Border Terriers stand from 11 to 16 inches at the shoulder and weigh from 11.5 to 15.5 pounds. The short, wiry coat can be grizzle and tan, blue and tan, wheaten, or red. They’re easy to recognize among other terriers by their unique head shape: “otter head,” as Border Terrier fans say. Another distinguishing trait is that they’re longer in leg than other terriers of their weight. The breed’s admirers cherish the Border Terrier's reputation as a tough, no-nonsense working terrier.
