My dog has bloody diarrhea with white goo. What should I do?

Updated on September 23rd, 2025

My dogs have been pooping with a white goo. It then turned into diarrhea and one of them is now having blood mixed in it. They are not lethargic but was wondering what it could possibly be.

I am very sorry to hear that your dogs are experiencing these problems, I am sure it is very unsettling for you both. There are a number of potential causes of such clinical signs, including dietary indiscretion, pancreatitis, parasite infestation, infection, and ingestion of a toxin or poison.


Because you have only noticed these signs over the course of a few days I would continue to monitor them at home.

Rest their gastrointestinal tracts by holding back food for a few hours. Then you can continue with a bland and easily digested food of the boiled chicken breast and white rice diet and provide plenty of fresh water. I also find that boiled, mashed skinless sweet potato is helpful for diarrhea.

If they do not improve, has profuse vomiting or diarrhea, you notice fresh blood, they seems lethargic, in pain or depressed I would advise a trip to the veterinarian.

I would also consider a worming treatment if you have not done so in the last 4 months;
