What does vomiting and bloody diarrhea in pet dogs mean?
Is it a puppy? You need to simultaneously observe body temperature, nose, and mental state. Puppies are especially susceptible to parvovirus and distemper, which are severe and aggressive diseases. These illnesses require stool tests or blood tests and must be treated promptly in cooperation with a veterinarian. Don't delay.

Have you fed any poultry bones? Quickly measure the temperature first; this might be parvovirus. Compare the following symptoms: Canine parvovirus symptoms usually manifest in two clinical types: hemorrhagic enteritis type and non-suppurative myocarditis type. Dogs infected with canine parvovirus suffer from diarrhea. 1. Depression, vomiting, sudden diarrhea, loss of appetite, refusal to drink water, dehydration, weakness 2.
Because of severe dehydration, normal activity in the morning but lethargic at night 3. Severe gastroenteritis causes frequent vomiting 4. Early-stage feces are loose paste-like; as the condition progresses, feces appear like ketchup or coffee color, with a fishy stench, irregular defecation, and urgency symptoms. 5. Body temperature can exceed 40℃ Hemorrhagic enteritis type canine parvovirus symptoms: mainly affect puppies aged 2–6 months, with an incubation period of 7-14 days.
The sick dog generally falls ill suddenly, often after a recent environment change (like a newly purchased puppy), with triggers including bathing or overeating. Initial signs include depression, anorexia, fever with temperatures above 40℃, soft stools or mild vomiting, dry nasal planum, early conjunctival hyperemia, later pallor, vomiting that starts with food material then changes to mucus and yellow-green fluid, progressing to frequent vomiting and severe diarrhea. At first, stools are grey, yellow, or milky white with jelly-like mucus, then become ketchup or coffee-colored with a fishy stench, irregular defecation, and urgency symptoms. The heart rate also increases, usually >180 bpm, sometimes over 240 bpm, almost uncountable.
After bloody stools, the sick dog shows sunken eyes, dry nasal planum, weakness throughout the body, significant weight loss; later, vomit appears yellow-green or blood-stained, sometimes dry heaving occurs, followed rapidly by projectile diarrhea starting yellow or grey-yellow with large amounts of mucus or pseudomembranes, then ketchup or millet soup-like stools with particularly foul fishy odor. The dog rapidly loses weight, dehydrates, eye sockets sink, skin elasticity decreases, and capillary refill time lengthens.
The sick dog quickly dehydrates, wastes away, has sunken eyes, disheveled coat, inelastic skin, cold ears, nose and limbs, severe depression, shock, and death. Most dogs have elevated temperatures around 40°C, but some never have a fever. Dogs often die around 3 days after diarrhea due to dehydration, electrolyte imbalance, and acidosis. From mild to severe symptoms generally takes no more than 2 days; the entire course usually doesn't exceed one week.
If the above symptoms are excluded and it is just general gastroenteritis causing diarrhea and vomiting without severe impact, normal mental state, little difference from usual, and stools with no foul smell and usual texture, it’s recommended to use Smecta, Gudeng probiotics, Mami Ai, or lactobacillus tablets to regulate the gut flora, giving one-third of the Mami Ai dose three times daily.
If diarrhea continues now, fasting is needed, water is allowed, fasting for 12 hours. Resume feeding when diarrhea stops. For dog food, feeding prescription diets that aid intestinal digestion can greatly help treat dog gastroenteritis. Also beware of distemper; early symptoms show dog temperatures reaching 39.5-41°C, poor appetite, depression, watery nasal and eye discharge, sneezing, and diarrhea.
Within 2–14 days, body temperature rises again, coughing, purulent nasal discharge, and purulent eye discharge appear—signs of mid-stage distemper. The incubation period is 3-9 days. Symptoms vary depending on virulence, environment, age, and immunity. Distemper begins with fever lasting 1-3 days that then subsides, resembling a cold recovering. But a few days later, fever returns and lasts variably.
Signs include tearing, conjunctival redness, eye discharge changing from watery to sticky purulent, thickened foot pads, dry nasal planum, nasal discharge starting serous then purulent, initially dry cough progressing to wet cough and breathing difficulties. Therefore, first check body temperature, and if it is above 39°C with decreased appetite and mental state, it is advised to buy test strips for home testing.
