Dogs’ character modifications in time, however these modifications happen unevenly throughout the canines’ life, and each quality follows an unique age trajectory, according to a research study released in Scientific Reports by scientists from the ELTE Eötvös Loránd University, Budapest and the University of Veterinary Medicine, Vienna. The authors likewise determined some aged canines with prospective age-related problems, which had really low issue orientation and incredibly high levels of activity.

Human character is identified by a strange dualism: it is both steady and flexible, depending upon the point of referral. If we compare ourselves to our peers, it is steady as our character rankings relative to others stay constant in time. However, character modifications ended up being apparent if we compare ourselves throughout time, as individuals end up being more diligent, more mentally steady, and more reasonable as they age.
But what about character stability and modification in canines? “Even though dog personality is a highly popular topic in the literature, there are still gaps about the long-term stability, as well as about the dynamics of personality development. That is, if personality rankings remain consistent over several years, at what age personality changes most prominently occur, and how much dogs actually change throughout their life,” describes Borbála Turcsán, very first author of the research study (ELTE, Department of Ethology).
To address these spaces, the authors examined the character of 217 Border collies throughout a broad age variety (from 6 months to 15 years) utilizing an extensive test battery referred to as the Vienna Dog Personality Test (VIDOPET). The scientists likewise welcomed the owners and the canines back to the laboratory 4 years later on, and checked 37 topics once again.
Associate Professor Friederike Range (Clever Dog Lab) explains why canines were re-tested. “Longitudinal studies covering multiple years and using the same method at both time points are very rare in the dog literature. Following up the same dogs across ~4 years allowed us to address not only the question of personality stability, but also if there are individual differences in personality development, that is, if dogs with certain personality profiles change more than others.”

The scientists revealed that pet character likewise has a ‘stable’ part, the canines’ ranks on all 5 characteristic stayed relatively constant throughout the examined period. So, for instance, the most active people in the sample stayed the most active 4 years later on. However, people with a more ‘mature’ preliminary character profile (that were less active, less curious and more oriented to issues) altered less in these qualities than their peers — comparable to what has actually been discovered in people.
To examine the basic age-related modifications in character the scientists compared the character of canines coming from 7 age. “We found that dogs’ personality changes with age, and these changes occur unevenly during the dogs’ life course, just like in humans. Crucially, however, the dynamics of change seem to be specific for each personality trait,” stated Zsofia Viranyi (Clever Dog Lab). “For example, the Problem orientation trait, which describes the dogs’ attentiveness and ability to solve problems, changes largely during early life, increasing strongly until ~6 years of age, after which further changes became negligible. In contrast, the Novelty seeking trait did not change markedly during the younger life stages, but ~3 years of age their curiosity about novel objects and situations started to decrease which continued until geriatric age.”
The Activity-self-reliance of the canines likewise reduced constantly over the canines’ life course, however in this quality the most noticable reduction happened from puppyhood to teenage years (1-2 years of age). Not all qualities revealed such a significant modification with age. For example, canines revealed just a little propensity to be much better at enduring discouraging scenarios as they age, and the canines’ level of Sociability appeared to stay consistent throughout the canines’ life course.
Interestingly, the authors likewise determined some aged canines with prospective age-related problems, which had really low issue orientation and incredibly high levels of activity. “By describing in detail the normative patterns of personality development throughout different life stages, our study can help in the identification of age-related impairments,” described Enikő Kubinyi, primary private investigator at the Senior Family Dog Project (ELTE), supported by an ERC grant. “Dogs are already recognized as a natural model for human cognitive aging, and our results suggest that similar rules govern the age-related changes in both human and dog personality.”
