What is a "sheepdog"?

A sheepdog is a type of working dog that is bred for the purpose of herding sheep, cattle, or other livestock. They are highly intelligent, trainable, and have a natural instinct to herd and protect livestock, making them valuable assets to farmers and ranchers. Some of the most well-known sheepdog breeds include the Border Collie, Australian Shepherd, and Old English Sheepdog, although there are many other breeds that are also used for herding. Sheepdogs are often trained from a young age to learn basic commands and develop the skills necessary to successfully herd livestock.
