Help! Bunny snorting when breathing medium-heavy

[EmmWarr]

My bunny started snorting when he breathed a couple months ago and I am quite worried.. I have a lot of dust around my yard (I let him run aroun) could that be why? He otherwise seems healthy and happy.. not sre but may be drinking less water.. anything I can do to clear his sinuses? Do you know the price of s check up and or treatment at the vet? (In BC) thanks so much.. I am tight on money ATM so hoping to be able to help him myself but definitely willing to go to the vet if necessary

Is there any discharge from his nose? Does he open his nostrils wide or lift his head / open his mouth to breath? Is there any discharge from the eyes? If the answer to all of these questions is no, I would stop letting him in the yard for a couple of days to see if it changes anything. Let the rabbit run around inside the house to rule out the dust problem as a cause. If the answer to one of those questions is yes, I think you need to see a vet - discharge indicates an infection and you need antibiotics.
