I was just curious what percentage of older Basenjis have had bouts with Canine Vestibular Syndrome. My vet was never able to make a firm diagnosis (he hadn't heard of it before) but both Cassi and Alex had occurrences around 13+ years of age. Alex had a second occurrence a year later, and has never completely recovered. When it first happened, we thought the dog might have had a stroke. It wasn't until a friend who's dog had had similar symptoms told me about their dog's diagnosis the I started researching it.
If you're unfamiliar with the condition, here are a few links with some basic info:
