There are many causes of diarrhea in dogs, such as acute intestinal infections, viral enteritis, poisoning diarrhea, etc. The following are the most common causes:


Dogs can often get parasites through sick dog feces, fleas, mosquitoes, etc. Common parasites that can cause diarrhea include roundworms, hookworms, and flukes. wire. Roundworms, whipworms, and hookworms can be transmitted through feces. When dogs come into contact with other dogs’ feces while walking, the eggs of roundworms in the feces will enter the dog’s body and cause an infection.

Tapeworm eggs are excreted in the feces; if the flea eats feces containing tapeworm eggs, the eggs will hatch in the flea’s body. When a dog accidentally ingests fleas infected with tapeworms, tapeworm larvae live on the wall of the dog’s small intestine. Dogs infected with parasites may have loss of appetite, vomiting, dysentery, stunted growth, a dull coat, and even blood and mucus in their stools.


gastroenteritis Gastroenteritis is an inflammation of the lining of the digestive tract, which can be divided into two types: chronic gastroenteritis and acute gastroenteritis. Under normal circumstances, most dogs develop acute gastroenteritis. Consuming spoiled food or water and other foreign objects such as plastic bags can lead to acute gastroenteritis.

Most dogs with acute gastroenteritis will present with vomiting, sunken eye sockets, abdominal pain, diarrhea, and a loss of appetite. Symptoms of chronic gastroenteritis may be less obvious, such as loss of appetite, listlessness, vomiting, and hiccups in dogs, which may be indicative of chronic gastroenteritis.

Viral enteritis

Common viral enteritis includes canine viral enteritis, canine parvovirus, coronavirus, and minor deoxyribonucleic acid virus.

Parvovirus disease in dogs

Small dogs are divided into enteritis and myocarditis, which are common in puppies from weaning to 90 days of age. Dogs with inflammatory bowel disease in the early stages have a fever—the body temperature can even reach over 40 degrees—frequent vomiting, severe diarrhea, straining, and passing stools with dark red blood and a bad smell. This type of myocarditis is more common in 40-day-old puppies, presenting often with shortness of breath and heart failure, some with mild diarrhea, which can lead to short-term death.

Small deoxyribonucleic acid

virus After the virus infects the intestinal tract, it can cause severe enteritis, which is common in puppies between 10 and 12 weeks. Symptoms include intense vomiting, diarrhea, blood in the stool in severe cases, and a foul odor. The dog should be dehydrated before being shocked.

How to treat dogs when they have diarrhea

For everyone’s convenience, here are some guidelines for treating diarrhea in dogs:

  • Do not eat any solid food for 24 hours.
  • After stopping eating for 24 hours, give a lighter food first, such as a small amount of chicken porridge, oatmeal, rice, or bread. Drinking water should be provided as usual unless vomiting occurs.
  • If stools return to normal after two to three days of light diet therapy and monitoring, a normal diet can be resumed.
  • If your dog vomits, take the following measures:
  • Do not eat any solid food for 24 hours.
  • After the fasting period, the supply of drinking water was resumed.
  • Six to twelve hours after resuming water intake, if vomiting is not present, the following diet can be offered, e.g., small amounts of chicken, porridge, oatmeal, or bread.
  • More water. Rehydrate dogs with diarrhea to prevent dehydration. When dogs have an appetite, they can also use oral rehydration salts (ORS), which are easy to use, safe, and effective for diarrhea caused by a variety of causes.If there is no rehydration salt, it can be replaced with salt water and sugar, i.e., 500 ml of water + 20 grams of sugar + 2 grams of refined salt. It can also be replaced with a saline solution, i.e., 500 ml of rice water + 2 grams of fine salt. Let the dog drink freely; if the dog cannot drink by himself, he can feed the dog.

For dyspeptic diarrhea

diarrhea caused by indigestion. For diarrhea caused by indigestion, as long as the dog has a good appetite and a normal mental state, it is recommended to use a specific dog diarrhea medication, which can usually be purchased at a pet store or pet hospital.

If you cannot use dog-specific diarrhea medications, you can use drugs such as Mamiai, lactomycin, and yeast tablets. Mix with dog food and feed, then fast for a day, but make sure to give the dog water to avoid dehydration, and do not overfeed after feeding. If your dog has had diarrhea for more than two days, seek medical attention immediately.

Oral dose:

  • Lactobacillus, 1 to 2 grams per kilogram of body weight, 3 times a day;
  • Mommy Love: 1 pack each time, 2 times a day (refer to dosage for children);
  • Yeast tablets: 8-12 grams/kg body weight, 3 times a day;

Diarrhea caused by acute and chronic

gastroenteritis Commonly used anti-inflammatory drugs include injectable gentamicin (which can be taken orally), usually 80,000 units in 2 ml. Dosage may refer to about 10,000 units per kilogram of body weight taken orally twice a day.

It should be noted that after feeding gentamicin for half an hour each time, you should give some drugs to digest live mushrooms, such as Gudeng probiotics, lactomycin, and mamiai, to support treatment. Feed your dog for a day and make sure he drinks enough water.

If the symptoms of diarrhea do not improve after taking the medicine, seek medical advice promptly. If gentamicin is not available, you can also feed your dog Smecta, 250–500 mg per kilogram of body weight, twice a day; Smecta can remove the contents of the dog’s stomach from the body and has an anti-diarrheal effect.

Seek prompt medical attention.

The above treatment options are only for dogs with mild indigestion or diarrhea. For viral or severe diarrhea, such as loose and bloody stools, you should seek medical attention promptly. If your dog has diarrhea that is accompanied by listlessness, loss of appetite, intense vomiting, increased or decreased body temperature, and parasites or viruses are suspected as the cause, you should seek medical attention and treat your dog as soon as possible to avoid slowing down the disease.

You can take a sample of your dog’s stool and bring it to the pet hospital for testing so they can prescribe the right medication. If your dog has not been vaccinated against the virus before, you should pay attention to its diarrhea.


Due to the different physical characteristics of dogs, the use of medication for dogs should be combined with the actual situation. I hope everyone finds the article How to Treat When Dogs Have Diarrhea useful, and I will continue to share dog health content with you in the future.
