Q. My dog keeps shaking his head at night and is very anxious acting? We've cleaned his ears and putting ear drops in hasn't helped?
A. It sounds like ear canal infection. I am not sure if you used ear drops to clean ears (they do not contain antibiotics) or ear drops from your vets to treat ear infection. In case you used ear cleaner only you should take your dog to your vets to get antibiotics. If you are using antibiotics drops and there is no improvement your vet may recommend taking a swab from the ear to check what bacteria, fungus or parasite is responsible for the infection and then pick the most effective medication.
