How can I put it? In fact, the earliest discovered border collie is tricolor border collie. I have to say that brown is the basic color, and black and white is the Phnom Penh nose exposed by coffee. If it is brown, it is a nose that evolved from brown. If it is black and white, the color has nothing to do with the quality of the border collie. It all depends on personal preference. First, it depends on the quality of the dog. Second, it depends on the hair. Third, it depends on the distribution of colors. Finally, it depends on the color. Take care of it yourself.
