Use a comma to separate the "wagging tail" from the rest of the sentence. ("Wagging Tail" is not an official grammatical term, but an informal one to describe the variety of "appendenges" at the ends of sentences. These may include phrases, parenthetical expressions, and occasionally dependent clauses.)
