In what conditions a comma should be used before a conjunction?
I read somewhere that in compound sentences, when a dependent and an independent clause are connected it would be proper to use a comma before a conjunction. Is it true?
I think Lewis's answer may have confused everyone. You asked about an independent clause attached to a dependent clause. That is not a compound sentence and no comma is required with the conjunction.
Lewis responded with examples of two independent clauses. As Lewis demonstrates, to join two independent clauses, a comma + conjunction is required.
Sorry to jump in, but a casual reader may be confused by the "subject disagreement" between question and answer.

In fact, the comma is not always needed when two independent clauses are joined by "and" -- this only applies to "and," not to other conjuctions.
The reason a comma is required (you MUST use a comma) in this sentence is to prevent possible misreading.
"The boy threw the ball and the dog" . . . huh! . . . oh, and the dog "chased after it."
