Cane Corso Diarrhea And Not Eating: Causes + What To Do 

Cane Corso diarrhea and not eating are symptoms that sometimes occur together. Loss of appetite or a dog not eating is a decrease in interest in food or a complete refusal to eat. It is an unusual dog behavior,  and raises concern especially when accompanied by other concerning symptoms such as diarrhea.

While diarrhea is common in Cani Corsi, it is important to understand what causes these two symptoms and when to seek veterinary care.

We outline the potential causes of Cane Corso diarrhea and not eating, along with the associated symptoms and when to seek help. 

Here’s why Cane Corso diarrhea and not eating occurs

Cane Corso diarrhea itself can lead to loss of appetite and a Cane Corso not eating. These symptoms  commonly occur together, and can be due to a number of illnesses and health issues which include diet change, illness, gastrointestinal infection, poisoning, stress, and medication side effects.  

Cane Corso diarrhea and not eating or loss of appetite are symptoms of a condition, rather than conditions in themselves.

Causes of Cane Corso diarrhea and not eating

A Cane Corso not eating or loss of an appetite is a common symptom of a Cane Corso suffering from diarrhea. A Cane Corso may experience both diarrhea and not eating as a result of an underlying condition. 

The possible causes of Cane Corso diarrhea and not eating are:

Underlying illness 

Diarrhea and not eating can be symptoms of a wide range of illnesses in Cani Corsi, including viral or bacterial infections, gastrointestinal disorders, and systemic diseases.

There are many factors that can cause a Cane Corso to not eat when they are ill, which include pain, nausea, digestive problems, and emotional distress.

Pain due to an illness can cause a Cane Corso to avoid eating or drinking. In addition to this, many illnesses can cause nausea which can make them feel too sick to eat.

Digestive problems due to illnesses such as vomiting or diarrhea can also lead to a lack of appetite and emotional distress experienced when they are ill can cause them to also lose their appetite.

Gastrointestinal infection

Gastrointestinal infection by bacteria, intestinal parasites, or viruses can cause Cane Corso diarrhea and loss of appetite.

Gastrointestinal infections can cause a Cane Corso to lose its appetite due to nausea, vomiting, diarrhea, and discomfort. These symptoms can lead to a loss of appetite in the dog.

Change in diet

A change in your Cane Corso’s diet can cause diarrhea and refusal to eat due to food intolerance or allergy, an upset stomach, and stress.

This is because it takes time for your Cane Corso’s stomach to adjust to the new food and a sudden change to a new food may cause diarrhea. 

Cani Corsi are also sensitive to changes in their routine and environment, and a sudden change in diet can be stressful. 

The stress can lead to digestive upset which causes diarrhea including other symptoms and a Cane Corso not eating due to :

  • Taste preference: Cani Corsi have preferences for certain flavors and textures of food, and if their new diet is not appealing to them, they may refuse to eat it.
  • Digestive issues: Switching to a new diet can cause digestive upset, such as diarrhea or constipation, which can cause a Cane Corso to feel sick and not want to eat.
  • Food allergies or intolerance: Some Cani Corsi may have allergies or intolerances to certain ingredients in their new food, which can cause gastrointestinal upset and loss of appetite.

If you are planning to change your Cane Corso’s diet, it is important to do so gradually over a period of several days to allow their digestive system to adjust. 


A stressed Cane Corso also experiences diarrhea including not eating, which may appear at the same time. 

Stress can cause a Cane Corso to lose its appetite in different ways. One way that stress can affect a Cane Corso’s digestive system is by causing nausea, stomach discomfort, and other digestive issues. 

This can lead to a loss of appetite as they associate food with discomfort or they may simply not feel hungry.

Stress can cause changes in the Cane Corso’s hormone levels, particularly the stress hormone. Elevated levels of the stress hormone can cause a decrease in appetite. 

Chronic stress can also suppress the immune system, leading to other health problems that can further affect their appetite. In addition to this, stress can lead to depression or anxiety, which can also cause a loss of appetite in Cane Corsos.

Stress and anxiety also cause a variety of symptoms including pacing, licking, drooling, yawning, crying, barking, and hiding.

Stress can come from a variety of sources such as a change in their environment or routine, new people or pets, loud noises, and other fear-related stressful situations.

Toxin ingestion

Poisoning in Cani Corsi can lead to a range of symptoms, including diarrhea and not eating. This is because many poisons can cause gastrointestinal upset and also affect a Cane Corso’s appetite.

Loss of appetite can happen because of:

Nausea and/or vomiting: Many poisons can cause nausea or vomiting. When a dog feels sick, they may refuse to eat or drink.

Mouth ulcers and irritation: Certain toxins can cause ulcers or irritation in a Cane Corso’s mouth. This can make it painful for the dog to eat or drink.

Organ damage: Some toxins may cause damage to a Cane Corso’s liver, kidneys, or other organs which can lead to a loss of appetite, as well as other symptoms.

Neurological problems: Some poisons can cause neurological symptoms such as seizures or tremors which can make it difficult for a Cane Corso to eat.

A Cane Corso may accidentally ingest toxic substances such as household cleaners, contaminated food or water, pesticides, insecticides, poisonous plants, or human medications, which can cause diarrhea, loss of appetite, and other symptoms.

Side effects of medication 

Medications can sometimes cause side effects in Cani Corsi, including diarrhea and refusal to eat. 

Many medications can cause gastrointestinal upset, including nausea, vomiting, and diarrhea, which can lead to a decreased appetite. 

The taste or smell of the medication can also be unpleasant, making a Cane Corso reluctant to eat.

Some medications also affect a Cane Corso’s sense of taste or smell, altering the way food tastes or smells, which can reduce their desire to eat. 

A Cane Corso’s mood and behavior can also be affected by some medications which lead to a decrease in appetite as a result of anxiety or depression.

Cane Corso diarrhea and not eating: What to do

If your Cane Corso  is experiencing both diarrhea and not eating, it is important to seek veterinary care as soon as possible. 

Here are  other signs that indicate that you should see a veterinarian immediately:

Severe or bloody diarrhea: If your Cane Corso’s diarrhea is severe or if there is blood or mucus in the stool, this could be a sign of a serious underlying condition and requires immediate veterinary attention.

Other symptoms: Other symptoms may accompany diarrhea and not eating, such as vomiting. If your Cane Corso is vomiting along with diarrhea, this can lead to dehydration and other complications. This requires immediate medical attention. 

Other symptoms to look out for include lethargy, breathing difficulties, signs of pain or discomfort, fever, and signs of dehydration, such as a dry nose or mouth and sunken eyes.

Suspicion poisoning: If you suspect that your Cane Corso  has been poisoned, it is important to seek veterinary care immediately.

If your Cane Corso  is a puppy or an older dog: Puppies and older are generally more vulnerable than healthy adult Cani Corsi so delaying treatment could result in their condition worsening or becoming more difficult to treat. Therefore, it is essential to seek immediate medical care.
