I am so sorry about the delay in answering this question. Medhelp emails me when a new question is posted normally. I did not see an email when this question was posted.
Spinal disc disease can cause the problem that you describe. If you have not brought her to a neurologist please do so ASAP. Acupuncture, Steroids, Muscle Relaxers, and other medications may be helpful, but occasionally spinal surgery is necessary. An MRI can help to diagnosis the severity.
If it is not a spinal disease please have your vet check for tick borne diseases, such as Lyme, Ehrlichia, Anaplasmosis, Rocky Mountain Spotted Fever and others with the appropriate blood tests. If she has a high temperature it can help rule out an infectious cause rather than an inflammatory cause or injury.
Hi Krist. I'm so sorry that your little girl is having problems. There are probably many things that could cause your dog to respond like this. I'm glad you took her in to the vet quickly and that you are proceeding with additional care. I would be interested to see what the specialist says, if you feel like posting.
I'm sure this is very scary -they're like our children. Could be just vertigo from an inner ear infection. Best of luck, and I will pray that it's nothing serious. Babs
