Poor thing.
She could be allergic to the brand of hay you’re getting. You need to buy from out of state so it doesn’t have sludge in it from the fires. You also should get a air purifier so you can make sure the bunnies lungs stay healthy and clean. Just because you and the vet don’t see discharge doesn’t mean there isn’t any, buns are great groomers so the only way to know if it is an infection is to swab the nose and culture it or put her on antibiotics to see if it helps.

Could be something irritating the nose like a little piece of stuck hay or similar, or could just be allergies to the hay or type of litter that you are using. It wouldn’t surprise me if it’s irritation from the smoke either if there’s a bit of that in the air. Changing the type of grass hay would be my first step, if that doesn’t work you could mist down the hay. I would only mist it down as you put it in the cage and only what they can eat in a day, that way it doesn’t have a chance to go mouldy.

If all else fails, an air purifier is a good option, one with a HEPA filter.

Mellie does this if I use hay that is dusty. It’s almost like bun hayfever. It’s annoying because I can get really good fresh hay from a farmer but it makes her sneeze like crazy, only the fancier expensive hays seem make any difference, and even at that it’s not much. At this point I just have accepted the sneezing. It doesn’t seem to bother her as much as it bothers me! I’ve had her checked a few times and they always just say it’s probably dust from her sticking her long face into piles of hay.

I think if there’s no runny nose or any other symptoms, you needn’t worry much. Mellie has done it since day one and I’ve had her over a year and it hasn’t escalated at all.

PS I did find that keeping the hay outside (in a shed) where theres a breeze seemed to blow some of the dust out? Especially if you let the breeze blow through it as you pull the bale apart. She’s down to about ten sneezes a day now…

No, you need to go to a vet for any bunny medication, they will swab her nose and culture or just put her on a general antibiotic to see if it helps. if there are fires, why would you keep the hay outside where the smoke can get to it and contaminate it? I don’t keep my hay outside for the reason of environmental toxins getting into the hay and contaminating it. The HEPA filter is the best filter for air purifiers since it grabs all the toxins but since you have smoke around you, you’ll probably need to change the filter very often.

Sorry, BH is right- I missed the part about the fires. Adding smoke to dusty hay is definitely not going to help.

So right now that hay is probably contaminated so you need to buy new hay and store it inside the house where clean air is, I know it’s pricy but for the health of your babies, you need to.

Well, it doesn’t mean she doesn’t have an infection, my buns have pasturella and it will flare up and cause sneezing and a runny nose so they go on antibiotics when it flares up.

Do you go to a rabbit savvy vet or a regular vet?

Yes, any hay that is outside will be contaminated, no matter the storage container you use, unfortunately. I know it sucks and hay costs a lot to replace.
Great, the sooner, the better so it doesn’t cause gunk to form in their lungs from breathing in the hay and gunk in their tummy from eating the hay. You can also buy hay from amazon and it will be shipped to you where the hay isn’t contaminated from the smoke.

I really suggest a vet who is cerified in exotics, many regular vets can spay buns but they don’t know how to really treat bunny illnesses, it’s hard being a bun parent haha.

Well I’m allergic to hay so I can’t help too much on the dust factor. Oxbow is good and very little dust, small pet select is good and so is Timothy hay from like tractor supply. I buy mine from rabbit hole but it’s been very dusty the last time I bought in bulk.

I really hope this helps her! You can ask your mom to change your AC air filter more often so it can help push clean air in the house for your family and the buns.

Let us know how she does

Awh yay! I hope she’s feeling better! Huh… did you ask them if they swabbed her nose for a culture? I hope they call you back soon…

Cultures can be unreliable and also they take time to do, as well as the expense. For Wick, we just started antibiotics without a culture to see if symptoms would improve. This is just a consideration, food for thought.

I agree with Wick.

If switching out to new hay and reducing allergens in the environment don’t help, then it doesn’t hurt to try a broad spectrum antibiotic like Baytril to see if it helps. Cultures are not very reliable since bacteria that isn’t causing the symptoms will grow too. Most vets only do them if a broad spectrum antibiotic fails. Rabbits can have a URI and the only symptom is sneezing. There are other possibilities to consider if an antibiotic doesn’t help.
