Never mind how much it costs. You should not even consider this multilation. Would you like your pinnas clipped? No .of course not. Your dog does not want his doing. Please it is horrendous that you can even consider this. The pinna ,the outside of the ear you see (the lug) is like it is to pick up sound. It is part of his biology. You are not God. Please leave well alone. Love and protect your dog instead.
