how many of santa's reindeer begin with the letter d

As a magical reindeer, I'm able to fly through the sky with Santa and his sleigh on Christmas Eve. My name is Dasher, one of the nine reindeer that pull Santa's sleigh. The other reindeer are Dancer, Prancer, Vixen, Comet, Cupid, Donner, Blitzen, and of course, the lead reindeer, Rudolph. Together, we make up Santa's team, and we all work together to bring joy and happiness to children around the world on Christmas morning.
