Help with a Latin translation for a popular Vespasian quote

[Naja]

Vespasian was reported to have said "I will not kill a dog that barks" in reference to one of his political opponents. I really like that quote!

Does anyone know what the classical Latin for that would be?

[Morticia Iunia Bruti]

Ego non canem occidam, qui me latrat.

[Aermanner]

Non canem latrantem occido.

There are a couple of ways to express this, depending on emphasis and meaning. The above is a simple translation of your english quote. You can leave out canem, because latrans can be used for a barking dog.

[Alastor]

I have seen this in Greek and then translated to Latin in this form:

ἐγὼ δὲ κύνα ὑλακτσοῦντα οὐ φονεύω.
Ego vero canem latrantem non occido.

So, I guess I will go with:
Canem latrantem non occido

[Muizer]

"Canem non occidam qui vehementius latrat" is my best shot at turning an after-the-fact comment in Suetonius into a motto: "I will not kill a dog that barks too loud".

Based off the original text by Suetonius

"Unum ex familiaribus suis, acerrimum loquentem adversum se, subtraxit a suis laqueis ac vita donavit, addens hanc gratiam, quod canem non occidisset, qui vehementius latrabat."
