Why Do Dogs get Diarrhea - Reasons for Soft Stool, Night Time Diarrhea and Urgency to Defecate

Updated: May 2, 2023

Diarrhea is a common condition that affects many dogs from time to time. It is characterized by loose or watery stools and can range from mild to severe. Understanding the causes of diarrhea in dogs is important because it can help pet owners take appropriate steps to prevent and treat the condition. There are several reasons why dogs may experience diarrhea, including dietary factors such as eating highly processed commercial diets or lack of variety in their diet, compromised gut microbiome, parasites, bacterial infections, stress and anxiety, medication side effects, and underlying health conditions like inflammatory bowel disease or pancreatic insufficiency. In this article, we will explore these causes in more detail and discuss ways to prevent and manage diarrhea in dogs.

Eating Highly Processed Commercial Diet


Many dog owners opt for highly processed commercial diets for convenience and affordability. These diets are typically made up of low-quality ingredients such as meat by-products, corn, and wheat, which are then heavily processed to create kibble or canned food. These diets often contain artificial preservatives, colors, and flavors, which can be harmful to dogs in the long term.




Negative impact of highly processed commercial diets on the digestive system

The digestive system of dogs is designed to digest and absorb nutrients from whole foods, such as meat, vegetables, and fruits. However, highly processed commercial diets lack the essential nutrients that dogs need for optimal health, and the low-quality ingredients can cause inflammation and damage to the gut lining. Over time, this can lead to a compromised gut microbiome and digestive issues, such as diarrhea.


Link between highly processed commercial diets and diarrhea in dogs

Studies have shown that dogs who consume highly processed commercial diets are more likely to develop diarrhea than those who consume a whole food-based diet. The lack of essential nutrients, high levels of carbohydrates, and artificial additives in commercial diets can disrupt the balance of bacteria in the gut and lead to inflammation, which can cause diarrhea. Switching to a whole food-based diet can help improve the digestive health of dogs and reduce the likelihood of developing diarrhea.

Constant Exposure to the Exact Same Food Ingredient and Lack of Diet Variety


How constant exposure to the same food ingredient can lead to diarrhea

Dogs who are constantly exposed to the same food ingredient in their diet may develop an intolerance or sensitivity to that ingredient over time.

This can lead to inflammation in the digestive tract, which can cause diarrhea. Additionally, dogs who do not have enough variety in their diet may not be getting all of the necessary nutrients they need for optimal health, which can also contribute to digestive issues like diarrhea.


Role of food sensitivities and allergies in causing diarrhea

Food sensitivities and allergies can also play a role in causing diarrhea in dogs. If a dog is allergic or sensitive to a certain food ingredient, their body may have an inflammatory response to that ingredient, leading to diarrhea. Common allergens for dogs include beef, dairy, chicken, and wheat.


Discussion of the importance of rotating dog food ingredients to prevent diarrhea

To prevent diarrhea caused by constant exposure to the same food ingredient, it is important to rotate the ingredients in a dog's diet regularly. This can help prevent the development of food sensitivities and allergies, as well as ensure that the dog is getting a variety of nutrients for optimal health. When introducing new ingredients, it is important to do so slowly and monitor the dog's response to ensure they do not have an adverse reaction. Additionally, it is important to choose high-quality, whole food-based diets that are free from artificial additives and preservatives.

Compromised Gut Microbiome


Gut microbiome and its role in digestive health

The gut microbiome refers to the complex community of microorganisms that live in the digestive tract of dogs. These microorganisms play a crucial role in maintaining digestive health by aiding in the breakdown and absorption of nutrients, synthesizing vitamins and other beneficial compounds, and protecting against harmful bacteria and pathogens.



The ways in which a compromised gut microbiome can lead to diarrhea

When the balance of microorganisms in the gut is disrupted, it can lead to a compromised gut microbiome, which can result in digestive issues such as diarrhea. This can be caused by a number of factors, including exposure to toxins, stress, illness, and antibiotic use, which can kill off beneficial bacteria in the gut and allow harmful bacteria to proliferate.


Strategies for promoting a healthy gut microbiome in dogs

There are several strategies that pet owners can use to promote a healthy gut microbiome in their dogs. One important step is to feed a high-quality, whole food-based diet that is rich in fiber and beneficial nutrients.

Probiotic and collagen supplements can also be helpful in restoring beneficial bacteria in the gut, particularly after a course of antibiotics or other illness.

Additionally, reducing stress and providing plenty of exercise and mental stimulation can help support a healthy gut microbiome in dogs.



Parasites


Common parasites that can cause diarrhea in dogs

Parasites are a common cause of diarrhea in dogs, and there are several types that can infect them. Some of the most common parasites include Giardia, Cryptosporidium, Coccidia, and hookworms. These parasites can be contracted through contact with contaminated feces or soil, ingestion of contaminated water or food, or from other infected animals.


How parasites are contracted and diagnosed

Parasites can be diagnosed through a fecal examination by a veterinarian, which involves examining a stool sample for the presence of parasite eggs or other signs of infection. Dogs that are infected with parasites may exhibit symptoms such as diarrhea, vomiting, weight loss, and lethargy. It is important to seek veterinary care if these symptoms are present, as parasites can cause serious health issues if left untreated.


Treatment and prevention of parasitic infections in dogs

Parasitic infections can be treated with medication prescribed by a veterinarian. The type of medication will depend on the type of parasite and the severity of the infection. In addition to treatment, prevention is also important. This includes regular deworming and fecal examinations, as well as proper sanitation practices such as cleaning up after your dog and providing clean drinking water. It is also important to limit exposure to other infected animals and to avoid allowing your dog to drink from standing water sources such as ponds or streams.

Bacterial Infection


Common bacterial infections that can cause diarrhea in dogs

Bacterial infections are a common cause of diarrhea in dogs, and there are several types of bacteria that can cause infection. Some of the most common bacterial infections in dogs include Salmonella, Campylobacter, and E. coli. These bacteria can be contracted through ingestion of contaminated food or water, or through contact with contaminated feces or soil.


How bacterial infections are contracted and diagnosed

Bacterial infections can be diagnosed through a fecal examination or blood test by a veterinarian. The veterinarian may also perform a physical examination to check for other signs of infection. Dogs that are infected with bacteria may exhibit symptoms such as diarrhea, vomiting, fever, and dehydration. It is important to seek veterinary care if these symptoms are present, as bacterial infections can cause serious health issues if left untreated.


Treatment and prevention of bacterial infections in dogs

Bacterial infections can be treated with antibiotics prescribed by a veterinarian. The type of antibiotic will depend on the type of bacteria and the severity of the infection. In addition to treatment, prevention is also important. This includes practicing proper sanitation and hygiene, such as washing hands after handling animal feces or preparing food, and keeping food and water sources clean and free from contamination. Regular veterinary check-ups and vaccinations can also help prevent bacterial infections in dogs.

Other Causes of Diarrhea in Dogs


Stress and anxiety

Stress and anxiety can also be a cause of diarrhea in dogs. Dogs that are in a stressful environment or are experiencing anxiety may exhibit symptoms such as diarrhea, vomiting, loss of appetite, and lethargy. Stressful situations such as traveling, changes in routine, or being left alone for long periods of time can trigger these symptoms. Treatment for stress and anxiety may involve behavior modification techniques, medication, or a combination of both.


Medication side effects

Some medications can have side effects that include diarrhea in dogs. Antibiotics, pain relievers, and nonsteroidal anti-inflammatory drugs (NSAIDs) are examples of medications that may cause diarrhea in dogs. It is important to follow the prescribed dosage and monitor your dog for any adverse reactions. If your dog experiences diarrhea or other symptoms, it is important to contact your veterinarian.


Inflammatory bowel disease

Inflammatory bowel disease (IBD) is a condition in which the digestive tract becomes inflamed. This can lead to diarrhea, vomiting, weight loss, and decreased appetite in dogs. The cause of IBD is not well understood, but it is believed to be related to an abnormal immune response to the bacteria in the gut. Treatment for IBD may involve changes in diet, medication, or a combination of both.


Pancreatic insufficiency

Pancreatic insufficiency is a condition in which the pancreas is unable to produce enough digestive enzymes to properly break down food. This can lead to diarrhea, weight loss, and a lack of energy in dogs. Treatment for pancreatic insufficiency may involve enzyme replacement therapy and changes in diet. It is important to seek veterinary care if you suspect that your dog may be suffering from any of these conditions.


Conclusion


Main reasons for dogs suffering from diarrhea

In summary, there are many reasons why dogs can get diarrhea, including improper diet, changes in diet, infections (viruses, bacteria, and parasites), stress and anxiety, medication side effects, inflammatory bowel disease, and pancreatic insufficiency.


Final thoughts on preventing and managing dog diarrhea

Preventing and managing dog diarrhea requires several strategies, including feeding high-quality food, providing adequate clean drinking water, maintaining good hygiene and environmental cleanliness, timely vaccination and deworming treatments, and reducing stress and anxiety. Additionally, seeking veterinary care is crucial if your dog experiences persistent or severe diarrhea, as timely treatment can prevent more serious health problems from arising. With proper care and attention, most cases of dog diarrhea can be successfully managed and resolved.
