My 7 month old Holland Lop has sneezed a few times over the past week , not frequently - but twice ( 3 days apart ) he sneezed out a little white milky liquid - the size of a dress shirt button ... a thin mucous consistency . I am wondering if this is the sign of an infection ...or can this be a result of a buildup of hay dust . His nose is otherwise dry , he acts fine and does not seem lethargic . I have not spoken to his vet yet ...Grandma is watching him for a few days and cannot drive to take h to the vet or pickup any meds. i will def have him seen when get back -but wondering what I might be dealing with.
