Our Golden Hunter got Meningitis at around 10 months old.
It did hit pretty fast. We came home one day and he was just acting REALLY lethargic and would only move for food. We just kept an eye on him but his heart was slowing noticeably so we took him to a 24hr vet. When he got out of the car he was up and moving so we thought it was something small, the vet said he seemed ok so he just came home. Our regular vet we saw thought it was a blockage in his stomach and was going to operate. Luckily we took him to a specialist at the local uni who diagnosed it. Even then it took them a while to diagnose, I dont think anyone had direct experience with it.
