Scientists have studied the characteristics of more than 20 dog breeds to find out the link between the breed of dogs and their aggression towards humans

Scientists from the University of Helsinki have found a link between the breed of dogs and their aggression.

In the course of the study, experts studied the behavior of about 9000 pets and found the personality traits of a dog that influence its tendency to aggressive behavior towards humans.

“Small dogs are more likely to behave aggressively than medium to large dogs. But because of their size, they are often not viewed as threatening, and therefore bad behavior is overlooked,” the scientists said in a report. 

The study published in Scientific Reports also showed that males are more aggressive than females and spaying them has no effect on their behavior.

The scientists also found that early pet owners’ first dogs were more likely to behave aggressively.

However, the main factor that influences the aggression of an animal is its breed.   

“Breed of dogs is a factor that influences aggressive behavior more than any other variable, with the exception of old age,” the experts clarify. 

Also, they put together a rating of breeds that are more prone to aggression. Conditionally dangerous include: Rough Collie, Miniature Poodle, Miniature Schnauzer, German Shepherd Dog, Spanish Water Dog, Lagotto, Chinese Crested, German Middle Spitz, Coton de Tulear, Wheaton Terrier.
