But from prehistoric times, through thousands of years of selectively breeding the smallest with the smallest and the tallest with the tallest, today we have Brandy, a Chihuahua from Largo, Florida and Gibson, a Great Dane from Grass Valley, California—the world’s smallest and tallest dogs.
Brandy lives with Paulette Keller and three other dogs. She was the runt of a litter of five Chihuahuas. As an adult she weighs 1 pound, 13 ounces and is 6 inches from the base of the neck to the base of the tail. Brandy is small enough to curl up on a dollar bill, but she sleeps and travels in a sheepskin-lined purse.
Three-year-old Gibson belongs to Sandy Hall, a breeder of Great Danes. Gibson stands 7 feet 2 inches on his hind legs, which is taller than most players in the NBA. He is 3 feet 6 inches at the shoulder and weighs 175 pounds. Gibson eats 10 cups of dog food a day plus pizza, linguine with clam sauce and other daily specials. He usually sleeps on Sandy’s bed, which we imagine to be rather large.
