It’s frightening to see an old dog pooping blood and refusing to eat. These symptoms can indicate a serious medical emergency and should never be ignored.
We outline the common causes of old dog pooping blood and not eating, what you can do at home, and when to seek veterinary help.
Old Dog Pooping Blood and Not Eating — Why It Happens
Blood in the stool and appetite loss in senior dogs can signal anything from intestinal inflammation to cancer or life-threatening infections. The digestive tract is sensitive, and in older dogs, even minor disruptions can lead to severe consequences. When eating stops and blood appears in the stool, it’s a clear sign the body is in distress.
Dog Vomiting White Foam and Loose Stool
If your dog is vomiting white foam and also passing loose stool, it typically points to digestive upset or gastrointestinal inflammation. While mild cases may resolve on their own, this combination can quickly lead to dehydration and requires careful monitoring.

Dog Vomiting White Foam and Loose Stool — Why It Happens
Vomiting white foam along with loose stool often indicates irritation of both the stomach and intestines. This may result from dietary indiscretion, viral or bacterial infections, parasites, or underlying conditions like pancreatitis. Dogs may seem tired, lose their appetite, or show signs of abdominal discomfort.
Common Causes of Dog Vomiting White Foam and Loose Stool
Dietary Indiscretion
Eating table scraps, garbage, spoiled food, or unfamiliar treats can upset your dog’s stomach.
This often results in vomiting foam and passing soft or runny stool as the body tries to eliminate the irritant.
While mild cases usually improve with rest and a bland diet, repeated episodes or worsening symptoms need veterinary care.
Viral or Bacterial Infections
Infections such as parvovirus, coronavirus, or bacterial gastroenteritis can cause severe vomiting and diarrhea.
White foam is often the first sign, followed by watery or loose stool, lethargy, and poor appetite.
Puppies and unvaccinated dogs are especially at risk. Prompt veterinary care is crucial to prevent dehydration and complications.
Intestinal Parasites
Worms like hookworms, roundworms, or giardia can disrupt the digestive tract.
Vomiting (especially on an empty stomach) and loose stool are common signs. You may even see worms or mucus in the stool.
Routine deworming and fecal testing help keep your dog parasite-free and reduce GI upset.

Pancreatitis
Pancreatitis causes inflammation of the pancreas and can lead to vomiting, diarrhea, and abdominal pain.
The vomit may be foamy if the stomach is empty, and the diarrhea can be greasy or loose.
Dogs with pancreatitis often need veterinary care, fluid support, and a low-fat diet to recover.
Food Intolerance or Allergy
Dogs may develop intolerance or sensitivity to certain proteins or ingredients in their food.
This can result in chronic or intermittent vomiting and soft stool, sometimes with mucus or mild blood.
An elimination diet or prescription food trial may be needed to identify the offending ingredient.
What to Do If Your Dog Is Vomiting White Foam and Has Loose Stool
Withhold food for 12 hours to allow the GI system to rest. Offer small amounts of water or ice chips to prevent dehydration.
After the fasting period, introduce a bland diet like boiled chicken and plain rice in small portions.
Monitor stool consistency and vomiting frequency closely. Avoid giving treats or switching foods suddenly.
If your dog shows signs of improvement, continue the bland diet for 2–3 days before transitioning back to regular food.
Do not administer human anti-diarrheal or anti-nausea medication unless directed by your veterinarian.
When to Call or Visit Your Vet
Contact your vet if your dog:
Vomits multiple times or has persistent diarrhea
Becomes lethargic, refuses water, or shows signs of pain
Has blood or mucus in stool
Is a puppy, senior dog, or has preexisting medical issues
Shows no improvement within 24 hours of home care
Your vet may perform blood tests, fecal exams, and imaging to identify the cause and recommend appropriate treatment.
