Description of Lastochka:
Lastochka is a great dog - fast, with a great mental balance (never chewed anything, never whined in a cage, never got overexcited).
In everyday life she is completely unnoticeable, but in sports she is a rocket. She has a crazy drive, complete reliability in work, which she inherited from her father Zeus.  Lastochka is not aggressive to anyting. She is a genius at work, very simple in everyday life and very friendly.
No reaction for noises or shots.
