Hi and thanks for your question.

It's a little bit strange to see a dog suddenly have sneezing fits like this. Although I can't say for sure without seeing Lilly, what you are describing sounds more typical of a mild virus rather than allergies.

Dogs with allergies will usually have itchy skin (usually feet, ears and bum) or diarrhea. We don't commonly see sneezing as a sign of allergies in dogs.

However, there is no harm in giving her benadryl to try. The dose for a 6 lb dog is 1/4 tablet of 25mg benadryl 3 times daily. Keep in mind though that if this was due to allergies (which I don't think it is) most dogs need stronger medication such as steroids in order to get better.

Another possibility is if she has something stuck up her nose. If the sneezing is getting worse, or if you are noticing a green or yellow discharge from one nostril then this could be what is happening. If this happens you'll need to see your vet.

Does she have bad teeth? At 1 year old she should not, but chihuahuas sometimes can have bad dental problems even when young. A problem with an upper tooth can cause sneezing as well.

Another possibility is nasal mites. If the sneezing continues your vet may choose to try treatment with Revolution (a heartworm medicine) if they suspect this.

My guess though is that it is a mild virus and she will be find within a day or two!
