My 11 year old rat terrier, Dodger, has had vestibular syndrome his whole life (started getting attacks when he was 2 or 3 years old. Recently he had a bigger attack than ever before, and about a month and half later, is still suffering from a head tilt and may have lost a bit of his depth perception (still pretty clumsy). He is back to himself and can go on walks (not hikes) very easily. I know that there has been instances of the head tilt taking up to 6 months to go away, or it never does. I would like to take him for chiropractic adjustments or acupuncture in hopes of helping it speed up! Is chiropractic or acupuncture more likely to be effective in this scenario?
