Researchers from the University of Sao Paulo (Brazil) have studied why some dogs are more aggressive than others. Or, in scientific terms, described correlations between aggressiveness and morphological, environmental and social factors, reports phys.org .The main conclusion of the study: the degree of aggressiveness is influenced by both physical characteristics (such as the weight and morphology of the skull), as well as social and environmental factors (type of household, animal life history, gender and age of the owner).
That is, the behavior of an animal is not only assimilated through education or determined by genetics, but is also the result of constant interaction with the environment.
The sample included 665 purebred and mongrel pets. Their owners filled out three online questionnaires, telling them about themselves, their pets, the environment in which they lived, and cases of aggressive behavior of dogs, such as attacks or barking at strangers. Here are some results of the study.
It is commonly thought that the aggressiveness of dogs is solely related to their breed, but in recent years this paradigm has changed: the behavior of an animal may depend on its age, gender, metabolism, hormonal balance and other factors.
The work was published in the journal Applied Animal Behavior Science.
