DOGS AND CATS WITH ACUTE DIARRHEA | WHEN SHOULD THEM BE TAKEN TO THE EMERGENCY ROOM?
I. Why are dogs and cats prone to acute diarrhea?
Acute diarrhea in dogs and cats can stem from a variety of causes, ranging from simple digestive disorders to serious conditions such as Parvo, Canine Distemper, hemorrhagic gastroenteritis, or poisoning.
1. Sudden changes in diet.
Switching from one type of grain to another, or going from eating homemade to canned food… all of these can cause the digestive system to not have time to adapt.
2. Eating spoiled food or unfamiliar food.
Rice noodles, fresh milk, chicken bones, greasy food, and food that has fallen on the ground are common causes of acute diarrhea in dogs and cats .
3. Dangerous viral infection
-
Parvo (in dogs and cats)
-
Care (dog)
-
Feline enteritis (FPV)
This group of diseases causes bloody diarrhea, persistent vomiting, rapid dehydration, and can be fatal within 24–48 hours if not treated promptly at a nearby veterinary clinic in District 5 .
4. Intestinal parasitic infections
Hookworms, roundworms, flukes, or protozoan parasites (Coccidia, Giardia).
5. Poisoning
Sudden diarrhea accompanied by tremors, weakness, and drooling may be caused by dogs and cats ingesting poisons such as rat poison, cleaning products, or chemicals.
II. Signs and Symptoms of Acute Diarrhea in Dogs and Cats
Early recognition of symptoms allows pet owners to proactively address the issue and determine when to take their pet to a nearby veterinarian in District 5 for emergency treatment.
1. Persistent diarrhea
-
Loose, watery stools
-
Foamy mucus stool
-
Green, yellow, or black feces
If diarrhea occurs more than 3 times in 6 hours , close monitoring is necessary.
2. Bloody diarrhea
-
Bright red blood
-
Dark, foul-smelling blood
-
Mixed with an unusual foul odor.
This is a medical emergency because it could be Parvo or hemorrhagic enteritis.
3. Persistent vomiting
Vomiting more than 2–3 times per hour, with yellow foam or green fluid.
4. Dehydration
-
Dry nose
-
Skin loses elasticity
-
Sunken eyes
Severe dehydration in dogs and cats can be life-threatening within just a few hours.
5. Loss of appetite – lethargy – fever

III. When Should You Take Your Dog or Cat to the Nearest Veterinary Clinic in District 5 for Emergency Treatment?
Not all cases of diarrhea require emergency care, but if any of the following signs occur , you should take your pet to the nearest veterinarian in District 5 immediately:
1. Diarrhea lasting more than 6 hours and not improving.
This condition causes rapid dehydration, which can lead to shock.
2. Diarrhea with blood or black stools
This is a sign of intestinal bleeding — emergency medical attention is needed.
3. Diarrhea in dogs and cats under 3 months old.
Rejuvenation is extremely sensitive and can be fatal within hours.
4. Persistent vomiting
Vomiting and diarrhea occurring simultaneously => rapid electrolyte loss.

VI. Home Care for Dogs and Cats with Acute Diarrhea (Only Applicable When Permitted by a Veterinarian)
If the veterinarian determines it’s a mild case, you can care for your pet at home:
