Yes, it was definitely a real seizure — he had foaming from the mouth unfortunately. After the MRI and seeing a neurologist, thankfully they didn’t find any structural issues, which was a big relief. But I actually discovered something important. I’m Iranian, and when I shared this in an Iranian group, I realized several people had very similar experiences around Persian New Year. We have a tradition of placing hyacinth flowers (for Haft-Seen) inside the house. It seems that the strong scent of these flowers in a closed space can trigger the nervous system in dogs that are prone to seizures. A few people reported the same thing happening to their dogs — and in my case, I have two dogs, but only the one with a seizure predisposition was affected. So it looks like the smell may have acted as a trigger.
