What is Acute Sudden Diarrhea?

Diarrhea can last for several days to several weeks, and can even last a month without proper veterinary care; if your dog has diarrhea for under a day there may be no real need for concern. It will be important to watch over him; however, dogs can get this illness from time to time. If it does persist, it will be important to contact the veterinarian to see precisely what is causing his upset stomach.

Abnormally frequent loose and runny stools are known as diarrhea, and acute (sudden) diarrhea is characterized by one cause with a sudden onset.

Symptoms of Acute Sudden Diarrhea in Dogs

Symptoms of diarrhea are straightforward and common at times; however, if your dog has black diarrhea, then he could be having internal bleeding and must be seen by a veterinarian immediately. Symptoms of acute (sudden) diarrhea include:

  • Very loose stools, almost liquid-like
  • Flatulence
  • Mucus in the stool
  • Straining when defecating
  • Lethargy
  • Dehydration
  • Fever
  • Malaise 
  • Loss of appetite
  • Loss of weight


In some cases of diarrhea, the underlying cause may be parasites. Dogs can get parasites from eating things they shouldn’t eat, such as soil or feces. They can also get parasites if they accidentally eat food or drink water that is contaminated. Puppies can become infected from their mother. Parasites that can give your dog diarrhea are:

  • Roundworm
  • Whipworms
  • Hookworms
  • Giardia
  • Coccidia
  • Salmonella
  • E.Coli

Causes of Acute Sudden Diarrhea in Dogs

Certain types of breeds can come down with diarrhea more than others, such as the German Shepherds, due to a higher percentage of this breed having pancreas issues. Also, young puppies are more likely to get diarrhea due to parasites than adult dogs. Acute (sudden) dog diarrhea can be caused by several factors. These causes can be:

  • Sudden dietary changes
  • Intolerance to certain foods
  • Eating spoiled food
  • Parasites
  • Poisonous substances that are ingested
  • Ingestion of an object
  • Reaction or allergy to a substance
  • Infection, either bacterial or viral
  • Inflammatory bowel disorder
  • Liver disease
  • Kidney disease
  • Cancer of the digestive area
  • Medication
  • Digestive area tumors
  • Colitis
  • Stress
  • Gastrointestinal disorder or stress

Diagnosis of Acute Sudden Diarrhea in Dogs

If your dog has diarrhea for more than 24 hours, it is time to take him to the veterinarian. Be sure you have provided and are continuing to provide fresh water so he doesn’t become dehydrated. Once you get the dog to the veterinarian, the doctor will ask you what the onset was, if he ate anything different, or a generalized history of the last few days. Then you will be asked to tell the vet about your dog’s history if he doesn’t have his chart. 

The veterinarian will then assess your fur baby for underlying medical disorders or abnormalities. He may perform imaging methods, an ultrasound of the abdomen and lower intestines, cultures, a biopsy, endoscopy, and any other tests he feels he needs to administer.

Treatment of Acute Sudden Diarrhea in Dogs

Many acute and sudden dog diarrhea episodes can be monitored by you at home. Observing your companion during the time he has the loose and runny stools is crucial; you must be sure he is drinking water to avoid becoming dehydrated. In terms of eating, it is a good idea to hold food from him for twelve hours to allow his GI tract to rest and heal. Gradually add boiled chicken and rice to his diet, and if you prefer, you can give him a probiotic supplement. The bland diet should be fed to him for a few days. Avoid all medications or over-the-counter drugs unless you have been to the veterinarian and she has suggested a medication be given to him.

Recovery of Acute Sudden Diarrhea in Dogs

In terms of recovery, once the veterinarian has made an accurate diagnosis, he will instruct you on what to do at home. If the diarrhea is caused by a more serious, underlying disorder, recovery and management may vary depending on what the diagnosis is.

Keep a watchful eye over your loved one for any change in behavior or symptoms, and contact your veterinarian if you become concerned or have any questions.

For the future, prevention of diarrhea can be quite successful. In order to help keep diarrhea at bay, you should keep up-to-date with vaccines, keep the dog away from trash, spoiled food, or from eating dirt and soil, do not allow your dog to eat feces of any kind or drink dirty “puddle” water, and if you plan on changing your dog’s diet, do so very gradually. All of these tips can help you stay out of the veterinarian office and remain healthy in the comfort of your own home.

my 3 year old bulldog mixed came down with diarrhea 2 days ago, never before had she had this. She does like to chew on things, but I did not find any evidence of that. Yesterday she was much better and stool was a bit firmer than the puddle of the day before, but today it's back to a puddle with what appears to be mucas. She is drinking water normally, and playing, and does not appear to be in pain at all.

Thank you for your email. There are many reasons that a dog might get diarrhea, including parasites, dietary indiscretion, or an intestinal infection. Since Chloe's diarrhea doesn't seem to be resolving, it would be a good idea to have her seen by your veterinarian, as they can look at her, do any necessary testing or treatments that she may need, and get her feeling back to normal quickly!

Thank you for your email. There are many reasons for diarrhea in dogs, including dietary indiscretion, parasites, intestinal infection, or food intolerance. If her diarrhea doesn't clear up in 25 hours with the fasting that you gave her, it would be best to have her examined by her veterinarian, as they can examine Jessie, determine what might be going on, and give any treatment that might be necessary. I hope that she recovers uneventfully.

3 out of 4 dogs at home now have diarrhea. Im freaking out! We thought it was a behavioral thing with 1st dog, then maybe 2nd one was craving attention (he pooped in his bed after 10 minutes of night night, then again after cleaning him up, did it again. Now tonight (4 days since 1st one had issues), our 3rd dog just had an episode in our bed.

Thank You!

I have a 10yr old golden retriever that suddenly has diarrhea. Everything else is normal. It has been 2 days and the now the stools are showing signs of getting more solid. He is drinking plenty of water and eating has not changed and he is still running around the yard as usual. No weight loss or lethargy

Diarrhoea may occur for a number of reasons and may resolve without intervention, other times diarrhoea is caused by something more serious like infection or another cause and requires treatment; if Miken stool is firming up, it is a good sign, try adding a little plain canned pumpkin to up the fibre intake. If Miken still has diarrhoea after three days I would recommend visiting your Veterinarian for an examination. Regards Dr Callum Turner DVM

Vomiting and Diarrhoea may occur in unvaccinated puppies due to parvovirus which is a highly fatal disease if not treated (symptomatic and supportive) immediately. I would take Brucey to your Veterinarian for a check and possibly for fluids if dehydrated. Other possible cause may be due to other infections, parasites, foreign bodies, food intolerance or poisoning. Regards Dr Callum Turner DVM
