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.

Bloody Vomit And Bloody Diahrrhea

Two weeks ago our 8 year old wheaten terrier started vomited, which progressed over a few hours to bloody diahrrea. We tok her to the emergency vet who gave her fluids and and an antibiotic. She rapidly improved and was fine the next day. Five days later our other dog developed the same symptoms. Our regular vet gave him the same antibiotic our other dog received and he also improved in 24 hours. Now, a week, later our wheaten (the one who had it first) is experiencing the same symptoms again. I'm at my wits end here.

Has Symptoms

Diarrhea, Vomiting

My mother has 2 dogs at home one is Affenpinscher and the other is a Golden Retriever. They are both mutts small dogs and they always played together, the Golden Retriever always liked to look out the window and stays to look at the view to see how high we are. Usually he likes to wait for other dogs and he gets excited to bark at them but my mom calms him down. When visitors come over he likes to play rough with other people, when he sees people that he does not know he tries to growl at them the very first time. One last thought before I post the bad news, he likes to go for walks when we say that we want to go for a walk. Later that then we found him that he got sick, my mom figures that he got into something poison or ate something bad, he has been sick for 4 days an we tried to give him tylonal and gravel but nothing worked, he kept throwing up and pooping diarrehea for 4 days we tried giving him water or feeding him especially the good healthy food but he refused to eat or drink for 4 days and he was slow, didn't want to play or anything. On the last day he went to my mom an my dad an left out of the room. The last day he had diarrehea and pooped out blood twice. We tried to call the vet but we had no money to afford one so we didn't know what to do, the next day my mom woke me up with bad news saying that Jack is dead so she started crying an I gave her a hugs, he was lying stiff on the floor but he was still warm, if anything happens to this black dog what do we do if we can't afford a vet? One last thing is we tried to call a funeral for him but that cost money as well so we had no choice to burry him in the yard.

It is distressing to lose a loved one, especially when you had few options and couldn’t visit a Veterinarian; without performing a necropsy on Jack I cannot say what the cause of death was and there are hundreds of possible causes if poisoning is suspected. Vomiting and diarrhoea are vague symptoms and may be attributable to many different conditions including poisoning, infections, parasites, internal disease (liver, kidney) among other causes. I wish I could give some closure to you on giving you a cause but I cannot, you should try to search for a charity clinic or other organisation near you to look at the other dog to be on the safe side.

Has Symptoms

Vomitting & Diarrhea

She has been having loose, bloody stools the past 2 days. Vomitted x1 yellow mucous during those 2 days. Although she is eating & drinking, she seems to be losing weight. Just changed food about a week ago due to her not being able to chew her food well any longer as she doesn't have many teeth left. Our vet is closed for the day & I don't know that I can get her in until Tuesday. What should I do?

If Savannah seems to be generally feeling okay other than the stools, she may be fine to be seen on Tuesday, but Monday would be better. In the meantime, you can try feeding her a mixture of boiled chicken and rice and see if that helps with the stools. If she continues to vomit, becomes lethargic or isn't wanting to eat, she should be seen by your nearest emergency veterinarian.

This is the second time this has happened... My dog is a 3yr old Golden Retriever and out of the blue he suddenly just has no appetite for food, and then ends up pooping blood with his stool. We changed his food the first time this happened along with medicine food and powder, but 9 months later he's back to this again. He's been trying to poop and has been vomiting around the clock. He does drink water though, but he just doesn't want to eat much if anything. He got tested the first time this happened and the vet didn't find anything serious, and just said it could just be his food, which is why we changed it. But it's happening again, why?

Since it has been 9 months since this has happened, I'm not sure that I would say the two incidents are related. If Enzo is vomiting, not eating, and having bloody diarrhea, he needs to be seen by a veterinarian today to see if he needs any supportive care, and to figure out what is wrong and get treatment.

Pooping And Pukeing A Lot
Red Seeds In Puke
Not Eating Very Much

We recently when into the vet because we same this tumor thing on his leg. The vet doesn’t know what’s wrong and we are going to have to go back in 2 weeks. And just sense yesterday we had pooped and puked a lot but just the recent time he puked and pooped it looked like there was blood in it.. it was pink with red looking seeds inside. I don’t know what the poop looked like because I wasn’t the one cleaning it up (it was in the house) he was eating grass outside. Also he seems very active when he is outside but inside he looks like scared or sad. We have a raspberry bush that he could have eaten off of but we do not know. What would you suggest doing and what could it be? Also he hasn’t been scarfing down his food like he normally does.. he waits for about 3 hours before he ends up eating it.

Since you're not sure if Sparky is vomiting blood or if there are seeds that are coloring the vomit, it would be a good idea to get a sample of his stool and have him seen for this problem by your veterinarian, as it seems unrelated to the growth that you noticed on his leg. They'll be able to see what might be going on with him and give him any treatment that he may need.

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)

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.
