Abstract

Reliability is one of the most important aspects of the behaviour observations measuring personality traits in animals. The most fundamental way to test reliability is the assessment of the test–retest consistency. On the other hand, in situations where social interaction between a human participant and the animal subject is at the scope of the study, the behaviour of the humans in the test situation should be restricted by a set of rules. However, if more than one experimenter participates in the observations, the similarity of the behaviour of different persons is an important aspect of the reliability of the study.

In our first study we investigated the consistency of dogs’ behaviour during approach by a person in a friendly and in a threatening way, repeating the test either immediately after the first test or at least 6 months later. We found that the dogs’ sensitivity to the human's behavioural cues in this situation proved to be consistent over repetition when the second test was performed approximately 1 year after the first test, but it was not the case when the time elapsed between test occasions was a few seconds. The detailed analysis indicated that dogs performing extreme behaviour (friendly or threatening) tended to show more conservative responses than dogs showing intermediate reactions when the stranger approached threateningly. Nonetheless, the reaction of the dogs failed to be in accordance with the opinion of the owners about the dogs’ behaviour in similar situations in everyday life.

In the second study we examined the consistency of the dogs’ behaviour in the same situation when confronted with two different unfamiliar persons immediately after each other. The consistency of the dogs’ response to the two experimenters was found to be reliably high.

In sum, this test procedure proved to be reliable enough to be a valuable measure of a definite part of the personality characters of dogs.

Abstract

Partner choice is strongly affected by similarity in physical and psychological characteristics. Although there is a popular belief that dogs share similar personality characteristics with their owners, no studies have yet addressed the topic. Here, we tested for associations between the dog and owner personality in two countries (Austria and Hungary) and found significant positive correlations between owners and their dogs in all the five investigated personality dimensions (neuroticism, extraversion, conscientiousness, agreeableness, and openness). This similarity could not be attributed solely to the owners’ self-projection, since the similarity in the first four dimensions was also significant when an independent peer person assessed the dog instead of the owner. The similarity was not affected by the length of ownership, however, we found cultural differences in the correlation pattern; more and stronger correlations were found in the Hungarian sample. Moreover, in multi-dog households the dogs’ similarity patterns complement each other, suggesting possible differences in the dogs’ role. Our results provide the first evidence that dogs do resemble their owners suggesting potential applied utility as well as indicating that dog–owner relationship could be a useful model of human social relationships.

Abstract

The relationship between pet-keeping and owner personality has attracted considerable attention. Little focus, however, has been directed towards the personality of pet owners in relation to the type of pet owned. This study therefore explored the personality of pet owners in relation to the type of dog breed owned, focusing specifically on owners of breeds widely considered to be “aggressive” versus those more generally perceived as “non-aggressive”. One hundred and forty seven owners of “aggressive” (German shepherd dogs, Rottweilers) or “non-aggressive” (Labrador retrievers, Golden retrievers) dog breeds completed the Eysenck Personality Questionnaire short scale. Breed of dog owned was significantly related to owners’ psychoticism scores, with people who kept “aggressive” dogs having significantly higher scores on this trait than owners of “non-aggressive” dogs. Dog breed ownership was not significantly related to neuroticism, extraversion or lie scale scores, although male owners of “aggressive” dogs were found to be significantly less neurotic than women who kept “aggressive” or “non-aggressive” dogs. Overall, findings suggest that there is a significant relationship between dog breed ownership and specific personality traits, with owners of breeds widely considered to be “aggressive” harbouring more psychotic tendencies than people who choose to keep dogs with a reputedly less aggressive temperament.
