My dog drinks water too fast and then vomits. What should I do?

Updated on September 23, 2025

Pet's info: Dog | Golden Retriever | Male | neutered | 3 years and 9 months old | 75 lbs

My dog keeps wanting to drink a whole bowl of water and then pukes it back up. Could this have anything to do with his Lyme disease and the meds that he is on? I just asked this question but feel I should rephrase it a little. If I don’t let him drink the whole 5 cup bowl only like 1 1/2 cups he is fine and keeps the water down with no problems

Thank you for additional information, that really helps! If Moose doesn't puke with only 1.5 cups of water, then it may be he's drinking too much water too fast when you give him 5 cups, leading to the vomiting. I'd give him little bits of water at a time to see if that helps. If it doesn't, then have him seen by a vet.
