How to Manage Vomiting Blood at Home

If your dog has vomited blood, you may be panicking and unsure of what to do next. It is essential to remain calm, as your dog may feel more stressed if they sense your anxiety. Here are some immediate steps to take:

  1. Remove any potential hazards from your dog’s environment, such as toxic substances, small objects, or sharp items.
  2. Do not feed your dog for 12-24 hours to give their stomach time to rest and recover.
  3. Provide small amounts of water frequently, to keep your dog hydrated.
  4. Observe your dog closely for any changes in their behavior or other symptoms, such as lethargy, diarrhea, or abdominal pain.

It is important to note that if your dog shows any signs of distress or their condition worsens, you should seek veterinary help immediately. Additionally, if you suspect your dog has ingested a toxic substance or a foreign object, do not wait to consult a veterinarian. Read our article on My dog ate something it shouldn’t have!

When to Seek Veterinary Help for a Dog Vomiting Blood

As previously mentioned, it is crucial to consult a veterinarian when your dog is vomiting blood, especially if the vomiting is accompanied by other symptoms like diarrhea, lethargy, or abdominal pain. In some cases, untreated vomiting may lead to severe dehydration and other complications.

Your veterinarian will be able to provide a thorough examination, run diagnostic tests, and recommend the most appropriate treatment options for your dog. The sooner you seek help, the better the chances of a successful recovery for your beloved pet.


Seeing your dog vomit blood can be a frightening experience, but it is essential to remain calm and act quickly. Evaluate your dog’s situation, remove any hazards from their environment, and seek veterinary help as soon as possible. Remember that your dog’s well-being depends on your ability to respond appropriately to their needs, so educate yourself, consult with professionals, and provide the best possible care for your beloved pet.
