This post objectively examines dog breeds that statistically cause the most human injuries and fatalities. The goal is to educate current or potential dog owners on how to properly train, socialize and care for their pets. With the right precautions, even breeds with higher incidents of aggression can become valued family members.
Dogs have been our loyal companions for thousands of years. They provide love, comfort and protection. However, some breeds are known for aggressive tendencies that need proper training and socialization to prevent unfortunate incidents.
What Causes Dog Aggression?
Dog aggression stems from a combination of genetic factors and environment/training. Some breeds have been selectively bred for certain traits like guarding ability that require proper handling.
Dogs can also develop aggressive tendencies through:
- Lack of socialization
- Abuse or neglect
- Fear
- Protecting territory
- Poor health
Aggression is a natural instinct in dogs, but behavioral problems are preventable with the right care and training.
Evaluating Dog Bite Statistics
There are over 90 million pet dogs in the U.S. When looking at dog bite statistics, it’s important to understand what the numbers mean.
- Fatalities are rare. About 35-40 people are killed by dogs annually in the U.S.
- Any size or breed is capable of biting. Small dogs account for 20% of reported bites.
- Unneutered males are most likely to bite.
- Children are most at risk of fatalities.
- Certain breeds are overrepresented in incidents due to popularity and breeding history.
- Breed identification in reports is often inaccurate.
Dog bites can happen for many reasons. While statistics on high-risk breeds provide useful information, they don’t tell the whole story.
