Vomiting & Bloody Diarrhea in Dogs

Anytime your dog experiences pronounced diarrhea, bloody stools, vomiting or a drastic change in his appetite, you should seek medical attention without delay. Though there are a few benign causes of intestinal irritation, acute diarrhea can quickly lead to severe liver or kidney damage, circulatory collapse and even death if untreated. Here are some things you need to know about diarrhea and bloody stools in your dog.

Diarrhea, vomiting and bloody stools can cause your pet to experience dangerous dehydration, an electrolyte imbalance, blood sugar depletion and even death due to a circulatory collapse.


There can be many causes for intestinal symptoms, including bacterial, fungal, viruses such as Parvo, parasites, pancreatic insufficiency, protosozum and environmental or ingested toxins.



Always take your dog to the veterinarian at the first sign of bloody diarrhea or excessive vomiting, because the condition can be dire and even fatal if not treated immediately.


Symptoms of diarrhea include loose, watery, bloody or frequent liquid stools, sometimes odd-colored or mucus-filled.

Possible Benign Causes

If you have recently changed your puppy's or dog's diet, are in the process of moving or have experienced a drastic change in your living or emotional circumstances at home, it is possible that your dog's upset stomach may be stress-related or caused by the new food.

Always check with your veterinarian before changing your pet’s diet, medication, or physical activity routines. This information is not a substitute for a vet’s opinion.
