Aggressive & Dangerous Dog Breeds

Before discussing the aggressive breeds, we need to emphasize that the owner is responsible in nearly all cases. While some breeds might look more dangerous than others , bad training, socialization and inappropriate rewards for problem behavior will all give dogs the structure they do not want to be well-balanced. Lack of leadership and lack of physical stimulation means that any well-intentioned dog can end up displaying aggressive behavior.

The breeds listed below are breeds that have either been known to “bite” or are in the top 10 of all breeds in caused fatalities from 2005 to 2017. Causation does not necessarily imply representation. Many bad dog owners end up with breeds who are strong-willed. This could lead to behavioral problems and unwelcome aggression. Love Your Dog believes that every dog can be trained correctly and have a fulfilling life. The bottom line is that some breeds are known for having a bad reputation. These reputations were passed down through the generations. Let’s look at the 20 most likely breeds to be labeled as “dangerous” or “aggressive.”

Chihuahua

The tiny Chihuahua might not be as tall as some of the other dogs on this list but that should not mean you underestimate their fierceness. Weighing, on average, under 10 pounds this lap dog can sometimes be treated more as an accessory than an animal. These lap dogs are usually built with an Apple head or a Deer head ,. The head type does not make them less or more aggressive.

They can become territorial if they are not taught boundaries and given obedience training. Chihuahuas will snap at unwanted visitors and bite them. This is most likely an act of self-preservation. Even though you’re as small as a Chihuahua you have to be able to defend yourself and stand your ground. This instinct can be exacerbated by owners who spoil the breed, which can lead to aggression.

The Chihuahua is likely to inflict more bites per breed than any other breed. It has nothing to do with their genes. This is due to the fact many small dog owners fail to correct their dogs’ problem behaviors early. Chihuahua aggression is often ignored or encouraged by owners because they think it’s cute. This can lead to a small dog who is as aggressive as a Pitbull or Rottweiler.

Pitbull Terrier

Pitbull Terriers are notorious for their bad reputation. They were once considered the “nanny dog” by many families in the United States during the mid-1900s after World War II. They were great family protectors and fought alongside soldiers in World War II.

There are actually 4 different types of dogs that fall into the Pitbull breed family, which gives more opportunity for something bad to be credited back to this misunderstood breed. It’s not uncommon that many mixed Pitbull breeds are classified as purebred Pitbulls after an attack. They can be the most sweet dogs you will ever meet, despite insurance companies having issues with them. Unfortunately, plenty of bad actors have given them a poor reputation through teaching bad behavior habits and dogfighting.
