Why is my dog still throwing up after surgery, despite normal tests?

Updated On September 23rd, 2025

Pet's info: Dog | Rottweiler | Male | neutered | 120 lbs

So Roc is my cousin's dog. Last week he went in to have a toenail fixed and had to go under anesthesia. When they took him home the vet gave them pain meds to give him. On the way home he was throwing up. Since then he has been throwing up Non-Stop. He's been back to the vet multiple times and has had blood work done and x-rays and everything is normal. They've also tried giving him the anti-nausea as well as taking him off the pain meds and nothing helps. My cousin is at a loss and no more

Thanks for using Petco Pet Education Center, formerly Petcoach! If xrays and general labwork have been performed already, I would start looking for other possibilities causing this with more advanced diagnostics such as an abdominal ultrasound and GI panel to begin with. Another disease they could investigate is Addison's disease. This would expand the diagnostics to the point of being able to more extensively look into what may be causing this in him. Treatment if any would depend on findings. Good luck!
