Physiological studies of neuroendocrine regulation confirm that aggressive behavior patterns are nearly universal in the animal kingdom. Different species of fish (e.g. Zebra Fish and Siamese Fighting Fish) are used as models for studies of animal behavior, including aggression. Despite an increased risk of injury or death, aggression frequently offers considerable benefits. It is mainly related with competition for limited resources, for example, competition for food or a mate, the establishment of territory and dominance hierarchies (a higher social status). Aggression is a kind of aversive drive to limit the freedom of other animals of the same or other species or to injure or kill them. Territorial behavior is a significant problem in farm and companion animals, not only causing economic losses but also threatening animal health and welfare. The following systems are involved in the regulation of aggressive behavior: the hypothalamo-pituitary-adrenocortical (HPA), sympathetico-medullary-adrenal (SAM), hypothalamo-pituitary-interrenal, serotonin, somatostatin, dopamine, histamine and nitric oxide pathways, as well as brain structures responsible for motivation. The aim of this article is to review the present state of knowledge concerning the neuro-endocrine modulation of aggressive behavior in animals.
Man’s connection with the dog has lasted thousands of years. Over that period, humans have influenced the physical characteristics and behavior of Canis familiaris through the process of artificial selection. The role of the domestic dog, however, has been changing along with human civilization, rendering some traits of canine behavior undesirable. The innate inclination of Canis familiaris to display aggression may influence its interaction with humans. Dogs whose behavior diverges from the norms approved by society are often placed in shelters for animals, which take care of homeless animals as well as of pets left by their owners. Consequently, animal shelters have to deal with dogs exhibiting various forms of aggressive behavior. The identification of these behavioral problems is extremely important if the animals are to be offered for adopted. In order to detect abnormal behavior in dogs, animal shelters use a number of methods, the most popular of which are various behavioral tests. The tests, however, have certain drawbacks and are not very effective in discovering behavioral problems in dogs. That is why animal shelters ought to use only reliable tests and discuss all important aspects of the dog’s behavior with its potential new owner. It is necessary to use a comprehensive approach in identifying the risks related to the dog’s aggressive behavior.
