My dog threw up blood and isn't eating. When should I see a vet?

Pet's info: Dog | Australian Shepherd | Male | neutered | 4 years old | 60 lbs
My dog vomited blood diluted bile and hasn't eaten yet today but was acting fine yesterday. He had eaten meat a couple days ago but I can't think of what else he may have gotten into as he is around us constantly. We are on a steep icy back road in the mountains that we shouldn't be driving on. Is it okay if I just keep an eye on him for now instead of rushing to the vet? He is has G.I. problems as a rule so he eats Hills Digestive Support. His stools have been okay and he is resting.

If it was a one time instance, then yes, it should be OK to just watch him right now. I do think he should see a vet for sure if it happens again - bloody vomit is not a good sign. If you have some on hand, you can give him oral Omeprazole 10mg once per day. It would be a good idea. Hope this helps. Best wishes.

If the vomiting continues or he seems lethargic than he should be seen by a vet. He could have a parasite or infection and your vet can run some diagnostic tests, if needed, to help diagnose. He may need a dewormer, antibiotics, antacid, gastrointestinal protectant, or other medications depending on the cause.

Poor Spock! There are a number of things that could cause vomiting blood that would not show up on x-rays. Some possibilities would include a bleeding stomach ulcer, HGE (hemorrhagic gastroenteritis), a systemic bleeding disorder of some kind, ingestion of something toxic, or irritation to the stomach and esophagus from repeated episodes of vomiting. It's good that his bloodwork was normal also, as this makes it less likely that the problem is something serious :) He should be feeling better with medication from your vet within the next 24 hours. If not, I would recommend calling your vet or taking Spock back for a recheck to make sure that everything is okay.

I'm sorry Spock isn't doing well at the moment! If he had a foreign body causing a a complete or partial obstruction, I would expect to see diarrhea or a complete cessation of pooping. I agree that if the vet suspected a foreign body, she would have have done more testing such as an exploratory surgery. I would keep giving Spock his medications as prescribed and the diet. I hope this gives you peace of mind and he keeps getting better!
