Yep, we always shower Harry in really quite warm water - he yelps if it's too cold, and backs away!
He actually quite loves the hairdryer (which I've always found quite odd...he's SUCH a boy normally!) and rolls around with glee so it's easy to get to all his 'underparts'...
We normally put his towel in the tumble dryer for 10 minutes so it's lovely + warm + soft for him, for the minute we get him out of the water
