Blood in faeces can be due to many disorders. It can be due to inflammation due to eating something off, ranging all the way to more serious issues such as tumours of the gut. Due to the many possibilities it is imperative to have the dog examined by a vet. This is the quickest and most reliable way to get to the bottom of what is going on. Hopefully it will be something fairly straightforward.

    Hi there and thank you for using Petco Pet Education Center, formerly Petcoach to address your concern. If Daddy is doing fine otherwise and is not having any other symptoms such as vomiting, lethargy, inappetance, etc. I would monitor for now. I would recommend initiating a bland diet as outlined below and feed this for at least 3 days beyond the resolution of the blood in the stool. If the blood does not resolve or becomes more persistent, I would recommend having a veterinarian examine Daddy so that the most appropriate diagnostic and treatment recommendations can be made. I hope this helps! Please let me know if you have any other questions or concerns and I would be more than happy to help you further. 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.

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.

I'm sorry to hear that Bruce has been so sick. Decreased appetite, vomiting and bloody stools going on for 2 weeks is quite concerning. If blood work did not give a definitive answer, it may be time to consider imaging such as x-rays or an ultrasound. Potential causes for these symptoms include infections, dietary intolerances or even some types of cancer. An ultrasound may be beneficial in evaluating the abdominal organs to give us a better idea of what's going on.

11 yo, mixed breed, medium sized, neutered male dog has chronic bloody stool (red/pink, not runny), stomach noises, and very foul gas. This has happened on and off for 6 months, from 1 to 4 times per month. Otherwise, he seems fine. He is on a stric
I would recommend that you talk to your vet about an abdominal ultrasound. Also, if your vet has not performed a rectal exam, that would also be a good thing to ask about. Since he is 11, my biggest concern would be a potential tumor. It could also be that he has inflammatory bowel disease. You could also use a probiotic for him which may be beneficial. Talk to your vet about a fiber supplement such as Metamucil as well, which could also be helpful. Thanks for asking Boop by Petco!

Blood in stool what should I do. I have a one year gsd
It sounds like your dog has a case of colitis, or an inflammation of the colon, resulting in an increase in the volume and frequency of stools. Colitis can be caused by many different things. Some of the more common causes include intestinal parasites, dietary indiscretion, food intolerance, irritable bowel disease, pancreatitis, a foreign body/blockage and viruses. Since there is blood in the stool I would recommend taking your dog in to your vet to be examined. They will likely want to check a stool sample and may recommend some lab work, a dietary change, and/or antibiotics. I hope this helps. Thanks for using Boop by Petco. Best of luck.

9 yr old dog, vomit x 2 last night and this am, ate afterward no vomit after that but had blood (bright red) in stool a couple hours ago. Emergency or appointment on Monday?
Bright red blood in the feces is not normal, and could be caused by hemorrhagic gastroenteritis, a foreign body, eating something rotten, or cancer. Given Cody's age and the fact that he was vomiting previously, it would be best for him to see an emergency vet in my opinion.

My dog honey who is 15years old she's a jack Russell and she is pooping blood I'm very worried about her
Hello, and thanks for using Boop by Petco. Poor Honey! I'm concerned about the amount of blood in that stool. It is very common to see small specks or streaks of blood in diarrhea - but it is more concerning in cases like this where the dog appears to be passing more blood than stool. This can be a sign of HGE or Hemorrhagic Gastroenteritis, which can be a dangerous condition and warrants an immediate trip to the vet. Your vet will probably want to look at a fecal sample to check for intestinal parasites, and will likely recommend bloodwork (particularly a CBC) to look for evidence of anemia or the changes characteristic of HGE. Depending on Honey's overall attitude, exam findings, and labwork findings, they may be able to manage her as an outpatient with medication to control the diarrhea (and likely fluids to help with dehydration), or they may recommend she be hospitalized for IV fluids and injectable medications. Regardless, I definitely recommend having her seen sooner than

It's worth getting it checked out with your vet, in case he has picked up an intestinal parasite or has some irritation in his lower GI tract. That the blood is red means it's fresh, therefore being shed very low in the GI tract or his rectum or anus. It may be anal glands that are inflamed, there are a few possibilities. Your vet will do an exam, some labwork, and based on these results will be better able tot ell you what is going on and the best treatment options for your dog.

My dog is 13. He has been on a round of amoxicillin, sucralfate and metronidazole for an infection. He has been off the meds for 4 days and he now again has blood in his poop.
Hi, thanks for using Boop by Petco! Poor Sebby! If the bloody stool is reoccurring and due to his age I would do blood work, be sure a rectal exam was done, fecal testing, and his anal glands were checked. I would consider a prescription GI diet for several weeks and a probiotic. He may have underlying intestinal disease like inflammatory bowel disease, low B12, pancreatic disease or simple isn't digesting his food the same way. I wish you the best!

The past 2 days my dog has been completely acting fine all day and night, but the past 2 mornings he has been popping blood. He will poop through out the day and not have any blood but does in the morning.
Fresh blood in loose stool can be caused by a food indiscretion, intestinal parasites, inflammation of the large bowel and or rectum, an intestinal injury, stress, and a few other causes. Since bleeding into the bowel means that there is an open blood vessel through which intestinal bacteria have access to areas of the body where they should not be and cause more disease. So it is important that your dog needs to be seen by a veterinarian for an exam and needs to have a fecal exam as well, medications according to the exam findings and diagnosis, and prescription antibiotics. Please schedule an appointment with your vet. In the meantime you can start feeding your dog some bland food such as boiled white rice and boiled white boneless chicken meat, fed in small quantities over several feeds and then transition back to regular food slowly over a few days.

my 10 yr old female shih tzu is pooping blood but eating and acting normal.
Hi. Blood in the stool, if bright red, can be caused by anything that irritates the GI tract. These would include dietary indiscretion, stress, parasites, infection, all the way up to cancer/mass ( has to be on the list with older pets). It's great news she is eating and acting normal. Obviously though, the blood is abnormal. I would get her in for an exam, a fecal test, and a rectal exam by your veterinarian.
