Olly is 3 years old and has a lot of allergies like me, we can’t have sawdust, so Olly has baby blankets, I thought it was Snuffles and rushed him to the vet to find that it is allergies, each time he sneezes I say its going to be OK, he does sneeze when he has fresh hay, he sneezes after he has been running around and he does sneeze if I have managed to groom him, he also sneezes if he is nervous, his eyes were red last summer and the vet checked him over and said it was hay fever and there was nothing really he could give him, he does sneeze a lot sometimes and has a lot of mucous on his nose, sometimes he sounds like a Pekingese dog. (Like how those Chinese dogs sound when they bark.) But after he is fine, no more sneezing and he goes back to what he is doing, I don’t know about Snuffles, I’ve never had a rabbit that has had it, but I have noticed if I give Olly a good clean out, a fresh blanket washed in baby washing powder and baby fabric conditioner and then a hay cookie (Like a little bale o hay tightly compressed, he isn’t too bad, but normal hay and he sneezes, one of the Moderators like bam or BB or LittlePuyTail might know more about Snuffles, also what might help your bunny it is an allergy, it might just be a bunny with hay fever, we can get it all tear round, funny enough I had it over Christmas, I’m in England, so it maybe possible you just have a sneezing bunny, but when a bunny sneezes all the dust comes out, like when we sneeze, if it is just that, you’ll get used to it, like me and Olly, I just say. “Oh dear not again.” When he stops I ask if he is better now, I hope it all works out and isn’t anything bad ,
