When did dogs become popular?

Dogs have been companions to humans for thousands of years, but their popularity surged significantly during the 19th century, particularly in Europe and North America. The establishment of breed standards and the rise of dog shows contributed to this trend, as people began to appreciate dogs not just as working animals but also as pets. By the mid-20th century, dogs had firmly established themselves as beloved family members across many cultures. Today, they are one of the most popular pets worldwide.
