Why did my dog throw up after drinking water but seems fine?

My dog was drinking water and afterwards he threw up a small amount of what looked like saliva. He ate before and was playing like normal. I actually asked this question but just wanted to add info: his bowl of water was full, maybe some water went up his nose? We went to the park this afternoon and he licked grass and dig a hole on the dirt, could that have caused it? We just came back from our walk, he didn’t poop but otherwise seems normal, even played with other dogs and made a new friend.

It could be some water went up Charlie's nose if he had a full bowl, or drinking too quickly after playing could have lead to nausea and a bit of vomiting. If he's otherwise acting normally, I'd keep an eye on him for now. Best of luck.

Poor Charlie! It could be he was drinking too fast, and that caused him to vomit a bit. I'd keep an eye on him for now since he's acting normally, and offer him smaller amounts of water at a time to see if that helps. If he vomits water again or develops other signs such as lethargy and anorexia, then I would have him seen by a vet. Best of luck.

This seems more likely to be due to regurgitation rather than vomiting. Commonly, megaesophagus (pathological enlargement of the esophagus) is suspected in these cases and possible differentials have to be ruled out to establish a diagnosis. Neuromuscular disease (e.g., myasthenia gravis, distemper, myositis), esophageal masses, Toxicity (e.g., lead, thallium), idiopathic inflammation of esophagus are all possible. A clinical examination at your local veterinarian is immediately essential to confirm these clinical suspicions and treat appropriately. Antibiotics and possibly further investigations (like abdominal imaging as ultrasound or radiographs) may be needed.

Vomiting directly after eating is possibly regurgitation rather than vomiting. If he eats very quickly, he could be taking in so so much so quickly that his stomach can't handle it, his esophagus fills and activate the gag reflex. Vomiting hours later could be a sign of a problem. Since this has been going on for a few days, I think it's time to get Lucky seen by your vet, especially since he didn't keep water down today. It could be as simple as a hairball, or he could have something more serious going on, but continued vomiting is concerning.

Hello. Regurgitation of food can occasionally happen, especially if a puppy drinks too much water too fast. The food looks intact because many dogs never totally chew their food. This is very normal for many pets. If the vomiting continues, or Jace becomes lethargic, anorexic, shows any signs or pain or fever, please call your veterinarian.
