What could be wrong if your four-month-old holland lop rabbit has been sneezing for the past month with no other symptoms or changes in personality or habits?
== If there are no other symptoms or changes in personality, it is most likely that nothing is inherently wrong. The most likely issue is that you are either using a litter that has far too much dust, or a hay with the same problem. Have you renovated your living space recently? Dust and chemicals from the event can also trigger such reactions. If the sneezing hasn't subsided within another few weeks or there are *any* personality changes, take the animal to a vet.
