Oh, poor baby Mia......... I definitly know how you feel.......
Mei Mei at 4 months old, would cry really loud and tilt her head to one side. We couldn't pick her up or anything without her yelping and she also wouldn't let my other two dogs come near her.
We took her to the vet and it was a mild bacterial ear infection and he put her on Otomax........cleared it right up and she was back to herself in 2 days, although we had to continue the med for two weeks.
It was just awful to hear her cry.
