Left- pawed dogs likely to be more aggressive
A new report shows that “left pawed dogs” are likely to be more aggressive to strangers than “right pawed dogs”
It appears that dogs, like humans, have a paw which provides more use to them. Instead of left handed and right handed, research shows that dogs can be left pawed and right pawed. Researchers have looked closer into this theory and have made a series of tests. This includes evidence that dogs who prefer to use their left paw are likely to be more aggressive to strangers.
The tests were carried out on a group of dogs first of all to find which paw they preferred and then traits like excitability and attention seeking were tested however no credible correlation was found except in aggression.
The Telegraph gives an explanation that the left paw is controlled by the right hemisphere of the brain which is associated with more negative emotions. Scientists believe that the findings reflect was has been known previously in humans.
Dr Luke Schneider from the University of Ardelaide who was part of the study said that:
“We found that dogs with a preference for left paws were reported by their owners to show high levels of aggression towards strangers. The left pawed dogs scored almost twice as high as ambilateral (ones with no preference) and also higher than dogs with right paws.
“There is research in the human world as well that positive and negative emotions can be located in the left and right hemispheres and it seems to go the same way in humans and other animal species, that the negative emotions are located in the right hemisphere. There are many, many overlaps between human and animal brains.”
Unlike humans where the majority of us are right handed, in the case of dogs it is pretty much equal. In this study, around 33% were found to be left pawed, 33% right pawed and the remainder did not have a preference and could use both paws equally.
Because the study only involved a small number of dogs, the researchers now want to carry out a larger study with more animals especially those that are known to be aggressive. The study also only involved the preference of the front paw. Dogs also demonstrate preference in their hind legs for example one usually leads when the dog runs.
