Black terrier is a tough dog, resistant to various environmental conditions, not susceptible to diseases, with a balanced temperament, alert but not hyperactive. He is distrustful of strangers, courageous and self-confident. It is perfect for training and learns very quickly. She loves working with her guide, she doesn't like monotony. Works great as a guardian of our belongings. But he is not a dog "for a kennel", he is not suitable for a playpen, he loves being surrounded by his owners, although he is not an imposing dog. Its size does not bother even a small apartment. Usually, he lies down in a quiet place and observes his surroundings. Thanks to his intelligence, he can perfectly assess the degree of threat, reacting only when he decides that the situation requires it.
