Great post Maureen! That's too bad. My BunBun started sneezing here and there, but when he'd sneeze, it'd be a bunch in rapid succession and then an almost gag. He had the eye thing going on at the time too, which I was given eye drops for. The vet was treating at that time for cherry eye, or prolapse of the third eyelid. Well, that really never went away. After a while, he had started breathing heavy at times. The first time I noticed this, we rushed to the vet. This time I was given baytril for a possible upper respitory. The heavy breathing continued on and off. The next time I took him to a different vet as he was closer. He took xrays and found that he hadCongestive Heart Failure, a very enlarged heart. There is no cure for this, only medication to keep it under control for the rest of the bun's life. He then was put on Enilapril and Lasix. This helped, but caused poopy butt and a very gurgly tummy towards the end. I still think to this day (and probably always will) that the eye problem was related to the pressure in his chest. Maybe not, but, who knows. This just goes to show that sneezing needs to be monitored.
My two now sneeze once in a while, not often, and they only sneeze when they're grooming themselves, I chalk it up to them getting hairs in their noses. There's no discharge at all, just wet nose. So I know this is nothing now, but it will always be monitored.
