My dog is suddenly throwing up, shaking, and won't eat. What's wrong?

Updated On September 23rd, 2025

Hello, my dog Sophie has been fine all day but then all of a sudden she started throwing up and acting really shaken. She’s thrown up 4 times in the past 2 hours and I’ve given her Pepcid and some of her meds she was prescribed for vomiting but she won’t stop shaking.. she’s drinking water but has no appetite.

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.
