Traduko - Latina lingvo-Sveda - Canis timidus vehementius latrat quam mordet

Lilian,
meningen/betydelsen är helt förståelig, men jag tror att denna fras brukar översättas: "En rädd hund skäller värre än den bits."

Yes, Pia, I know that it's a well-known saying in every language, therefore each one has an usual way to put that. Swedish wouldn't be different. In English the saying is usually heard as :
"Sb's bark is worse than their bite"
I just translated literally because it came from Latin. But if you think the saying has to be passed on with it usual structure in Swedish, it's fine to me.

Ok
So we can keep your translation as it is (since this is "meaning only" ) and then I put the more "common" Swedish one in the notes.
