Customer Question

I have a 9 yr old intact female Australian Terrier who just had her blood work done and all came out fine. She is on day 12 of estrus and is sitting on her haunches, turning her head back and forth, eyes dilated. She notmally,goes, everywhere with us. Can sense no pain in her spine or legs, anywhere. She started on 6 c of Arnica Montana and 150 mg of ASU 3 DAYS AGO. Eating regularly. What do you think?

Elaine, my initial thoughts are that her turning her head in that manner in conjunction with mydriatic (wide open pupils) indicates a newly blind dog or, instead, a postural repetitive myoclonus - a type of head tremor in which there is an episodic high-frequency "yes" or "no" movement of the head often confused with focal seizures. My initial exam would be a thorough look at the fundus (back) of her eyes for pathologic changes in her retinas which may or may not be present. A lesion involving structures outside of her eye (optic chiasma, e.g.) and in her brain can also cause blindness. Blood work isn't expected to be helpful in diagnosing these dogs. A thorough neurologic exam which might include MRI is indicated.

Please respond with further questions or concerns if you wish.
