38 Dog Breeds That Require Extra Caution and Understanding

2. Pit Bull

This breed results from combining the energy and agility of a terrier with the strength and build of a bulldog. Some experts believe the increase in pit bull incidents is due to the breed's growing popularity. Pit bulls were bred for fighting and are often mistreated or improperly contained. With appropriate care, though, this intelligent breed can be quite social and playful. PETA has commented on serious pit bull incidents, noting that pit bulls often suffer widespread, ongoing abuse and neglect. This may explain why this breed is frequently involved in serious injuries or fatalities.
