Träning och test med hund på brunbjörn (Ursus arctos) i hägn : långsiktiga effekter på beteenderepertoaren

Abstract: The main cause of adult Brown bear (Ursus arctos) mortality in Sweden is due to legal hunting and there has been a game culture for this specie since 1943. Today there is two game enclosures for brown bears located in Sweden, one in Almunge and one in Junsele. The main reason for training dogs on bears in these enclosures is to ensure bear-safe dogs both for encounters when tracking bears that been wounded due to hunting or accidents, for bear hunting and in case of bear encounters when hunting other game species in bear-tight areas. Although the ideas would be favourable for either the safety of the hunters and their dogs or the welfare of potentially injured wild bears, the welfare of the animals used in these operations must be taken into consideration. In Chapter 3 1§ p.1 of the Swedish Animal Protection Act it states that it is forbidden to use animals in training or tests in such a way that they are subject to suffering. In 2019, a government assignment came to the Swedish National Board of Agriculture and the Swedish Environmental Protection Agency to investigate whether training for pre-trial and predatory tests in game fences will cause suffering for the animals involved. This pointed out that there was a need for studies within the subject and this study is carried out in collaboration with SCAW without any connection to the mentioned government assignment. The aim of this study was to investigate the effects on the behaviour of fenced bears after being exposed to training/test with dogs. This was made to give an insight into the welfare of the bears from an ethological perspective. Results showed that the inactive behaviours had the highest proportion of observations throughout the study for all three bears. It also showed that one of the individuals performed stereotypic behaviour, pacing, before and after exposure but not during control observations. There was a connection between stereotypic behaviour and whether a training/test had been carried out. A pattern was seen between proportion of observations of stereotypic behaviour and number of trainings/tests that same day. Active behaviours were most frequent on the day with the highest number of trainings/tests and the proportion of observations of inactive behaviours increased with the number of trainings/tests. A conclusion was made that the behaviour was affected by the number of trainings/tests to some extent. There was also a pattern for fence usage and training/test under the conditions that the bears were not disturbed more than normally. Lastly the results showed that humans and more than one dog at the same time resulted in a stronger stress response than usually observed and the results exhibited an individuality in the experience and eventual stress management after exposure. The study showed that behaviors that correspond to stress and negative experiences of exercise were noted in the study, which indicates that there are welfare problems. Training with dogs on wild animals that subject the animal to stress can cause suffering, based on the above study this cannot be ruled out. To be able to understand with greater certainty how training / test occasions with dogs affect the well-being of bears, more studies on the behavior and physiological stress response of bears are needed. Research should also be devoted to exploring different alternatives to live animals. Keywords: Ursus arctos, brown bear, dog, dog training, behaviour, stress, welfare, natural behaviour
