Abstract

Behavioral problems are a major source of poor welfare and premature mortality in companion dogs. Previous studies have demonstrated associations between owners’ personality and psychological status and the prevalence and/or severity of their dogs’ behavior problems. However, the mechanisms responsible for these associations are currently unknown. Other studies have detected links between the tendency of dogs to display behavior problems and their owners’ use of aversive or confrontational training methods. This raises the possibility that the effects of owner personality and psychological status on dog behavior are mediated via their influence on the owner’s choice of training methods. We investigated this hypothesis in a self-selected, convenience sample of 1564 current dog owners using an online battery of questionnaires designed to measure, respectively, owner personality, depression, emotion regulation, use of aversive/confrontational training methods, and owner-reported dog behavior. Multivariate linear and logistic regression analyses identified modest, positive associations between owners’ use of aversive/confrontational training methods and the prevalence/severity of the following dog behavior problems: owner-directed aggression, stranger-directed aggression, separation problems, chasing, persistent barking, and house-soiling (urination and defecation when left alone). The regression models also detected modest associations between owners’ low scores on four of the ‘Big Five’ personality dimensions (Agreeableness, Emotional Stability, Extraversion & Conscientiousness) and their dogs’ tendency to display higher rates of owner-directed aggression, stranger-directed fear, and/or urination when left alone. The study found only weak evidence to support the hypothesis that these relationships between owner personality and dog behavior were mediated via the owners’ use of punitive training methods, but it did detect a more than five-fold increase in the use of aversive/confrontational training techniques among men with moderate depression. Further research is needed to clarify the causal relationship between owner personality and psychological status and the behavioral problems of companion dogs.

Highlights

3.3. million dogs enter US shelters and adoption centers each year, of which about 1 in 5 is euthanized [1]
Behavior problems are known to be the most common reason for owners to surrender their dogs to shelters, and they are significant risk factors for premature death [2,3,4,5,6,7]. These risks could be mitigated by a better understanding of the genetic and environmental factors that contribute to the development of behavior problems in companion dogs, including aspects of the owner’s personality, emotional well-being and behavior
Podberscek & Serpell [9] found that the owners of a sample of aggressive English cocker spaniels were significantly more likely to rate themselves as tense, shy, and emotionally unstable on the Catell 16 Personality Factor Questionnaire than a comparable sample of owners of nonaggressive spaniels, and Dodman et al [10] detected associations between personality factors measured by the California Personality Inventory and the expression of canine behavior problems such as dominance-related aggression, fear aggression, and separation anxiety

Summary

Introduction

3.3. million dogs enter US shelters and adoption centers each year, of which about 1 in 5 is euthanized [1]. Behavior problems are known to be the most common reason for owners to surrender their dogs to shelters, and they are significant risk factors for premature death [2,3,4,5,6,7]. These risks could be mitigated by a better understanding of the genetic and environmental factors that contribute to the development of behavior problems in companion dogs, including aspects of the owner’s personality, emotional well-being and behavior. In the case of more changeable characteristics, such as depression, the likely direction of causation is more difficult to determine
