How I am already sayed, my name is Nio. My owner is Dadka and my complice is Marek. They called me Nini, Ni, Ninucha, Nino, Trdes ( something as muff), Čierny (Black) and somehow else. We a lot of travel together, resort to moutains, swim, run next to bicycle....I often hear that I am untired. Do you know, what they think by this?
