The Border Collie and the Australian Shepherd are very similar. They have only a few differences. First, the Border Collie and the Australian Shepherd are known for being dogs that are used on farms. They help to herd the other animals. They also look very much the same.
However, there are a few differences between these two dogs that could be twins. The Border collie is from the United Kingdom, whereas the Australian Shepherd is not. The Border Collie males are slightly smaller than the Australian Shepherd and weight quite a bit less. The Border collie works well with a family, especially children, but the Australian Shepherd may not be because of their uncertainty with these animals around children and other pets.
