My Tan rabbit has had random sneezing fits almost every day for close to two months. I got him from my 4H rabbit project leader in march and she got him from a rabbit show judge that breeds Tans among other breeds. My rabbit has no other symptoms besides sneezing so I do not think it is snuffles. He acts completely normal and even happy besides the sneezing. At times, a white substance comes out of his nose and he is wiping his face with his paws. I took him to my rabbit leader some weeks ago and told her about the sneezing. She checked him out but said he was fine. Could he be allergic to something? I keep him in a room in the middle of our house with a concrete floor with a drain in the middle, and half of the roof is netting, the other half wood.
