Anyone who has had a small dog slamming at their feet will say that the meanest of doggies are often the most prone to fighting.

Now, a new study has found that small dogs are almost always more aggressive than their larger counterparts.

Miniature Poodles and Miniature Schnauzers top the list of most aggressive dogs in a new study published in Scientific Reports.

The larger dogs, including Labrador Retrievers, Golden Retrievers, and Lapponian Herders, have been found to be the most docile.

Researchers at the University of Helsinki have studied more than 9,000 dogs to analyze aggressive behavior, including growls, bites and bites.

In addition to breed, other factors that impacted aggression include fear, age, the company of other members of the same species, and the owner’s previous experience with dogs.

Older dogs were more likely to be aggressive than younger ones, with scientists saying it could be due to pain from health issues, and male dogs were more likely to be aggressive than females. Smaller dogs within breeds have also been shown to be more snappy than their larger counterparts.

“It is important to understand the factors underlying aggressive behavior. Under what types of circumstances does aggressive behavior occur and what is the dog’s motive for such behavior? In normal family dogs, aggressive behavior is often undesirable, while some dogs with official functions are supposed to have At the same time, aggression can be caused by well-being problems, such as chronic pain, ”explained doctoral student Salla Mikkola from the University of Helsinki.

The study investigated aggression towards dog owners and unknown humans. Dogs were classified as aggressive if they growled often and / or attempted to bite or bite a human at least occasionally in the situations described in the survey.

Although small dogs are more likely to be aggressive, the study found that the behavior was less likely to be addressed by owners because they are not viewed as a threat.

“Aggressive behavior is a serious and common behavioral problem in domestic dogs,” the study says.

“Dogs with aggressive behavior can cause public concern by biting people and other pets, with medical and even fatal consequences for the victim.”

They add: “The severity of aggressive behavior varies from biting and snapping attacks which can even lead to the death of a victim to less severe but more common growls and barks.”

Professor Hannes Loi of the University of Helsinki added, “People who are considering buying a dog should familiarize themselves with the breed’s background and needs. As for breeders, they should also pay attention to the character of the applicants. to the mother, because both fear and aggressive behavior are inherited “.
