| Abstract: | Work examining dog personality is relatively new, so the degree to which dog personality differs by age, predicts important dog outcomes, and is correlated with human personality is unclear. In a sample of 1681 dogs (Mage = 6.44 years, SD = 3.82; 46.2% Female; 50% purebred) and their owners, older dogs were less active/excitable compared to younger dogs. Aggression toward people, responsiveness to training, and aggression toward other animals were highest among 6–8 year old dogs. Dog personality was associated with important dog outcomes—chronic health conditions, biting history, and human-dog relationships. We build on previous research by examining demographic differences in dog personality and associations between dog personality and outcomes for both dogs and humans. |
