Someone commented this:
The behaviours you have listed (tail spinning, spinning in a circle, etc.), can be the symptoms of a form of epilepsy in dogs. Therefore there’s another question you should consider adding to your questionnaire: when did this behaviour start in relation to his last vaccine? The Canine Health Concern vaccine survey found that some 73% of epileptic dogs first became epileptic within three months of having a shot, mostly within days or a week or two. Vaccines can cause a condition called encephalitis, which essentially means inflammation of the brain, which can involve lesions throughout the brain and central nervous system. Epilepsy is a symptom of encephalitis, and the obsessive behaviours you are researching are also associated with encephalitis.
Am a but stumped as the research I have done hasnt come up with anything like this?
