The breed is not heavy for its height, and males normally weigh roughly 70-85 pounds. Females are generally between 55-70 lbs(25-32kgs). A Weimaraner carries its weight proudly and gives the appearance of a muscular, athletic dog.
Temperament:
Weimaraners are fast and powerful dogs, but are also suitable home animals given appropriate training & exercise. These dogs are not as sociable towards strangers as other hunting dogs such as Labradors and Golden Retrievers. Weimaraners are very protective of their family and can be very territorial. They can be aloof to strangers, and must be thoroughly socialized when young to prevent aggression. They are also highly intelligent, sensitive and problem-solving animals, which earned them an epithet "dog with a human brain". They are ranked 21st in Stanley Coren's The Intelligence of Dogs, being of excellent working/obedience intelligence.
From adolescence, a Weimaraner requires extensive exercise in keeping with an energetic hunting dog breed and prized for their physical endurance and stamina. No walk is too far, and they will appreciate games and play in addition. An active owner is more likely to provide the vigorous exercising, games, or running that this breed absolutely requires.
Weimaraners are high-strung and often wear out their owners, requiring appropriate training to learn how to calm them and to help them learn to control their behavior. Owners need patience and consistent, firm (yet kind) training, as this breed is particularly rambunctious during the first year and a half of its life. This breed is known for having a penchant for stealing food from table and counter tops whenever given the chance. Like many breeds, untrained and unconfined young dogs often create their own fun when left alone, such as chewing house quarters and furniture. Thus, many that are abandoned have behavioural issues as a result of isolation and inferior exercise.
Weimaraners are often kind to children, but they may not be appropriate for smaller children due to their tendency to knock a child down in the course of play. The breed is so full of energy that early training to sit (through positive reinforcement) is critical to prevent jumping in the future, as these strong dogs may knock over elderly people or children by accident.
It should never be forgotten that the Weimaraner is a hunting dog and therefore has a strong, instinctive prey drive. Weimaraners will sometimes tolerate cats, as long as they are introduced to the cats as puppies, but many will chase and frequently kill almost any small animal that enters their garden or backyard. In rural areas, most Weimaraners will not hesitate to chase deer or sheep. However, with good training, these instincts can be curtailed to some degree. A properly trained Weimaraner is a wonderful companion that will never leave its master's side.
The Weimaraner is a deep-chested dog, which makes them a breed which is high on the list of dogs affected by bloat or gastric torsion. This is a very serious condition that causes a painful rapid death when left untreated.
It occurs when the stomach twists itself, thereby pinching off blood vessels and the routes of food traveling in or out. Symptoms include a dog showing signs of distress, discomfort, no bowel movement or sounds, and a swollen stomach.
Immediate medical attention is imperative when bloat occurs and surgery is the only option if it is caught early enough. One way to help prevent bloat is to spread out the Weimaraner's feedings to at least twice daily and to avoid any vigorous exercise right after feedings.
It is also recommended that the dog's feeding dish NOT be placed on a raised platform, to stop the dog from gobbling the food too quickly and to keep air from entering the stomach. There are special bowls made for gulping dogs, as well. Weimaraner owners might never see this problem in their dogs but should be familiar with the ailment and keep emergency vet numbers handy.
According to the Orthopedic Foundation for Animals, Weimaraners suffer from low rates of dysplasia. The breed is ranked 102nd of 153 total breeds and has a very high test rate and a very high percentage of excellent rating among those dogs tested. It is generally recommended to acquire Weimeraners only from breeders who have their dogs' hips tested using OFA or PennHIP methods.
