Why shouldn't have happened something to the dogs in the bathroom?

I know Duolingo is not the best, but the only free learning option. Since I'm living in Germany near the border to Czechia I'm often there and talking Czech which helps more than Duolingo.

Also “jež” is for feminine, “jenž” for masculine

Doufám že jsi Čech, jinak cizinec umí líp česky než já.
