Why is my dog throwing up, eating grass, and drinking lots of water?

Updated On September 23rd, 2025

Pet's info: Dog | Labrador Retriever | Male | neutered | 11 years and 1 month old

My dog Brady, he is an 11 year old black lab mix, has been having a lot of trouble today. At about 10: AM, he threw up. It is now 1:25, and his stomach has been making squeaking noises. I took him out about 30 minutes ago, and he just ate grass. When we came back inside, he started coughing and gagging, so we went back outside and he threw up twice, on my neighbor's lawn of all places. Now, he's been wandering around and drinking a lot of water.

That could be simply dietary related or related to a gastrointestinal inflammation,infection. I would suggest to withhold food for the next 8-12 hours and then start feeding with a bland diet based on boiled chicken and rice in small portion every 6 hours for the following 48hours. Then gradually reintroduce the normal diet over 5 days. I would definitively recommend a veterinary check up if the signs persist or you notice diarrhoea, more vomiting, lethargy or inappetence.

    It sounds like poor Eris is sick! She could be suffering from a GI illness, may have eaten something rotten, could have a foreign body, or could have pancreatitis. I can give you a home remedy to try to see if that helps before having to take her into the vet. Withhold food for 12-24 hours, then feed a bland diet of boiled white meat chicken (no bones) and white rice in small amounts several times a day for a couple of days. Then slowly add back in her normal diet. If the vomiting continues in the absence of food, she vomits the bland diet, develops diarrhea, stops drinking water, starts vomiting water, or becomes very lethargic, she will need to see a vet right away. I hope this helps!
