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.

Thank you for your question. If your dog is vomiting and having diarrhea and there is blood in either of those things, they need to see a veterinarian. Young dogs are affected by parasites, infectious diseases, and foreign bodies. A veterinarian will be able to examine your dog, see what might be causing this, and get medication so that they can stop having this problem. I hope that all goes well.

Thank you for your question. It sounds, from your description, like your dog should probably see a veterinarian as soon as possible. That sounds like there is starting to be blood in his diarrhea, and if he is vomiting repeatedly, he may need therapy for that. Your veterinarian will be able to examine him, Seymour what might be going on, and get treatment for him so he feels better. I hope that all goes well for him.

Bloody Vomit And Diarrhea

We woke up to bloody vomit and diarrhea everywhere. There’s nothing that we’ve done that’s abnormal. All we can think of is that we take her to the dog park everyday. She hasn’t had any previous illnesses, or any changes to her diet. We’re worried that it’s parvo and we’re hoping someone can confirm or deny.

Thank you for your question. Parvo virus is not as common in one year old dogs as in puppies, but it is possible, especially if she is not vaccinated. Other causes for this may be dietary indiscretion, intestinal infection, or parasites. There is a simple test for Parvo virus, and for parasites, and it would be best to have her seen by a veterinarian, as they can examine her and see what might be going on. Once they know more, they will be able to discuss treatment options. I hope that she is okay.

Thank you for your question. The signs that you are reporting may be related to the food change, or they may be related to something he ate or a parasite. Regardless, with that amount of blood in his stool, and if he is also vomiting, he needs to see a veterinarian as soon as possible. They will be able to examine him, see what might be going on, and get treatment for him. I hope that he is okay.

Thank you for your question. I think if the vomiting and diarrhea has been going on for more than a couple of days, and there is blood in it, I might be concerned. Your little dog may have a stress colitis, and may need help getting over that. It would probably be best to have her seen by a veterinarian as soon as possible, as they can examine her, and see what might be going on, and get treatment for her. To find a veterinarian if you just moved, you can either ask neighbors who have dogs, or look in the general area of your house. I hope that she is okay.

My dog daisy will be 14 next month, doesn’t act like it though. Earlier today she was absolutely fine and then when I got home tonight she had a poop that had jelly-like consistency. She just woke me up in the middle of the night (which she never does) and asked to go out so I took her and her stool has bright red blood. She’s shaking, I think due to a fever. She’s still eating and drinking water. Any thoughts?

Bloody Diarrhea

My dog, Scoot, just recently had a very watery tool with trace amounts of blood. After this, he hasn't been acting like himself. He's also very warm to the touch, warmer than usual for him, but I couldn't check to see if he had a fever. I want to catch the warning flags fast in case of an underlying condition. He also has a very sensitive stomach and has had diarrhea of separate occasions, ones that are soft but not as liquidy as this one. Scoot was left at a family member's house over the weekend and I don't know if he accidentally ate something he shouldn't of(that family member also has 2 smaller dogs who are also much more aggressive, which Scoot could've been stressed out by)

Lethargic
Not Eating

My elderly golden did not eat dinner last night or breakfast this morning. She has been repeatedly vomiting saliva and acts lethargic. I believe the one bout of loose stools was hers but cannot be sure. We have three dogs. The puppy has gotten a lot of attention recently due to being neutered and having diarrhea from a med given. The other two have been left at home as we cart him off to the vet. My husband stated that Honey Bear's last vomit, middle of the night, had some blood in it.
