Golden Lab

Question
My golden lab has been shaking his head quite frequently.  He isn't whining or grouchy or anything, but I checked the ear and it looks like there is dried blood in it.  I bought some ear cleaner (ear wash and ear dry it was called) but it hasn't seemed to help too much.  Any ideas?

Answer
IF YOU ARE SEEING BLOOD IN THE EAR, THAT SHOULD TIP YOU OFF THAT THIS IS BEYOND YOUR SKILL LEVEL.  PLEASE TAKE THE DOG TO THE VET TO CHECK AND SEE IF THE EARDRUM IS RUPTURED, IF THERE IS AN ULCER IN THE EAR, OR IF THERE IS A BLEEDING TUMOR. JUST PUTTING IN AN EAR CLEANER MAY DO MORE HARM IF THE EARDRUM IS RUPTURED.
