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 Lethargic
When your dog is vomiting white foam and also acting lethargic, it could indicate a more serious underlying condition. Vomiting alone may result from mild stomach upset, but when combined with weakness or fatigue, it often suggests illness that needs prompt veterinary attention.

Dog Vomiting White Foam and Lethargic — Why It Happens
When vomiting white foam is paired with lethargy, it usually means the dog is experiencing more than just minor stomach irritation—often an infection, organ dysfunction, toxin ingestion, or gastrointestinal blockage is to blame. Dogs may seem listless, avoid food, or struggle to get comfortable, all signs that the body is fighting off illness.
Common Causes of Dog Vomiting White Foam and Lethargic
Pancreatitis
Pancreatitis is inflammation of the pancreas, often triggered by rich or fatty foods. It causes vomiting, abdominal pain, and profound lethargy.
Dogs with pancreatitis may vomit white foam or bile, appear bloated, and be reluctant to move.
This condition is painful and dangerous if untreated. It usually requires hospitalization, fluid therapy, and a special diet.

Gastrointestinal Obstruction
If your dog swallows a foreign object (like a sock or toy), it may block the digestive tract.
This leads to vomiting white foam and food, along with lethargy, restlessness, and signs of abdominal discomfort.
Obstructions can quickly become life-threatening. If you suspect this, seek emergency veterinary care.
Toxic Ingestion
Ingesting toxins such as human medications, cleaning products, certain plants, or spoiled food can lead to vomiting and systemic illness.
Lethargy, drooling, pale gums, and even seizures may follow depending on the toxin.
Always call your vet or a poison hotline immediately if you believe your dog ingested something dangerous.
Kidney or Liver Disease
Dogs with chronic kidney or liver disease may vomit white foam and appear very weak or tired.
These conditions impair the body’s ability to filter toxins, leading to nausea, weight loss, and disinterest in food.
Routine bloodwork is required to diagnose and monitor these diseases. Treatment often includes fluids, dietary changes, and medications.
Parvovirus (in Puppies)
In young or unvaccinated dogs, parvovirus is a deadly infection that causes vomiting, extreme lethargy, and bloody diarrhea.
Dogs with parvo rapidly become dehydrated and may vomit foam or bile as their gut becomes inflamed.
Immediate veterinary care is essential—this is a medical emergency.

What to Do If Your Dog Is Vomiting White Foam and Lethargic
Remove food and limit water intake for several hours to allow the stomach to rest—unless your dog is very weak or dehydrated.
Monitor closely for signs of worsening: continued vomiting, pale gums, or collapse require urgent care.
If mild symptoms improve, introduce small amounts of bland food such as boiled chicken and rice.
Keep your dog in a quiet, low-stress environment. Avoid exertion or heat exposure.
If there’s any uncertainty about your dog’s condition—or if they continue to vomit or act weak—call your veterinarian.
When to Call or Visit Your Vet
Contact your vet urgently if your dog:
Vomits white foam more than once or repeatedly
Shows signs of dehydration (dry gums, sunken eyes, poor skin elasticity)
Is unwilling to move, refuses food, or collapses
Has a known history of eating foreign objects or toxins
Is a puppy, senior dog, or has chronic medical conditions
Your vet may perform bloodwork, x-rays, or ultrasounds to identify the problem and start treatment quickly.
