Why is my dog throwing up blood and pooping blood? Is it serious?
Vomiting blood is serious. The GI upset could be due to many conditions including eating something she shouldn't have, bacterial over growth, parasites (worms and giardia), poison, a bleeding disorder, pancreatitis, cancer or intestinal blockage. I recommend to have your pup examined by the veterinarian today. Try to remember to take in a stool sample. The doctor will check her for parasites and bacterial over growth and other diagnostics may be recommended as well. She needs the correct diagnosis in order to receive appropriate care. She also needs medications and possible fluids. I hope Coco starts feeling better quickly! Please feel free to post any additional questions!
