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.

Poor thing! If it came on suddenly, i would be concerned about an allergic reaction to an insect bite or something. Without immediate treatment it will get worse. There are alot of causes of vomiting, but if it was acute, as in possibly after going outside, allergic reaction is possible. I would take her tonthe nearest ER. If it isn't an allergic reaction, they can then treat her symptomatically until your veterinarian can see her tomorrow. If you coose, they can also do a.work up at ER with labwork and xrays if you choose as well.

Hi and thanks for using Petco Pet Education Center, formerly Petcoach! Sorry to hear about Indy. This is what I recommend to all clients- if an abnormal sign persists, worsens, or other signs develop, that is when you should have your pet evaluated. I'm not really worried about the reverse sneezing but if the vomiting persists or worsens, or is accompanied by other signs such as lethargy, diarrhea, decreased appetite, etc then you should have Indy evaluated. If the vomiting has stopped then I think you are ok to just monitor her. Vomiting has many causes including intestinal worms, inflammation, infection, dietary problems (including dietary indiscretion or eating things pets are not supposed to eat, food sensitivities/allergies), ingestion of foreign bodies or exposure to toxins, bacterial overgrowth in the gut, problems in the stomach, intestines, or even problems outside of the intestinal tract/stomach including pancreatitis, kidney/liver problems, metabolic disease (diabetes,etc), endocrine diseases (thyroid or other hormone problems), etc. A thorough history and physical exam with resultant diagnostics such as fecal tests, blood tests, urine tests, and imaging studies such as x-rays/ultrasound can be done to try to determine what is going on. Good luck. I hope this resolves quickly or is already resolved.
