Walter Esplin Mason, Dogs of all nations (1915)
“ Weight: 100 lbs.In general form the deerhound should be like a greyhound, but heavier and wiry coated. The head is long and the muzzle tapers decidedly toward the nose. The skull should be flat with no stop. The eyes are dark brown or hazel, and convey a soft look in repose, but a keen far-away expression when the dog is aroused. The ears are set on high and should fall back. A prick ear is bad, and a thick ear hanging flat to the head or heavily coated is an even worse fault. The neck is fairly long and very strong, and should carry sufficient coat to form a mane. ”
