Found someting interesting about dogs Ears.

Hey I was on one of the forums I am associated with and I came across some interesting news about someones dog. There dog was shacking its head vigorously and they tried to clean it thinking it was just ear mites. The cleaning didn't work so they took the dog to the vet and to find out what happen when they where cleaing the ear one time a discharge came out. That discharge winded up to be the feces of a tick that had layed eggs on the dogs eardrum and that was the cause of the dog shacking its head so much. Heres the link if you want to read more about it and there is alos some more interesting things in the forum also:
