My 9-week puppy has blood and mucus in stool, acting normal. What now?

Updated on September 23rd, 2025

Pet's info: Dog | Mixed Breed Small (up to 22lb) | Male | unneutered | 2 months and 1 day old | 3 lbs

Hello, my new 9 week old cavapoo puppy has mucous and blood in his stool. Other than that he’s acting totally normal. I’m not sure what to do as we don’t have a vet yet (will be making an appointment for next week). Any suggestions??

Fresh-appearing blood in the stool often indicates an infection or irritation of the colon. Sometimes, in the case of an irritated colon, this can be remedied by feeding a bland diet (i.e. cooked chicken and rice) for a few days. It's also good to ensure plenty of fresh water is always available. You can give that a try as you wait for the vet appointment.

It's good that he's otherwise acting normal. This lowers any suspicion of a more severe disease affecting the colon.

I hope that helps and Bowie gets better soon.

Thank you for submitting your question Dash. Blood in the stool can be a serious sign. What fecal tests did he have with his veterinarian? I typically test puppies for parvovirus, giardia, intestinal parasites such as worms and other protozoa as well as assessing the bacterial populations. This takes about 4 different tests to complete. If all of these tests come back negative or normal, I will typically still deworm the puppy and start an antibiotic. Diet should also be discussed. If he had a normal fecal test on his first puppy visit and has since developed this sign, he needs to see his veterinarian again today. The tests I described above will likely be warranted. Mucus and blood typically indicate inflammation in the colon. This is most commonly due to an infection, but can be diet related. Regardless,he will need treatment. I hope this information helps!

Thank you for submitting your question regarding Nashville. I recommend that he sees a veterinarian. Blood and mucus in the diarrhea can be a serious sign in such a young puppy. He will likely need fecal testing to look for infectious causes of the diarrhea. I also worry that he will be dehydrated from losing excessive fluid in the stool. Based on his exam findings, medication and other necessary treatment can be prescribed. I hope this information helps!

It's probably not IBD, but it could be food intolerance or allergies, intestinal parasites, dietary indiscretion, bacterial or viral infection, stress colitis, a mass in the colon, etc. If there are no other symptoms, I think it is fine to monitor at home.

What should I do if my 11-week-old puppy has blood in her stool?

This is usually dietary related and if no other signs are present at this stage, the problem could be managed by start feeding with a bland diet based on boiled chicken and rice in small portion every 6 hours for the following 48hours. Then gradually reintroduce the normal diet over 5 days. I would definitively recommend a veterinary check up if the signs persist or you notice diarrhoea, vomiting, lethargy or inappetence. If that is the case antibiotics may be needed.

Why is my puppy's poop bloody but he's acting totally normal?

I'm sorry to hear Frank is having an issue! If he is otherwise acting normally you can try to offer him a bland diet of boiled chicken and sweet potato or rice to see if this helps. If the diarrhea persists, he starts vomiting , stops eating or becomes lethargic he will need to be examined by a veterinarian right away. Puppies can easily get intestinal parasites so it would be a good idea to have your veterinarian check a stool sample on Frank. Thanks for using Petco Pet Education Center, formerly Petcoach and I hope Frank is on the mend soon!

My dog's poop has mucus and is dark. Should I take him to the vet?

Thank you for submitting your question regarding Kai. Mucus covering the stool typically indicates inflammation in the colon. This is not normal. If she is eating, drinking and acting normal, then it is not likely necessary to seek emergency veterinary care. If she starts acting ill or you see obvious blood in her stool, then she should be seen. Otherwise, I would see her veterinarian again or seek a second opinion. It is not normal for her to have ongoing GI issues. There are a variety of fecal and blood tests that can be used to help reach a diagnosis. A diet trial could also be beneficial. I hope this information helps and I am available if you wish to do a consultation.

My dog has had blood in stool for several days, what can I do?

These signs could be compatible with a colitis, which is an inflammation of the last part of the colon, usually related to dietary indiscretion. As a first approach, I would suggest to start feeding with a bland diet based on boiled chicken and rice in small portion every 6 hours for the following 48hours. Then gradually reintroduce the normal diet over 5 days. I would definitively recommend a veterinary check up if the signs persist or you notice vomiting, lethargy or inappetence.

My dog has dark, pudding-like, bloody diarrhea with mucus. What to do?

As long as he is otherwise well I would restrict jim to a bland diet such as boiled chicken and brown rice and add some pumpkin to restore normal bowel movement. Probiotics are also very helpful (natural yogurt if you can't source fortifora). Any lethargy, vomiting or reduced appetite would indicate the need for a vet check.

Why is my 9-week-old puppy's poop bloody with mucus? Should I worry?

Thank you for contacting Petco Pet Education Center, formerly Petcoach with your question about Kaiya. Poor girl. Blood in the poop can be caused by intestinal worms, a stomach illness, sudden change in diet, eating something rotten, a foreign body, or a severe illness like parvo. Because poop in the poop can have some very serious causes and it's been going on for a few days, it's time to see the vet. The vet can diagnose what is causing it and can treat her. I hope this helps!

My dog has a tiny pink blood drop in her poop, but acts normal. Why?

The drops of blood may be due to a little stress or inflammation in the colon. You can try a bland diet for 3-5 days to see if it helps. If not, have her seen by your vet. You should also submit a stool sample to your veterinarian to rule out intestinal parasites (worms).
