My dog is weak, falling, vomiting blood, and can't jump. What's wrong?

Updated On September 23rd, 2025

Pet's info: Dog | Mixed Breed | Male | unneutered

(rambo is not a mixed breed but just a domestic dog which isn't in the categories) he is 3/4years old only. Summer here is very hot, last last month he was vomiting blood. Just lately, he seems weak that when walked, he's not in balance and occasionally falls over. There's one time that he stopped walking and lied down for long and not following the leash. He can't jump or lift his leg up when peeing. What could be wrong? Is he dying?

Hi there! Thanks for letting us take care of you today! When there is evidence of blood in the vomit, that raises concern for things like a gastrointestinal ulcer, gastrointestinal tumor, severe gastroenteritis, foreign body ingestion, among other possibilities. The fact that he has seemed weak afterwards is likely due to being dehydrated and possibly anemic though of course other things are possible.he should be evaluated by a veterinarian as soon as possible for further assessment and treatment as I am afraid he is becoming weaker. Some tests that are usually run include bloodwork (CBC and chemistry panel +/- coagulation profile) and abdominal ultrasound. Thoracic/cervical radiographs may follow. Further diagnostics will be based on the findings up to that point. Treatment will be based on findings. Keeping my fingers crossed that everything will be fine with Rambo!
