    The study was aimed to evaluate the relationship between the body condition of males of farmed mink (Neovison vison) and their behaviour as well as mating performance. The observations involved 170 males of Pearl mink. Before the the breeding season, males were assigned to three groups according to their condition: Group I – very thin, Group II – thin and ideal weight, Group III – heavy and obese. On the completion of the mating season, the following reproductive indices were analysed: number of days in mating, number of matings per day and during the entire mating season, fraction of males that failed to mate, incidence of aggressive behaviours. Statistical analysis did not reveal significant differences in the mean number of days in mating, total number of matings or daily number of matings. Male condition score has a significant effect on the behaviour of the animals. The highest rate of aggressive behaviours, 16%, was observed in groups I and II, i.e. in very thin, thin and ideal weight animals. Males of group III, i.e. overweight and obese, showed one half of aggressive behaviours, about 8%. A different pattern was seen in fur chewing, since none of thin or ideal-weight males (Group II) did chew its fur. Only very thin (Group I, 2%) and obese males (Group III, 4.17%) chewed their fur. Group I comprised the lowest fraction of males that failed to mate, about 6%, compared to approx. 10% in Groups I and III each.

    Recognizing the signs of aggression in dogs is closely related to the capability of distinguishing the signals which the dog sends to the other individual. In the second part of this article, we will take a closer look at the character of particular signals and actions elicited by the signals. We also focus on how to evaluate and predict aggressive actions in dogs, so that the owner can be better prepared to interactions with the dog and to properly understand its intentions.

    Dogs' aggressive behaviors. Part I. Neurobiological mechanisms and animals' predispositions

    Excessive nervousness of a dog may not only disrupt the positive social perception of the animal, but also directly affects its health. Expertise in recognition of the dog’s emotions allows the owner to properly respond to its bad behavior, preventing the outburst of anger and a possible attack. For this reason, we attempt to characterize aggressive behaviors in dogs and the underlying neurobiological factors and genetic predisposition to aggression, and we also address some preventive measures and possible consequences of the aggressive behavior to the environment.
