Weimaraners are fast and powerful dogs, but are suitable domestic animals given appropriate training and exercise. These dogs are not as sociable towards strangers as other hunting dogs. 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”.
