Seeing your dog throw up blood — also known as hematemesis — is alarming, and it’s a symptom that needs immediate attention. It’s a sign that something isn’t right, even if your dog seems to be acting normally otherwise.

We’ll walk you through some of the potential reasons why your dog is throwing up blood, when to seek emergency care, how your vet will diagnose the problem, possible treatments, and what you can do to prevent it from happening again.
