Dog Behavior is Owner-Dependent
ScienceDaily (May 1, 2009) — Many dogs are put down or abandoned due to their violent nature, but contrary to popular belief, breed has little to do with a dog's aggressive behaviour compared to all the owner-dependant factors. This is shown in a new study from the University of Córdoba, which includes breeds that are considered aggressive by nature, such as the Rottweiler or the Pit Bull.
The conclusions, however, are surprising: it is the owners who are primarily responsible for attacks due to dominance or competition of their pets.
The research team from the University of Córdoba (UCO) has determined a series of external factors which are inherent to the dogs in order to understand their aggressiveness, and they have observed that external, modifiable and owner-dependent factors have a greater influence on the animals.
According to Joaquín Pérez-Guisado, the main author of the study and a researcher from the UCO, some of the factors that cause aggressiveness in dogs are: first-time dog ownership; failure to subject the dog to basic obedience training; spoiling or pampering the dog; not using physical punishment when it is required; buying a dog as a present, as a guard dog or on impulse; spaying female dogs; leaving the dog with a constant supply of food, or spending very little time with the dog in general and on its walks.
"Failure to observe all of these modifiable factors will encourage this type of aggressiveness and would conform to what we would colloquially call 'giving our dog a bad education'", Pérez-Guisado explains to SINC.
The study, which has recently been published in the Journal of Animal and Veterinary Advances, is based on the following fact: approximately 40% of dominance aggression in dogs is associated with a lack of authority on the part of the owners who have never performed basic obedience training with their pets or who have only carried out the bare minimum of training.
Breed has less influence on aggressiveness
The Spanish researchers studied 711 dogs (354 males and 357 females) of which 594 were purebred and 117 were half-breed dogs older than one year of age. Among the breeds observed were the Bull Terrier, the American Pit Bull Terrier, the Alsatian, the Boxer, the Rottweiler, the Doberman, as well as apparently more docile breeds such as the Dalmatian, the Irish Setter, the Golden Retriever, the Labrador Retriever, the Miniature Poodle, the Chihuahua, the Pekinese, or the French Bulldog, which also exhibit dominant behaviour.
According to Pérez-Guisado, certain breeds, male sex, a small size, or an age of between 5-7 years old are "the dog-dependent factors associated with greater dominance aggression". Nevertheless, these factors have "minimal effect" on whether the dog behaves aggressively. Factors linked to the owner's actions are more influential.
To correct the animal's behaviour, the owner should handle it appropriately and "re-establish dominance over the dog", the researcher adds. In terms of physical punishment, Pérez-Guisado points out that "this method cannot be used with all dogs given the danger involved, although it could be used to re-establish dominance over puppies or small and easy-to-control dogs". However, "it should never be used as justification for treating a dog brutally, since physical punishment should be used more as a way to frighten and demonstrate the dominance we have over the dog than to inflict great suffering on the animal", the vet states.
According to the researcher, "dogs that are trained properly do not normally retain aggressive dominance behaviour". Pérez-Guisado attributes this "exceptional" conduct to the existence of some medical or organic problem, "which can cause changes in the dog's behaviour"

What Really Prompts the Dog's 'Guilty Look'
ScienceDaily (June 14, 2009) — What dog owner has not come home to a broken vase or other valuable items and a guilty-looking dog slouching around the house? By ingeniously setting up conditions where the owner was misinformed as to whether their dog had really committed an offense, Alexandra Horowitz, Assistant Professor from Barnard College in New York, uncovered the origins of the “guilty look” in dogs in the recently published “Canine Behaviour and Cognition” Special Issue of Elsevier’s Behavioural Processes.
Horowitz was able to show that the human tendency to attribute a “guilty look” to a dog was not due to whether the dog was indeed guilty. Instead, people see ‘guilt’ in a dog’s body language when they believe the dog has done something it shouldn’t have – even if the dog is in fact completely innocent of any offense.
During the study, owners were asked to leave the room after ordering their dogs not to eat a tasty treat. While the owner was away, Horowitz gave some of the dogs this forbidden treat before asking the owners back into the room. In some trials the owners were told that their dog had eaten the forbidden treat; in others, they were told their dog had behaved properly and left the treat alone. What the owners were told, however, often did not correlate with reality.
Whether the dogs' demeanor included elements of the "guilty look" had little to do with whether the dogs had actually eaten the forbidden treat or not. Dogs looked most “guilty” if they were admonished by their owners for eating the treat. In fact, dogs that had been obedient and had not eaten the treat, but were scolded by their (misinformed) owners, looked more “guilty” than those that had, in fact, eaten the treat. Thus the dog’s guilty look is a response to the owner’s behavior, and not necessarily indicative of any appreciation of its own misdeeds.
This study sheds new light on the natural human tendency to interpret animal behavior in human terms. Anthropomorphisms compare animal behavior to human behavior, and if there is some superficial similarity, then the animal behavior will be interpreted in the same terms as superficially similar human actions. This can include the attribution of higher-order emotions such as guilt or remorse to the animal.
The editor of the special issue, Clive D.L. Wynne of the Department of Psychology, University of Florida, explained, “this is a remarkably powerful demonstration of the need for careful experimental designs if we are to understand the human-dog relationship and not just reify our natural prejudices about animal behavior.” He pointed out that dogs are the oldest domesticated species and have a uniquely intimate role in the lives of millions of people. Recent research on dogs has indicated more human-like forms of reasoning about what people know than has been demonstrated even in chimpanzees.
