Spider veins are a group of dilated veins that appear close to the surface of the skin and look like spider webs or tree branches. They are usually red or blue. Although they can develop anywhere, they are most common on the legs and face.
Toy dogs constitute the smallest variant, with a height of 8 inches and weight range of 4 to 6 pounds. A short- and smooth-haired dog, the Rat Terrier has a coat that can sport any of a variety of colors, which include white, red, fawn, black and tan, lemon, brown, blue and white, and red brindle.
The smallest variety was derived from the Smooth Fox Terrier and Chihuahua. The Rat Terrier proved to be one of the best in the rat-baiting pits. One Rat Terrier is reported to have killed over 2,501 rats in a span of only seven hours in a rat infested barn. The Rat Terrier is a hard-working farm hand, able to rid an infested barn of vermin with no problem. The Rat Terrier was officially recognized by the AKC in 2013.
