My dog vomits after drinking water. Is it a blockage or behavior?

Updated on September 23, 2025

Pet's info: Dog | Mixed Breed Medium (23 - 60lb) | Female | spayed | 44 lbs

My dog has been vomiting after drinking more than a few sips of water for the last >2 years. Not every time, but every so often she will have bouts of "chugging" water and then vomiting. She will also often vomit if she is fed a snack outside of regular meals. Everything has come back as normal in her regular vet visits but I am wondering- is it possible she has a blockage or something other than behavior is causing this? Thanks!

A blockage would be expected to cause more frequent issues than you describe. I recommend videoing the episodes to show to your vet as there may be clues there, regurgitating water after drinking large amounts of cold water is quite common

    It could be Bailey is drinking water too quickly causing him to vomit. It could also be that he's running around like crazy outside making him sick. But this can also be a sign he isn't well. I'd have him seen by a vet for this.
