Vomiting and bloody stool could be caused by toxin ingestion, parasites, change in diet, toxin ingestion, infectious viral diseases, blockage in the gastrointestinal tract caused by ingestion of a foreign body, or a mass/growth in the gastrointestinal tract. Please have your dogs seen by a veterinarian right away, as bloody diarrhea can be a sign of a more serious issue, can lead to dehydration and anemia, and can be very dangerous if left untreated. I recommend taking in fecal samples from your dogs and explaining the feeding differences to your vet as well, as that may aid them in making a diagnosis. Good luck!

Hi there and thank you for using Petco Pet Education Center, formerly Petcoach to address your concern. I would recommend initiating a bland diet as outlined below. Feed this for at least 3 days beyond the resolution of the bloody stool. If the bloody stool recurs after going back on the regular dog food, I would consider transitioning to a completely different dog food such as Science Diet, Royal Canin or Purina One. I hope this helps guide you in the right direction. Please let me know if you have any other questions or concerns and I would be more than happy to help you further.

My dog has been vomiting yellowish bile in the mornings for a few days now but when he poops there is blood in it and it’s very runny and dark but he doesn’t seem lethargic, he’s running around and eats all his food
Blood in the stool and diarrhea could be caused by parasites, change in diet, toxin ingestion, infectious viral diseases, blockage in the intestines caused by ingestion of a foreign body, or a mass/growth in the gastrointestinal tract. Please make an appointment to have Alfie seen by a veterinarian as soon as possible, as diarrhea and blood in the stool can lead to dehydration and anemia, and can be very dangerous if left untreated. I recommend taking in a fecal sample from Alfie to your vet as well, as that may aid them in making a diagnosis. Good luck, and I hope he feels better soon!

House was broken into last night he was in his room so I didn't think the people messed with him but he has Dirrehea with blood spots and vomited three times in the last 8hrs can't hold down food.
Vomiting with bloody diarrhea is a situation which requires veterinary attention. You don't mention the age of your dog but parvovirus would be a possibility in a younger dog. Other possible causes would include severe GI parasitism, gastroenteritis, hemorrhagic gastroenteritis, ingestion of a foreign object, and inflammatory bowel disease. With a combination of vomiting and blood diarrhea your dog can become dehydrated quickly, so a vet visit is recommended ASAP. They may test your dog's stool sample and take an x-ray to help determine the cause of his symptoms.

Unfortunately, without an exam and thorough workup it would be hard to say why she is vomiting blood or having strange stools as this is a very vague symptom of many different issues. If she's eating leaves of certain plants, they may be toxic or causing ulcers in the GI tract which is leading to issues. Parasites, illnesses, injuries, obstructions, underlying health conditions and more can also cause blood in the vomit or stool, and need to be checked out in person. Complete bloodwork from a local vet, a stool sample test, and X-rays of the abdomen can help narrow down potential causes.

Sammy is about 7 years in human years. Today he vomited a small amount but had a loose bowel movement with blood. Should I try to take him in or should I just monitor him for now. He seems to be taking it easy and told my 4 year grandchild to be c
Diarrhea and throwing up can have many causes. It is basically a problem with the stomach and intestines caused by a food over sensitivity, eating something that does not agree with the dog, intestinal parasites, bacterial infection, viral infection, the weather, food change, stress, etc. I would fast Sammy for 24 hours and then put him on bland food for two days, such as boiled white rice and boiled white boneless chicken meat, fed in small quantities over several feeds and then transition back to his regular food slowly over a few days. If this does not clear up the diarrhea, or there still is blood involved or if the vomiting increases, or if he gets lethargic, he needs to see a veterinarian for an exam as there may be something more serious such as an infection going on.

Dog urine or stool containing blood and mucous..he is active..eating less ...vomited today..what is the cause? Is it life threatening?
Blood in the stool and diarrhea could be caused by parasites, change in diet toxin ingestion, infectious diseases, blockage in the intestines caused by ingestion of a foreign body, or a mass/growth in the gastrointestinal tract. In the case of an unneutered male dog, prostate disease is a possibility as well. Blood in the urine could be due to a urinary tract infection, crystals in the urine, stones in the urinary tract, a mass, toxin ingestion, or trauma to the area. It is important that you have Tom seen by a veterinarian immediately to help determine the cause of the blood and to start treatment. Diarrhea and blood in the stool can lead to dehydration and anemia, and can be very dangerous if left untreated. If you notice him straining to urinate/unable to produce urine, this is a medical emergency and can be life threatening.

What illnesses cause blood in the stool? Why would a dog have a seizure from this?
There are a number of illness that can cause a dog to have blood in the stool, such as parvovirus, hemorrhagic gastroenteritis, GI tumors, trauma or a foreign body in the GI tract, GI ulcers, or ingesting something toxic. If your dog ate something toxic or has GI tumors that have spread, those could certainly lead to seizures. The only way to know for sure what is causing blood in the stool and seizures is to have your dog seen by a vet, and I recommend having it seen asap. Best of lucK!

Hi! I think I changed my puppies food too fast and now he has diarrhea and has thrown up a couple of times. Now today he has a bloody stool but he’s acting playful still. What should I do please?!
Oh no poor puppy! You are right that changing food too quickly can cause these issues, and the problem here is that he is vomiting, has diarrhea, and now has bloody stool. Even though he's acting normally, his symptoms need to be checked out by a vet immediately. Please take him into one now to get these treated. Best of luck.

Thanks for using Boop by Petco! Vomiting and bloody stools can occur from many conditions such as foreign body ingestion and obstruction, pancreatitis, gastroenteritis, dietary indiscretion, among other possibilities. If he is having seizures that make this very serious as this is possibly unrelated and could be seen with conditions such as low blood sugar from vomiting, brain inflammation, epilepsy, among other possibilities. I recommend that you have Bruno evaluated by your veterinarian for further assessment and treatment. This will likely require bloodwork and abdominal imaging in terms of diagnostics and possibly an MRI. Treatment would be based on findings. At the very least your veterinarian could start him on medications to make him feel better. In the meantime, keep water available at all times to try to prevent dehydration. Good luck and have a good day!

If Auggie hasn't had a stool sample checked it would probably be helpful to rule out intestinal parasites. His symptoms could also be caused by inflammatory bowel disease or a food sensitivity. If you've seen three different vets and feel that you're not making progress with Auggie you could have your vet refer you to an internal medicine specialist.

It sounds as your pet is suffering from a gastrointestinal condition, possibly an infection. i would recommend taking Them to the vet the first chance you get, they will need to be checked first, if the vet thinks it's a simple gastrointestinal infection they will need an anti vomiting injection, antibiotics and a special food for a few days in order to get better.
