My dog started reverse sneezing, now she's shaking, sluggish and her eyes are very red. What could be wrong with her?

It sounds as though she may have some [environmental allergies](https://www.petcoach.co/article/food-allergies-vs-environmental-allergies-whats-the-difference/). [Allergies](https://www.petcoach.co/dog/condition/canine-allergies/) can stimulate the release of histamines which can increase gastric acid production the stomach which may explain the vomiting. If she is lethargic, anorexic, or shaking, I would bring her in for a physical exam. You can discuss allergy testing, hydrolyzed diets and antihistamine use with your veterinarian during the exam.
