American traditional dog tattoos, more commonly known as “flash” tattoos, have a long and interesting history. They can be traced back to the 1800s when sailors and military personnel were getting tattoos in foreign ports. The tattoos were often simple, but they were a way to show one’s loyalty and bravery. As time passed, the tattoos became more and more popular, and by the early 20th century, they were a common sight. Over the years, the designs have evolved, but the basic idea of the tattoo has stayed the same.
