What we know about dogs historically is limited, however, the Romans used dogs as “weapons”, as guards, on patrols but also kept them as pets, so they were always known as creatures in the service of humans.
This was until the 19th century when in America the Bloodhound became the first dog to get bad press.
They were partly criticized because they were used to catch escaped slaves.
Even the Dobermans who came to the United Kingdom and America from Germany in the early 1900s and gained a reputation as trustworthy guard dogs, their image was completely changed in World War II, as many dogs were photographed with Nazi officers in concentration camps.
After the war, they became less and less popular and were portrayed in movies and in the media as “demon dogs” despite their intelligence and loyalty to their owner.
The Rottweilers suffered a similar fate, they were favorites to guard properties.
While Pit Bulldogs were originally trained in the 1800s to use in blood sports and dogfighting, in the 1960s a different urban trend began to develop in America, drug gangs began training and using pit bulls as guard dogs and status symbols.
Before the 1980s there were far fewer deaths reported from dog attacks, but that decade was the era that created precisely the public perception that pit bull breeds were dangerous.
