Luckily, I always put a "muffler" around my puppy client's hears so that any noise from the blow dryer is muffled. On top of that, I purchased a blow dryer designed to be so much quieter than the other high velocity dryers available for the industry. I also used a small towel to keep the other parts of his body from getting hit by the air. I figure that I wouldn't want other parts to get hit with air causing him to get cold.
Frosty did really well when I was drying is body. When it was time for the face, I decided to use my own ionic hair dryer on the lowest setting. I first combed and did a flash dry and combed again followed with a flash dry until Frosty seemed okay with the hold thing. I guess the secret to the whole blow drying thing is to avoid getting air inside of their ear and also in their eyes and nose. Oh and being gentle helps tremendously too !
