Are small dogs more aggressive than large breeds? Kuya Kim answers

If you are afraid of dogs, you might be thinking that large breeds are scarier than than cute, smaller ones.

However, some people believe that smaller breeds are more aggressive than large dogs. Is this true?

According to Kuya Kim's report on Friday's "24 Oras," there is no concrete proof of the "small but terrible" adage when it comes to dogs.

However, a peer-reviewed study from the University of Sydney and University of Pennsylvania found that small dogs show more aggression, possibly due to their genetics.

Aside from size, other variables that can be associated with dogs' aggression include age, sex, environment, anxiety issues, and health issues, among others.
