Guard dogs in Britain only bark or bite when there is a danger.
Coz they are lazy. Barking when THERE ALREADY is some danger is useless. Dog`s role has always been to WARN about the danger so that a human could take proper action in time. That`s what Polish dogs do - they still stick to ancient traditions which go back to prehistoric times. British dogs have lost those primordial instincts.
Ignorant dog owners who let their dogs bark all day and night.....
That is called the freedom of bark. Poles are freedom oriented people.
