Who has dog doesn't bark. (Qui a chien - N'aboie pas)

Don't raise your stick and the dog won't bark at you.

Don't BARK over the phone, if you ain't gonna BITE in person...

Jealousy is a dog's bark which attracts thieves.

One dog barks at something and a hundred bark at his sound

Muzzle a dog and he will bark out of the other end.
