Dog personality and behaviour

smartDOG

The mission of SmartDOG is to bring science close to the dog owner and at the same time do science. The founder of SmartDOG is Katriina Tiira, PhD, biologist and animal behaviour researcher with over 20 years of experience.

Background

Until 2016, all the dog behavior tests offered to the general public mainly measured the dog’s fearfulness and courage. This is probably because the dog’s traits are tested from the working dog side, and the purpose of the test was to get functional individuals for challenging tasks that require courage. However, the dog is more than just timid or bold, and many other features affect the dog’s behavior. Studies show that there are many differences between individuals in cognitive traits. These features include: impulsivity, self -control, memory, understanding people’s gestures, problem -solving ability, and how the dog mainly solves problems (independent or asking for help). These traits seem to affect trainability, learning and also the development of any problem behavior. In 2016, Katriina piloted a test battery based on the latest dog cognition research.

In addition to cognitive traits, the tests actually tell you a lot about the dog’s fearfulness and reactions to the unfamiliar tester, the new space and the test equipment. The tests clearly show the kind of fearfulness that the dog displays without being specifically pressurised. It is this very fearfulness that can usually interfere with the dog’s daily life.

The result was SmartDOG test packages that are unique in the world. These tests are conducted currently only in Finland, however smartDOG is planning to train license testers also in other countries. Currently (January 2025), there are over 7,000 dogs tested.

About me

SmarDOG Oy is a company founded by Katriina Tiira, PhD, Biologist, and Docent of Animal Behavioral Science. Katriina Tiira has over 20 years of experience as an animal behavior researcher at the University of Helsinki. For the last 15 years, Katriina has studied dog behavior and has written several scientific publications on dog behavior and cognition, and is still actively doing research on the smartDOG data. Katriina claimed her doctorate in 2001 from the University of Helsinki on the subject “Integrated Analysis of Aggression In Salmonides”, after which she continued as a postdoctoral researcher at the Academy of Finland at the University of Helsinki. Between 2008 and 2015, Katriina worked in the Post Doc researcher Prof Hannes Lohe’s Dog Genetics Research Group, studying the behavior of dogs and a genetic background in behavior. Since 2001, Katriina has been a judge for the Disabled Association’s assistant dogs, and since 2012 also a judge for the Dogs in the Educational and Rehabilitation Association’s temperament test. Training and competition experience with own dogs can be found since 1984. Working dog search, tracking, obedience, hunting trials and working trials, where best was years ago (1997 working dog Finnish Champion Bronze with a Giant Schnauzer). Katriina has had several dogs over years of different breeds, several Giant Schnauzers, a labrador, a Flat-coated retriever, a Cocker spaniel and a mixed breed. Currently, there is a Curly coated retriever and a Cocker spaniel at home.
