Just take plenty of fluids.

Verify the Dog's Health: If you can still see the dog or know it survived for two weeks after the bite, you can rest 100% assured that you are safe. ​Physical Examination: Consult a General Physician for a physical check-up. They can check your throat and neurological reflexes to rule out any physical cause for your dizziness. ​Mental Health Support: Since this fear is causing you physical distress 8 months later, speaking to a counselor can help manage this 'Rabies Phobia' (Lyssophobia). ​Vaccination Status: If you never took the vaccine after the bite, you can still take a 'Pre-Exposure' or delayed course for future mental peace, though it isn't medically urgent for an 8-month-old bite from a healthy dog.

Have you taken any vaccination till now? need some information from your side to better understand and give you better advice and management  so ​For a detailed clinical evaluation of your dizziness, a discussion on the '10-day observation' rule, and direct follow-up, you can consult me directly through my profile
