Dog Bloody Stool and Vomiting

1 Overview

Causes and Solutions for a Dog’s Bloody Stool and Vomiting

1. Eating too much

Dogs are very greedy animals; if the owner is not careful at home, they sniff and eat everywhere, and if the owner gives in when the dog acts cute, the dog eats too much. Also, vigorous exercise right after eating triggers vomiting. If daily life and diet are not controlled, the dog may suddenly vomit. In severe cases both sudden vomiting and bloody stool appear, these two symptoms together.

2. Gastroenteritis

Dog gastroenteritis is acute or chronic; acute enteritis’s main symptoms are abdominal pain, diarrhea, fever, and toxemia; chronic enteritis shows repeated vomiting and loose stool, the stool is watery with foul odor, and in severe cases bloody stool. Whether acute or chronic, diagnosis should be made at a hospital, then diet controlled to reduce gut burden. Use probiotics to regulate the gut until full recovery.

3. Distemper and parvovirus

Canine parvovirus has two forms: myocardial and enteric. Myocarditis mostly occurs in puppies, with pale mucous membranes and difficulty breathing as main symptoms; the enteric form shows vomiting and diarrhea as main symptoms. Stool is yellow or grayish-white with much mucus early, becoming watery and blood-mixed as the disease progresses; there are also obvious rhinitis and conjunctivitis, with nasal discharge, sneezing, coughing, and dry cracked nose.

4. Parasites

If deworming is long neglected, parasites may cause the dog to vomit and pass blood; the owner can check the last deworming time and whether there are worms in the stool. If there are worms, an internal deworming is fine.
