Are there really 25 most dangerous dog breeds in the world? The answer is a resounding “no.” The dogs on this list have been misperceived as being one of the most dangerous dog breeds because for one reason or another, but it’s not their fault. However, there are many factors that play a role when assigning a “danger” level to a dog but most critics and researchers disagree as to what these factors are. As predictable as they are, in many ways, dogs are still a mystery.
Consequently, it’s unfair to callously label a dog as dangerous. There are some very dangerous animals on earth, but domesticated dogs are not. Many times, the environment they are in and the humans who train them are the culprits of their behavioral issues.
Nevertheless, it can’t be helped that some dog breeds have more potential to cause serious harm to a person if the dog were to decide to attack. According to the SPCA, aggression is the number one behavioral issue that pet parents seek help with. The SPCA provides a list of indicators that your four-legged best friend may be exhibiting aggressive behavior. This includes:
- Becoming very still and rigid
- Guttural bark that sounds threatening
- Lunging forward or charging at the person with no contact
- Mouthing, as though to move or control the person, without applying significant pressure
- “Muzzle punch” (the dog literally punches the person with her nose)
- Showing teeth
- Snarl (a combination of growling and showing teeth)
- Quick nip that leaves no mark
- Quick bite that tears the skin
- Bite with enough pressure to cause a bruise
- Bite that causes puncture wounds
- Repeated bites in rapid succession
- Bite and shake
