I have a doberman and i need to get his ears cropped and need to know where to go .?

He is 9 weeks old sat. and he is 18lbs, 14.5 inches tall. He has his tail chopped allready and i dont care what yall have to say about anything lke why do that or its bad and crap because when you have there ears cropped they can pinpoint up to 5 degrees where the sound is coming from. if you dont know nothing dont say nothing. please look up something on this before you say something i have studied dobermans and i do know what i am talking about
