Uporabnost termografije kot kazalnika agresivnosti pri delovnih psih

Hernaus, Živa (author), Zupan Šemrov, Manja (mentor)

Na temo agresije pri psih je bilo v preteklosti narejenih že veliko raziskav. Kljub temu potencialna uporaba termografije za ugotavljanje predispozicij posameznega psa za izražanje določene oblike agresije ni bila obširno raziskana. Cilj diplomskega dela je objektivno določiti parametre agresivnega obnašanja in fiziološkega profila agresivnega psa na podlagi infrardeče termografije, za katero predvidevamo, da je učinkovita neinvazivna metoda za raziskovanje stresnih znakov pri psih. V raziskavi sta sodelovali dve skupini psov, in sicer 15 psov brez zgodovine agresivnega obnašanja in 16 delavnih policijskih psov, ki pri svojem delu izražajo agresijo. Test socialno sprejemljivega obnašanja, ki je zasnovan tako, da iz psa izvabi agresivno obnašanje, je bil izveden na zunanjem poligonu in je vseboval 16 posameznih nalog. Površinsko temperaturo telesa psov smo merili pred in po opravljenem testu. Površinsko temperaturo obraza smo merili frontalno, prav tako pred in po testu ter po vsaki posamezni nalogi. Pri merjenju telesne temperature in temperature obraza pred in po testu nismo našli statistično značilnih razlik med agresivnimi in neagresivnimi psi. Pri merjenju površinske temperature obraza med testom pa smo odkrili višje temperature pri agresivnih psih, kar je v nasprotju z našo hipotezo, ter zabeležili statistično značilne vplive pri dolžini dlake, zračni vlagi in hitrosti vetra. V naši študiji smo ugotovili, da je merjenje temperature med testom boljši indikator čustvenega stanja kakor pred in po opravljenem testiranju in da se med izražanjem agresivnega obnašanja aktivira kardiovaskularni sistem.

• Title: Usefulness of thermography as an indicator of aggressiveness in working dogs

Abstract

There has been a lot of research on aggression in dogs in the past. However, the potential use of thermography to identify the predisposition of an individual dog to express a particular form of aggression has not been extensively investigated. The aim of this thesis is to objectively determine the parameters of aggressive behaviour and the physiological profile of an aggressive dog based on infrared tremography, which we hypothesize to be an effective non-invasive method for investigating stress signs in dogs. Two groups of dogs participated in the study, 15 dogs with no history of aggressive behaviour and 16 working police dogs that show aggression in their work. A socially acceptable behaviour test, designed to elicit aggressive behaviour from the dog, was conducted on an outdoor polygon and consisted of 16 individual tasks. The dogs' body surface temperature was measured before and after the test. Facial surface temperature was measured frontally, also before and after the test and after each individual task. When measuring body temperature and facial temperature before and after the test, we found no statistically significant differences between aggressive and non-aggressive dogs. However, when measuring facial surface temperature during the test, we found higher temperatures in aggressive dogs, contrary to our hypothesis, and statistically significant effects for coat length, humidity and wind speed. In our study, we found that temperature measurement during the test is a better indicator of emotional state than before and after the test and that the cardiovascular system is activated during the expression of aggressive behaviour.
