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.
An American breed, Rat Terriers are known to reach speeds of up to 27 mph. As the name suggests, they were originally used by British migrants in rat-baiting. However, due to their quick agility they soon became used for vermin control, hunting animals like squirrels and hares, particularly in American farms.
