Why does my dog throw up after drinking water? What are the causes?

Updated On September 23rd, 2025

Pet's info: Dog | Beagle | Female | spayed | 40 lbs

I got my lemon beagle almost a year ago. Ever since i got her, she throws up after she drinks water. This happens almost every time she drinks. We switched to filter watet instead of tap. We also got her an anti-choking water that limits the amount they can drink in one lap. With all these changes, she still throws up almost every time she drinks. Is there anything else i can do for her or is this something i will just have to live with?

Hello. I am sorry to hear about Lolly. There are a few other things that you can investigate that could be causing her clinical signs. Myasthenia Gravis is a condition that could be causing regurgitation, so you can discuss this with your vet. Other motility disorders as well could be present, so biopsies of the stomach and small intestines can be performed to check for these motility disorders. If you work these up and cannot find a reason, you can discuss with your vet about trying medications to help with motility including metoclopramide, or cisapride. There is also the possibility of diseases of the pancrease (EPI vs. pancreatitis) so you can have blood-work done to check for this. Also, discuss with your vet about checking for Addison's disease. Full bloodwork and some other specific tests are suggested. Good luck with Lolly.
