My dog is vomiting blood and acting lethargic. What should I do?

Updated on September 23rd, 2025

Pet's info: Dog | Lhasa Apso | Male | unneutered | 4 years and 2 months old

Hi! I have a dog who is a Lhasa Apso and he's 4 years old. He's been vomiting the whole day. The vomits are some type of clear liquid and only once did he vomit containing a bit of blood in it. His back is curved and he mostly likes to sit and lay down. I would like to know why is he presenting these symptoms and how can I solve this. Thank you for the attention.

Poor Lupo! I'm sorry to hear that he's sick. Unfortunately, the symptoms you describe are very concerning - repeated episodes of vomiting like this, especially with blood, are often a sign of a serious problem such as pancreatitis, an intestinal obstruction, a systemic illness like liver or kidney disease, or ingestion of something toxic. A curved back and acting very lethargic are signs of abdominal pain. I'm afraid this is not something that can be treated at home - he really needs to see a vet right away, as this may be a life-threatening problem. The vet can do blood work and x-rays to help determine what is causing the vomiting and get him started on appropriate treatment depending on what is found.

It sounds as Nemesis is suffering from a gastrointestinal condition, possibly an infection. it could also be due to ingestion of a foreign body material. i would recommend taking him to the vet the first chance you get, he will need to be checked first, if the vet thinks it's a simple gastrointestinal infection he will need an anti vomiting injection, antibiotics and a special food for a few days in order to get better.

If the vet thinks it is more serious he will need a blood test and possibly an ultrasound in order to find out what is wrong.

Puppy vomiting blood, lethargic, can't stand. What should I do?

I'm so sorry to hear that you and Luffy are going through this. That sounds like a very serious situation. I would recommend putting a bit of sugar in his mouth - perhaps some honey or table sugar which will help raise his blood sugar if that's low. The fresh blood doesn't necessarily mean something is very wrong, because that can occur with any prolonged vomiting due to irritation of the lining of the esophagus and/or stomach. However, all the vomiting along with the lethargy has me very worried. If he's willing to eat at all, mix extra water in with the food to try to keep hydration up. I wish their was more you could do at home, but hope that helps even a little bit.

My dog is lethargic, vomiting blood, and won't eat. What can I do?

Thanks for using Petco Pet Education Center, formerly Petcoach! Loss of appetite and vomiting can be observed with many conditions such as gastroenteritis, dietary indiscretion, kidney disease, pancreatitis, among many other possibilities. I recommend that you have Layka evaluated by your veterinarian for further assessment and treatment. You can offer a bland diet which may help. This diet could be composed of rice, boiled chicken, ham, turkey, lean hamburgers or low fat cottage cheese. They would be able to check for these possibilities and others depending on the findings on exam. Treatment would be based on findings. Good luck and have a great day! Hoping for a speedy recovery!

My puppy is vomiting, lethargic, and pooping blood. What's wrong?

It sounds as Rexi is suffering from a gastrointestinal condition, possibly an infection. it could also be due to ingestion of a foreign body material. i would recommend taking him back to the vet the first chance you get, he will need to have a blood test done and possibly also an xray, if the vet thinks it's a simple gastrointestinal infection he will need an anti vomiting injection, antibiotics and a special food for a few days in order to get better. if it's something more serious, he should stay hospitalized ate the vet's.

My dog is vomiting, pooping blood, and acting strange. Is it serious?

Lacey needs to be seen by veterinarian immediately. This could indicate a severe case of colitis or gastritis, a severe infection, a foreign body, internal bleeding or even something as serious as parvovirus. Dogs can get very dehydrated from this and have secondary issues with her kidneys and liver. Do not give her anything to eat or medication until she is seen by a veterinarian.

Why is my dog drooling blood, not eating, and has stomach pain?

I am sorry to hear about Lola. It sounds like she needs to get to the vet right away. With her symptoms we would worry about things like a bleeding stomach ulcer, trauma due to ingestion of a foreign object, bleeding due to a disease such as Addison's disease, or a blood clotting disorder which can be caused by ingestion of a poison. With all these symptoms you describe I would recommend taking Lola to the vet right away, to an emergency vet if there is one in your area this evening. The vet can examine Lola and will likely recommend bloodwork and x-ray or endoscopy to try to pinpoint the cause of her symptoms and determine the best course of treatment.

My dog is vomiting, lethargic, has diarrhea, and no appetite. Why?

It sounds like your dog is sick. The drooling can be due to nausea, and the lethargy, vomiting, anorexia, and diarrhea could be due to a severe GI illness, eating something rotten, pancreatitis, or a foreign body. I would take your dog into a vet right away for an exam, he sounds quite ill with all these symptoms, and he needs to be medically treated ASAP.

My dog is vomiting and lethargic. What's causing his symptoms?

The cold tongue is not related to any specific disease, whereas the other signs could be compatible with an inflammation infection of the gastrointestinal system and surrounding organs (like pancreas and liver). A clinical examination at your local veterinarian is immediately essential to confirm these clinical suspicions and treat appropriately. Antibiotics and possibly further investigations (like abdominal imaging as ultrasound or radiographs) may be needed.
