The first true wolves began to appear at the end of the Blancan North American Stage and the onset of the early Irvingtonian. The start date of the Blancan has not been fully established. There is general agreement that it is between 4.9 and 4.3 mya (million years ago). The often-cited GeoWhen database places it at 4.75 mya. (wikipedia) Sooo, I conclude that wolves have been around for millions of years.
