It has taken me about 2 years to get Dobe used to me washing his face and this summer is the first time that he has been completely comfortable with it. What I did was take any kind of spray nozzle off the end of the hose, turn the water on very lightly (more than a trickle but not full blast either). I started at a place on his neck where he was comfortable and rubbed him with the end of the hose in my hand. I slowly worked my way closer and closer to his head and finally got to his jaw. Then I worked under his eye and up onto his forehead. Stay away from their ears when you are first doing it. Past that, just keep working on it until they are comfortable with water being run over their whole head. Make sure to NEVER get any in their ears though, that will make them shy from the water for a really long time.
