Most Aggressive Dogs

The introduction and use of the C-Barq has provided an interesting insight into breed specific characteristics. Providing insights related to stranger directed aggression. It has also provided insight into breed specific characteristics related to unfamiliar dog directed aggression. The Canine Behavioral Assessment and Research Questionnaire identifies the most aggressive dogs by breed. Information provided by respondents determines the identification of these breeds. A recent study “Breed Differences in Canine Aggression” took data from the C-Barq. The study looked at the most aggressive dogs. It identified the most aggressive dog breeds based on the information. The study separated the breeds by stranger directed and dog directed aggression. The study identified those breeds who more frequently exhibited these aggressive behaviors. It compared these identified breeds to the other breeds represented in the study. The research doesn’t include all breeds though. Included in the results are the:

  • Airedale Terrier

The data included information from breed club participants. It also included information from individual dog owners. It included both male and female, neutered and intact dogs.

The C-Barq is unique in its process for assessing the most aggressive dogs. It asks for information about the evaluated dog’s response to certain situations in the recent past. The C-Barq formed the questions in such a way as to decrease breed stereotypes and biases. Answers depended on the respondent’s subjectivity so there may be some distortion of the results.

According to the study the top 10 most aggressive dogs that have a tendency toward stranger directed aggression are:

  • Dachshund
  • Chihuahua
  • Doberman Pinscher
  • Australian Shepherd
  • Australian Cattle Dog
  • Bichon Frise
  • German Shepherd
  • Jack Russell Terrier
  • English Springer Spaniel
  • Havanese

The top 10 most aggressive dogs that have a tendency toward dog directed aggression are:

  • Akita
  • Dachshund
  • Jack Russell Terrier
  • Pit Bull
  • Chihuahua
  • English Springer Spaniel
  • Australian Cattle Dog
  • German Shepherd
  • Boxer
  • Australian Shepherd

The study does caution that it is not a good idea to make predictions about a given dog’s tendency toward aggressive behavior based only on its breed. Not basing an opinion on a given dog’s tendency toward aggressive behavior based only on its breed does seem to be good advice. Upbringing and environment play a large role in which behaviors a dog chooses to display in any given situation. The dog’s breed can give a person a first impression about an unknown dog though. The dog’s behavior in the moment and breed is sometimes the only information a bike rider or runner has to form an opinion.

Here is a note about Pit Bulls. The study found that the breed ranked slightly higher than average in most aggressive dogs with regard to stranger directed aggression. The Pit Bulls’ ranking slightly higher than average does contrast with public opinion. Public opinion being that the Pit Bull breed is one of the most dangerous breeds. The study makes note however that this dog breed is of large size and considerable strength. The damage done by one incident involving a pit bull would be severe as opposed to one incident inflicted by a small dog. Evidence did support the belief that the Pit Bull is one of the most aggressive dogs with respect to dog directed aggression. Evidence supported the belief that breeding for dog fighting had occurred with this breed. The occurrence of reported bites directed at other dogs was around 22%.

It is not very often that you will run into a purebred dog on your ride or walk and breed is not always the best predictor of a dog’s reaction in any case. Upbringing and environment greatly influence a dog’s reaction in any given situation. Breed identity and the dog’s behavior at that moment may be all you have to work with though.
