What is Pooping Blood and Vomiting?

As a pet parent, you are certain to be alarmed if you observe your dog vomiting and pooping blood. Some dogs will vomit and have bloody diarrhea, but continue to eat or drink. If you observe that your dog is pooping blood and vomiting, but refuses to eat or drink, get him to the vet immediately. While some causes of your dog pooping blood and vomiting are not serious, others are life-threatening. It is always best to err on the side of caution. Several conditions can cause your dog to have a bloody stool and vomit:

  • Hemorrhagic gastroenteritis
  • Intestinal obstruction
  • Parvovirus
  • Parasites
  • Changes in your dog’s diet

Why Pooping Blood and Vomiting Occurs in Dogs

Hemorrhagic Gastroenteritis

Hemorrhagic gastroenteritis is characterized by sudden onset of bloody diarrhea in a dog with no previous issues. Vomiting may or may not accompany the bloody diarrhea. The refusal to eat (anorexia) and listlessness have also been observed. Dehydration can soon take place as the body empties of liquid and it is not replaced. This is a situation in which you need to get your pup to the vet as soon as possible. Shock can occur without treatment. Stress is thought to be a factor in this condition. Toy breeds are thought to have a higher instance of hemorrhagic gastroenteritis, especially between the ages of two and four. While these dogs have a higher occurrence of the disease, any breed of dog can acquire it. Gender is nonspecific as well. 

Intestinal Obstruction

Because dogs eat most anything, intestinal obstructions can be fairly common occurrences. An intestinal obstruction can be a partial blocking of the small intestines. Blood supply to the GI tract can be cut off or compromised during a blockage, and, without treatment, sections of the intestine may die. Perforations may occur as a result. Bacteria can seep into the gut, causing septic peritonitis. Unfortunately, emergency surgery is often required to eliminate an obstruction. 

Parvovirus

Parvovirus is a highly contagious viral infection that normally affects young dogs (ages six weeks to six months) that have not completed all their immunizations. Transmission occurs when a dog comes in contact with contaminated objects – and these objects can be food bowls, shoes, clothing, even the ground. The virus can live for up to a year, and it is not easily eradicated. Parvovirus is resistant to most household cleaners; bleach is basically the only cleaner strong enough to kill parvovirus. Parvo can be transmitted when a dog licks any material that has come in contact with the virus – including feces – and then licks himself. Initial symptoms include fever and lethargy. Dogs may refuse food and water. Within 48 hours, profuse vomiting and diarrhea will begin. Parvo has a higher occurrence in Rottweilers, German Shepherds, and Dobermans.

Parasites

One of the most common causes of bloody stool in dogs is parasites. Hookworms, roundworms, and whipworms are known to cause blood in the stool. Coccidia is another parasite that has been associated with bloody stools. No breed is any more susceptible to parasites than others.

Changes in Your Dog’s Diet

Overeating, indiscriminate eating, or changing your dog’s diet may cause stress on the gastrointestinal tract, leading to bloody stools. Food allergies can also cause bloody diarrhea, and unintentionally eating spoiled food can cause your dog to have bloody diarrhea and vomiting as well.

What to do if your Dog is Pooping Blood and Vomiting

If you suspect your dog has parvovirus, get him to the vet immediately. Puppies can dehydrate quickly and sepsis can set in. Once your dog is vomiting and experiencing diarrhea, the virus has already progressed greatly.

If your dog has hemorrhagic gastroenteritis, your vet will have to do many tests to eliminate other possible causes. There is no known exact cause of the condition. However, a dog that has had one incidence of hemorrhagic gastroenteritis is likely to have more episodes. You may actually see evidence of parasites in your dog’s bloody diarrhea. Your vet will take a stool sample and examine it for parasites. If they are present, he will prescribe dewormer. If your dog has an intestinal obstruction, he will be in a good deal of pain in addition to the bloody stool. Your vet may have to do x-rays in order to confirm the diagnosis. Experts recommend gradually changing your dog’s diet in order to avoid gastrointestinal stress.

Prevention of Pooping Blood and Vomiting

Always take caution when taking your unvaccinated dog into high-traffic areas such as the vet or groomer. Also, be aware that parvo can live on the ground for up to a year. Your dog will receive the last vaccination against parvo at around sixteen weeks. Until then, take extra caution around strange dogs. Stress is a known factor in dogs with hemorrhagic gastroenteritis, so try to minimize stress in toy breeds. Keeping your dog regularly wormed will help prevent intestinal parasites. 

Cost of Pooping Blood and Vomiting

Treating parvovirus in dogs can be an expensive treatment ranging from $500 to $12,000. This cost will be dependent upon the stage of the virus when you get to the vet. The exam, initial tests and possible IV fluids can start at $50 and total up to $500. Medications to treat parvo can range from $60 to $114, and 24 hour care can cost up to $175. Multiple days in vet care can multiply this cost. The average cost to treat hemorrhagic gastroenteritis is $1100.

Blood In Stool

Hello, my name is Iris I have a 16yr old chihuahua named Buttercup. About 6 months ago she was diagnosed with mamarary cancer she has recently developed another one which equals two fairly large balls on her breasts. Estimating the size of half an egg. She’s been doing fine eating and drinking until early this morning she vomited and had blood in her stool. She did not make it outside so I know she is not feeling okay. She is currently just laying in her bed she isn’t her self. My biggest concern is if she is hurting. I know her time is coming and I want to do the best thing for her,
Thank you.

Thank you for your email. I'm sorry that Buttercup is having these problems. It would be best to have her seen by your veterinarina to treat this episode of vomiting and bloody diarrhea - it may be related to the mammary tumors, but may be unrelated, and your veterinarian will be able to examine her, recommend any tests that might be necessary, and get her treatment so that she feels better. Older animals can become dehydrated quickly, so it would be best to have her seen as soon as possible. I hope that she is okay.

Last night my Chi-winnie dog Chip had a extremely full stomach. This morning he used the bathroom and his stool was normal but really really hard. I proceeded to put him in his cage and i went to work. At 12 I went to let him out and he ran straight to the grass and used the Restroom but with blood in his water like stool. He was also very constipated. After he used the bathroom he vomited twice. He acted no different, playful as ever just that accident. He still wanted to eat my burger and still acted himself. I dont know what to do. Im scared! He is 1.5 years old and has had 1 or 2 parvo shots and has not be wormed before. Please help!

Thank you for your email. I'm confused by your question, whether he is having watery stool or hard stool, or both? Without examining him, I can't determine what might be wrong, but common causes for intestinal upset include parasites, dietary indiscretion, and intestinal infections. It would be best to have him examined by your veterinarian as soon as possible to see if he has diarrhea, or is constipated, and get him on treatment, especially since you saw blood in his stool. I hope that everything goes well for him!

Thank you for your email. I'm sorry that Moon Moon has Parvo virus - that can be a very serious disease. Without examining him, I can't comment on whether he is improving, but sometimes puppies that have Parvo virus need to be hospitalized and on IV fluids to keep them hydrated while they recover. It would be best to talk to your veterinarian about whether he would benefit from that therapy, or if he seems to be improving slowly. I hope that he is okay.

Vomiting
Blood In Stool

I have a 2 y.o. shih-tzu-lhasa apso. A friend who was unable to care for him gave him to us. He is not up-to-date with his vaccines, and the vet wants us to discover what has already been given, or not given, to the dog as vaccine. Luffy is always energetic, but he seems to be having stomach problems. He eats too fast (even beating our pitbull to finish the meal first) and drinks too much water. He'll poop runny, bloody stool later on. Sometimes, he throws up the food he ate (they're all intact, like he did not chew the food at all). He has better stool (less or with no blood) if we feed him less, and only with hard food that he'll be forced to chew. We do not leave water around because he'll drink it all. Can you advice us what's going on with Luffy? This is not an everyday situation for him.

Thank you for your email. Without examining Luffy, I can't coment on what might be causing that behavior, but it would be a good idea to have him examined by your veteirnarian, and checked for parasites, as well as some routine bloodwork. Your veterinarian will be able to find some answers for you and make him more comfortable. I hope that everything goes well for him!

Bloody runny stool

Hi. My fiancee aunt and uncle gave us a puppy that they had gotten as a Christmas present because they are in and out of the hospital so much they couldn't take care of her. We took her in and we noticed she had bloody and runny stools. His uncle had told me she had recently gotten her 10 week shots and a dewormer. But it has been a week and a half later that she's still pooping blood and now she is throwing up. Shes still very energetic and plays with my year and a half pitbull and runs around with him outside. I don't know what to do. Ive tried everything, switching her food, making sure she doesn't eat anything outside, making sure she's getting enough to eat and she eats slow. I don't know what to do.

Thank you for your email. Snoopy should have an examination with your veterinarian and make sure that she is up to date on vaccines, check a fecal sample for parasites, and be checked out for the cause of the vomiting and diarrhea. If she had a vaccine at 10 weeks, she should have had a booster at 13 and 16 weeks, so she is not up to date on vaccines, and is in danger of contagious diseases like Parvo virus. If she has not had a deworming treatment, she may have intestinal parasites causing her GI signs. I hope that she does well.

My fiancees uncle had also told him yesterday when he talked to him that she had eaten a rawhide bone and that could possibly be blocking something. But I figure it would have passed by now.

I have a 7month old female Alaskan Malamute who started having diarrhea a few hours ago. That has now turned into vomiting and diarrhea with both have some small amounts of blood in it. We made a small change to her diet with a new type of treat, it was also a very stressful day for her, we brought a new puppy into the house. Could the stress of the new puppy mixed with the new treat be the causes of the problem? She has had problems with new foods before, but we have never seen any blood, she has a sensitive tummy. She is up to date on all her shots so I don't think it is parvo, she hasn't eaten anything that would be causing trauma/blockage that I know of. Thank you!

Michele King
Dr. Michele King, DVM

Thank you for contacting us about Kiara. Her problems may be cause by food intolerance, dietary indiscretion, parasites, or stress. Parvovirus is still a concern, since you have two puppies in the house now, even though she is vaccinated. She needs to be seen by your veterinarian this morning, as she seems to be deteriorating and developing more severe signs, with the blood in her diarrhea and vomit. They will likely test for Parvovirus, just to be sure, and check her fecal for parasites.

It may take some time for Sophie to start feeling better, but it depends on what has occurred since Sophie may have ate something poisonous, have an obstruction or ate something rotten (or a mix of all three); so it will take some time to see any improvement. If you don’t see any improvement, an x-ray to look for foreign objects may be useful as well as continuing the antibiotic therapy. Regards Dr Callum Turner DVM

Just yesterday, Rosie stopped eating and drinking her food and water and today, she was restless all day and had been pooping out blood that smells like blood and had also been vomiting out gluey white stuffs.I have another dog too, her brother, Brownie and he is also showing signs of lethargy and he also hadn't been eating much. He just lies down there, restless. Is it worms or parvo or does is have anything to do together with the chicken brest that I had given them? The chicken has this smell like they had poured chemical onto it to keep it fresh(my other dogs who had eaten the same chicken has been pooping out blood too but then they aren't showing any signs) but then can it be rats too? Because the place that I'm living at has a lot of rats.

Callum Turner
Dr. Callum Turner, DVM
1828 Recommendations
There are many different possible causes for the symptoms you are describing, but if you haven’t had any of your dogs vaccinated then parvo is a strong possibility; you should take one of your dogs with the most severe symptoms to your Veterinarian for an examination to determine whether it is parvo or something else. If it is parvo, you will need to give a lot of supportive care preferably intravenous fluids along with antibiotics. Regards Dr Callum Turner DVM

If Drax is not wanting to eat or drink, try to at least get him to drink by syringing water into his mouth as this may help him keep somewhat hydrated; you should continue with the metronidazole but if he is vomiting up blood or defecating blood you should visit your Veterinarian or an Emergency Veterinarian for a check and some intravenous fluids if required.

What is wrong with my dog? He has had diarrhea for a week and a half now. I've been to the vet 3 times and they don't fix the problem. I he got a blood test and everything was normal besides his pancreas levels are higher than normal. The vet prescribed probiotics and pepcid ac. After giving him the pepcid ac he was back to normal for about a day but now he seems worse than before and now his diarrhea is really bloody and it looks really bad. He seems to strain when he poops. when he urinates it don't seem like a solid stream. His diarrhea is in more then one place so he goes then stops and then moves and goes again. He still eats but I have to hand feed it to him, I made him rice and boiled chicken for dinner. I just want someone to help him, ive got another appointment for him in the morning, I've been to the vet 3 times since this started about 2 weeks ago and I've been to 2 different vets for answers and nobody can seem to help me or my dog and his conditions are getting worse with each day that passes, What do I do?

In this cases there are various causes for the symptoms which you are describing which may include infections, poisoning, dietary issues, pancreatitis, parasites, foreign objects, colitis among other causes. I would recommend withholding food for 24 hours and then starting him on the boiled chicken and rice again; this may help to ‘reset’ his system. Other than that, supportive care and ensuring that Zippo stays hydrated is important. Regards Dr Callum Turner DVM

Sometimes fasting a dog for 24 or 48 hours can help with bouts of vomiting and diarrhoea especially when the pancreas is involved, it sort of resets the system.
