Descriptive study on aggressive behavior in dogs from Sorriso and Sinop/MT, Brazil

Abstract

The goal of this research was to establish and qualify the types of aggressiveness in dogs from Sinop and Sorriso/MT, Brazil, in order to draw a profile of the main breeds raised in these cities. For this purpose, an investigative survey was conducted through interviewing the owners of the animals, to characterize the aggressive behavior of their pets. Five breeds were evaluated (Pit Bull, Doberman, Poodle, Rottweiler and Duchshund), plus one group of mongrel dogs. The concept that the Pitbull is an aggressive dog was put to the test, and breeds like the Poodle and Duchshund showe the highest percentages for almost all forms of aggression assessed. The Rottweiler stood out in the characteristic of aggression toward the owner or family members, and also territorial aggression. The Pitbull had a significant result for aggression toward other animals in the same house. The Poodle and Doberman pinscher breeds, along with Duchshund, proved that are more aggressive that Pitbull and Rottweiler, despite of being small breeds. We could conclude that the behavior study of the breeds, in what concerns to aggressiveness, is of paramount importance to set a breed that best suits the owner’s conditions.
