Dogs Walked by Men Are More Aggressive

"Dogs being walked by men are four times more likely to threaten and bite other dogs and dogs on a leash are more likely to act aggressively than dogs off the leash. These are just a couple of revelations about dog walking behavior from an extensive new study that examined how a dog's age, sex and size, as well as the owner's sex and use of a leash, affect how canines act on their walks. The study, accepted for publication in the journal Applied Animal Behavior Science, surprisingly found that the sex of the owner had the biggest effect on whether or not the dog would threaten or bite another dog."
