Among the types of personal injuries, dog bites often sting the worst — emotionally and physically. Victims often feel bad about reporting dog attack injuries. Unfortunately, failing to hold bad owners responsible only perpetuates the problem.

All told, nearly 5 million people suffer a dog attack in the U.S. each year and almost a million need medical treatment, according to CDC data.

Some key points to know about dog attacks:

• Any breed can be involved in an attack. Even lovable breeds and small dogs can inflict bloody injuries.

• People are often to blame. Owners have a responsibility to train their pets, especially if they own a breed more likely to bite.

• You can take self-defense classes from St. Louis martial arts centers to learn how to prevent and diffuse dog attacks.

• Infants, toddlers, and the elderly are the most likely to be hospitalized.

• Dog bites often lead to massive medical needs: in 2012, over 27,000 people needed reconstructive surgery.

After a dog attack, here’s what to do:

• Find out the dog owner’s name and contact info.

• Take photographs of the scene and injuries.

• Seek medical attention as needed.

• Contact a dog attack investigator to examine the case.

When dogs bite, people must be held responsible for the pain and medical bills that follow. Talk to an attorney about a St. Louis dog attack lawsuit for expert guidance in the matter.
