The owners completed two questionnaires: one to assess the dog's personality and one to assess the relationship between the dog and owner. 

The DPQ consists of 75 statements with responses ranked on a scale of 1 to 7 in order of agreement, with 1 being “Disagree Strongly” and 7 being “Agree Strongly”.

These 75 statements are grouped into five Factors: Fearfulness, Aggression Towards People, Activity/Excitability, Responsiveness to Training, and Aggression Towards Animals. Each question represents a “Facet” of its respective Factor.

MDORS is a validated and widely used relationship scale that assesses both the perceived benefits and costs of the dog-human relationship.

It contains 28 questions divided into three sub-scales: Dog-Owner Interaction, Perceived Emotional Closeness, and Perceived Costs.
