My 3.5 y/o Great Dane X suddenly started to have sneezing attacks overnight&barely slept.Can't see anything in her nostrils&mouth.Air seems to flow normally on both side.Gums looks good.No asymetry of the face.She's used to have "water like" dripping from her nose from time to time but 1 side seem to have a little bit of slightly thicker but clear mucus.Licks her nose a lot before&after sneezing.I think her submandibular lymph nodes are swollen.Otherwise act & eat normal.Vet or benadryl 1st?

If she was up all night sneezing and it has continued today then she should probably be examined by your vet. I have seen a few dogs that have a piece of grass stuck up behind the soft palate causing the dog to sneeze. Your vet can sedate and do a good exam to figure out why she is sneezing so much. If you wanted to try Benadryl first, it is an OTC medication that can be used for allergies in dogs.
