23 Most Aggressive Dog Breeds, New Study Finds



Rough Collies are the most aggressive dog breed, according to a new study of more than 9,000 pets.

Research conducted by the University of Helsinki found that small dogs are more likely to behave aggressively, growl, snap and bark compared to medium and large dogs. While no dog breed is inherently vicious, other breeds are found to be aggressive, including German Shepherds, Miniature Poodles, and Chihuahuas.

The results, published in Scientific Reports, found that male dogs are more aggressive than females, while a puppy’s personality can also affect its likelihood of displaying aggression towards people.

“In our data set, the Long-haired Collie, Poodle (toy, miniature and medium) and Miniature Schnauzer were the most aggressive breeds,” Professor Hannes Lohi of the University of Helsinki told MailOnline. “Previous studies have shown fear in long-haired Collies, while the other two breeds have been shown to express aggressive behavior towards strangers.”

Elsewhere in the study, the team also found that dogs who spend time in the company of other dogs are generally less aggressive. Not surprisingly, some of the less aggressive breeds include Labrador Retrievers and Golden Retrievers.

People who are considering having a dog should familiarize themselves with the background and the needs. of race. ”
