assessing canine behavior may lack accuracy or efficiency.
• Developing reliable tools for early temperament assessment can improve guide dog selection.

Purpose of the Study:

• To develop and validate a novel questionnaire for assessing behavior and temperament in 1-year-old guide dogs.
• To identify key behavioral factors predictive of guide dog suitability.
• To provide a reliable method for early evaluation of canine temperament traits.

Main Methods:

• A questionnaire with 40 semantic differential-type scales was administered by volunteer puppy-raisers to 1097 prospective guide dogs.
• Principal components factor analysis was used to extract common behavioral factors.
• The extracted factors were validated against a guide dog school's behavioral rejection criteria.

Main Results:

• Eight stable behavioral factors were identified: stranger-directed fear/aggression, non-social fear, energy level, owner-directed aggression, chasing, trainability, attachment, and dog-directed fear/aggression.
• Three factors showed moderate internal consistency (Cronbach's alpha >= 0.72); others had lower reliability (0.53-0.61).
• The questionnaire assessments demonstrated construct validity when compared to the school's rejection criteria.

Conclusions:

• The developed questionnaire method provides a useful and accurate means of predicting guide dog suitability.
• Puppy-raiser assessments can effectively contribute to early canine temperament evaluation.
• Modifications are proposed to enhance the questionnaire's overall reliability for wider adoption.
