Ear? (medical)

[MollyGirl]

I have noticed the past couple of days the Phoebe has been shaking her head and it is not something she has done in the past her ears look fine, no discharge, not smelly, just pink and clean.  I was wondering if I should take her in, if she maybe has the beginning of a ear infection?
OR maybe all her barking has finally taken its toll on her ears too. HEHE!
