Someone pretending to knowledge & authority trotting out the tired idea that some breeds of dog are inherently more dangerous than others. There are no "dangerous dog breeds," just dangerous dog owners. (Inbreeding & maltreatment can produce psychosis in dogs, which can make individual animals dangerous.) Every generalization about a breed in the blog entry is belied by actual experience. I know a pug, for example, who bosses around the neighbor's 140 lb pit bull. Some dogs are larger and stronger than others and especially when badly raised / trained, those dogs can do real damage to other dogs or humans when provoked.
