Behold the Grey Phantom: the Weimaraner belongs to the sports dogs’ aristocracy, a German creation for large game. Its amber color eyes, peculiar grey coat and its fine sense of smell has made it gain lasting popularity. 
The Weimaraner is unique in many aspects: it distinctive mouse grey to silver grey color, its amber colored eyes from dark to light shades and with intelligent expression, its webbed-feet, its aristocratic hunter stance. It stands between 63 to 68 cm, the female 5 cm less and weighs from 30 to 40 kg, the female 5 kg less. It is well balanced, and is the live image of grace, speed and resistance - preferably wrapped in good, working dog muscles - . Proportionate head, in harmony with the body size and face; in the male it is wider than the female, with the stop moderate and occipital from slightly to moderately marked. Quite deep and straight lips; grey nose; scissor closing; long ears almost to the corner of the muzzle; high inserted and narrow, when the dog is attentive, folding them slightly forward. The back is moderately lenghthed, strong; the chest deep, the shoulders well sloped backwards. The forelegs straight, elbows not tucked in or out; firm and compact feet, dark or light grey colored nails; parallel hindquarters, well angled, straight hocks, capable of a free and effortless coordination. In the US, the coat can only be short, smooth and straight, always unicolor, admitting, a small white spot at the chest. The FCI and the KC admit short hair and long haired varieties, this of 2.5/5 and 5 cm in length. The tail robust and well covered in hair. It hangs when at ease; if the dog is attentive or active, it keeps it in horizontal position or slightly raised. For Americans, the tail should be docked to 15 cm; otherwise it is penalized in shows.
In American shows, the long haired Weimaraner disqualified; in Europe these silky haired phantoms are seen more frequently. Training the Weimaraner requires an experienced, patient person, with plenty of time to devote to the dog. 
Compliant and pending of what is expected from it, the Weimaraner is excellent as a company animal, as well as a hunting dog. It’s a very together dog, who loves the family life; it cannot live in a breeder. It is a clever dog, very apt for obedience and field work, and its natural collecting and trail talent display its instinct superiority. Even so, the Weimaraner has its character and can be difficult to train; the owner should know how to channel its wit, sine otherwise it can be bold. It often hunts alone, and doesn’t get along with strange dongs.
Some trainers say that the Weimaraner is a stubborn dog. Therefore, begin teaching the puppy soon to discourage it from biting things, soiling the carpet, and other bad habits. The puppy is set in ideas, but also wants to please. 
At birth it weighs a good 280 to 450 g. The dewclaws and tail are docked during the first week, perhaps later. At birth the color is unusual, a grayish base with dark stripes along the body. There are blue puppies, but they are disqualified for show. There are also white spots, which are undesirable. A few small white spots may disappear with growth. The Weimaraner has soft skin, and precautions are needed to avoid injuries. It is also known for its ugly walk, which is improved by making it trot. This irregular pace can become more serious with age.
The Weimaraner is a resistant dog that stands out in hunting and work tests. It is an easy to care for partner that demands little care but plenty of exercise. It needs an outlet for its hunting instinct. The Weimaraner suffers the common canine diseases, including hip dysplasia, entropion, third eyelid disorders (nictitating membrane) and chriptorchidism; all of it without too many frequency in the breed. Other two unusual problems affecting the breed are mutant color dermatitis and vertebral dysraphism. The first is a skin disease (dermatitis) that affects blue specimens. Breeders observe that the anomaly is not very serious or as common as in other breeds. The latter, not frequent either, is a serious but not mortal anomaly, which causes abnormal movement (hoping) and shrunken posture. It can be diagnoses but has no treatment. Hemophilia A and malign mouth cancer has been reported in the breed.
Choose a puppy that is not fearful and is kind. The mother should also have these qualities. 
If you work all day or live in a flat, don’t torture a Weimaraner, and choose a different breed.
