They are loyal to their masters, spirited and alert, with high energy. Intelligent, lively and brave, it is a big dog in a little dog's body. The Miniature Pinscher is moderately protective. Some can be very aggressive with other dogs, but they are generally good with other pets and children provided the children do not pester. They are rather suspicious towards strangers, but their behavior depends entirely upon how they were brought up as young pups. Don't spoil this breed too much or the dog may become a tyrant. The Miniature Pinscher can learn extremely well and wants very much to do so. It is certainly beneficial for its socialization to take the dog to puppy courses where it can meet other dogs and people.
