When you think of dangerous dog breeds, which animal do you picture: a pit bull or a wiener dog?

According to the results of research published in Applied Animal Behaviour Science, the breed most prone to aggression is the dachshund. New research that involved questioning 6,000 dog owners, found that one in five dachshunds have bitten (or tried to bite) strangers, a similar number have attacked other dogs, and that one in 12 have even snapped at their owners.

Prior research on dog aggression focused solely on dog bite statistics. Using that data, breeds like Pit Bulls, Rottweilers, and Dobermans were thought to pose the most danger. Researchers now feel prior studies were not painting a full picture, as most dog bites (especially those of smaller dogs) go unreported and were not included in the past.

Chihuahuas ranked second on the list of aggressive dogs, while Jack Russell Terriers came in third.

Just like with people, it's not fair to stereotype an entire group based on the actions of a few. But it's also good know some small dogs might not be the ideal choice for children.
