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 breed has been used as a guard, ratter, herder and watchdog. The Miniature was developed to have the same qualities as the Standard Bull Terrier but with a more manageable size. The Standard Bull Terrier was first recognized by the AKC in 1885 and the Miniature Bull Terrier in 1991. While the AKC sees the Standard Bull Terrier and the Miniature Bull Terrier as separate breeds, the standard requirements are the same except for size.
