Inflammation of the Digestive System – Causes, Symptoms and Treatments
Summary
Digestive inflammation is a prevalent issue in dogs that can arise from various causes, such as infections, dietary indiscretions, food allergies, and chronic conditions like inflammatory bowel disease (IBD). This inflammation can affect different parts of the digestive system, leading to discomfort, pain, and potentially serious health issues. This article provides a detailed exploration of digestive inflammation in dogs, covering its types, causes, symptoms, and available treatments. It also highlights the role of diet, supplements, and natural herbal remedies, including adaptogens, in managing digestive inflammation. By understanding the mechanisms behind digestive inflammation and the most effective ways to address it, dog owners can help their pets maintain a healthy digestive system and overall well-being.
Digestive inflammation in dogs can manifest in various forms, depending on which part of the digestive system is affected. Understanding the different types of digestive inflammation is crucial for effective diagnosis and treatment.
Gastritis is the inflammation of the stomach lining, which can be acute or chronic. Acute gastritis is often triggered by dietary indiscretion, such as eating spoiled food or ingesting non-food items. Chronic gastritis can be linked to underlying conditions like Helicobacter pylori infection, prolonged use of NSAIDs, or chronic exposure to irritants. Symptoms of gastritis include vomiting, abdominal pain, and loss of appetite.
Gastroenteritis refers to the inflammation of both the stomach and intestines, resulting in symptoms like vomiting, diarrhoea, and abdominal pain. This condition can be caused by infections (bacterial, viral, or parasitic), food intolerances, toxins, or sudden dietary changes. Acute gastroenteritis is typically short-lived, while chronic gastroenteritis may persist or recur frequently.
Inflammatory Bowel Disease (IBD) is a chronic condition characterised by persistent inflammation of the digestive tract, particularly the intestines. The exact cause of IBD is not fully understood, but it is believed to involve an abnormal immune response to intestinal bacteria, food antigens, or other environmental factors. IBD can affect different parts of the digestive tract, including the stomach (gastritis), small intestine (enteritis), and colon (colitis). Symptoms of IBD include chronic diarrhoea, vomiting, weight loss, and abdominal pain. Management typically involves dietary modifications, immunosuppressive medications, and probiotics to support gut health.
Enteritis
Enteritis is the inflammation of the small intestine, which can result from infections, food allergies, or autoimmune conditions. It is a common component of gastroenteritis but can also occur independently. Enteritis leads to symptoms like diarrhoea, abdominal pain, and malabsorption of nutrients, which can result in weight loss and poor overall health. Chronic enteritis is often associated with conditions like IBD, where the inflammation persists over a long period and requires ongoing management.
Colitis is the inflammation of the colon (large intestine), which can be acute or chronic. It is often associated with stress, infections, food intolerances, or underlying conditions such as IBD. Colitis results in frequent, small-volume diarrhoea, often accompanied by mucus or blood. Dogs with colitis may also strain during defecation and exhibit abdominal discomfort. Chronic colitis can lead to long-term digestive issues and requires careful management through dietary changes, medications, and stress reduction strategies. In some cases, colitis may be a component of IBD, particularly when the inflammation is confined to the colon.
Causes of Digestive Inflammation
Food Allergies
Food allergies are a significant cause of digestive inflammation in dogs. When a dog’s immune system reacts to a specific food ingredient, it can cause inflammation in the digestive tract. Common allergens include animal proteins (such as beef, chicken, and dairy), certain grains, and artificial additives. Symptoms of food allergies can include vomiting, diarrhoea, gas, and abdominal discomfort, along with skin-related symptoms like itching and redness.
Infections
Infections caused by bacteria, viruses, or parasites can lead to acute or chronic digestive inflammation. Common pathogens include Helicobacter pylori, which can cause gastritis, and Giardia, a parasite that causes gastroenteritis. These infections often require prompt treatment to prevent further complications, including chronic inflammation and damage to the digestive tract.
Autoimmune Diseases
Autoimmune diseases occur when the immune system mistakenly attacks the body’s own digestive tissues, leading to chronic inflammation. Although inflammatory bowel disease (IBD) is not strictly an autoimmune disease but rather an immune-mediated inflammatory disease (IMID). Generally speaking, IMIDs are conditions in which chronic inflammation happens due to an atypical immune response in much the same way autoimmune diseases trigger a response. This condition can affect different parts of the digestive tract and requires long-term management to control symptoms and prevent flare-ups.
Dietary Indiscretion
Dietary indiscretion refers to the consumption of inappropriate foods or non-food items, which can irritate the digestive tract and lead to inflammation. Examples include eating garbage, spoiled food, or ingesting foreign objects like toys or bones. This can cause acute gastritis or gastroenteritis and may require veterinary intervention to prevent complications.
Chronic Inflammatory Conditions
Chronic inflammatory conditions such as IBD or pancreatitis can lead to ongoing digestive inflammation. These conditions often involve a complex interplay of genetic, environmental, and immune system factors. Management typically involves dietary changes, medications, and, in some cases, surgery to control symptoms and prevent flare-ups.
Symptoms of Digestive Inflammation
The symptoms of digestive inflammation in dogs can vary depending on the severity and underlying cause but generally include the following:
Vomiting: Frequent or intermittent vomiting, sometimes with bile or blood, can indicate inflammation in the stomach or upper intestines.
Diarrhoea: Loose, watery stools, often with mucus or blood, are common in cases of gastroenteritis or chronic intestinal inflammation.
Abdominal Pain: Dogs may exhibit signs of abdominal discomfort, such as whining, restlessness, or guarding their abdomen.
Loss of Appetite: Inflammation can cause nausea, leading to a decreased interest in food.
Weight Loss: Chronic inflammation can impair nutrient absorption, leading to weight loss and poor body condition.
Lethargy: Dogs with digestive inflammation may become less active and show signs of fatigue due to discomfort or nutrient deficiencies.
Treatments for Digestive Inflammation
Dietary Management
Diet plays a crucial role in managing digestive inflammation. Feeding a hypoallergenic, easily digestible diet can help reduce the burden on the digestive system and alleviate symptoms. Diets formulated for dogs with sensitive stomachs often include ingredients like rice, sweet potatoes, and plant-based proteins, which are less likely to trigger inflammation.
Medications
Antacids and Proton Pump Inhibitors
Antacids and proton pump inhibitors (PPIs) are commonly used to reduce stomach acid production, which can help manage gastritis and other forms of digestive inflammation. These medications work by neutralising or reducing the production of stomach acid, thereby protecting the stomach lining and reducing irritation. PPIs such as omeprazole, pantoprazole and esomeprazole are often prescribed for chronic cases.
Anti-Inflammatories
Anti-inflammatory medications, including corticosteroids and NSAIDs, may be prescribed to reduce inflammation in the digestive tract. However, these medications must be used with caution, as they can also irritate the stomach lining and exacerbate symptoms. In some cases, safer alternatives such as natural anti-inflammatories (e.g., curcumin) are preferred.
Antibiotics
In cases where bacterial infections are the cause of digestive inflammation, antibiotics may be necessary to eliminate the pathogens and reduce inflammation. Commonly prescribed antibiotics for digestive infections include metronidazole and tylosin. These medications help to control the infection and prevent further complications.
Prokinetics
Prokinetics are medications that enhance gastrointestinal motility, helping to move food and waste through the digestive tract more efficiently. These medications can be useful in cases of chronic gastritis or gastroenteritis, where slowed motility contributes to symptoms like bloating and discomfort.
Best Diets for Dogs with Digestive Inflammation
Dietary management is key to controlling digestive inflammation. The best diets for dogs with digestive issues are those that are hypoallergenic, easily digestible, and formulated to support gastrointestinal health.
Hypoallergenic Diets
Hypoallergenic diets for dogs are designed to minimise the risk of allergic reactions and subsequent inflammation. These diets often include novel proteins, such as lentils or peas, and easily digestible carbohydrates like rice or sweet potatoes. Avoiding common allergens like beef, chicken, and dairy can help reduce the incidence of food-related digestive inflammation.
Easily Digestible Diets
Easily digestible diets are formulated to reduce the workload on the digestive system, making it easier for dogs to absorb nutrients without irritation. These diets typically include ingredients like boiled rice, pumpkin, and plant-based proteins, which are gentle on the stomach and intestines.
High-Fibre Diets
High-fibre diets can help manage digestive inflammation by promoting healthy bowel movements and supporting the growth of beneficial gut bacteria. Fibre-rich ingredients like oats, brown rice, quinoa, legumes (peas, chickpeas, fava beans and lentils) and vegetables like pumpkin and carrots, help to bulk up stools and prevent diarrhoea, making them an excellent choice for dogs with chronic gastrointestinal issues.
Probiotic-Enriched Diets
Diets enriched with probiotics support the health of the digestive system by maintaining a balanced gut microbiome. Probiotics like Bacillus velezensis, Lactobacillus and Bifidobacterium help reduce inflammation, improve nutrient absorption, and support overall gastrointestinal health. Probiotic-enriched diets are particularly beneficial for dogs with chronic digestive conditions.
Foods to Avoid for Digestive Issues
Certain foods and ingredients can exacerbate digestive inflammation and should be avoided in dogs with sensitive stomachs or chronic gastrointestinal conditions.
Animal Proteins
Animal proteins, especially beef, chicken, and dairy, are common allergens that can trigger digestive inflammation in sensitive dogs. These proteins can cause an immune response that leads to inflammation in the stomach or intestines. Opting for plant-based proteins can help reduce the risk of food-related digestive issues.
Grains
Grains like wheat, corn, and soy are potential allergens and can contribute to digestive inflammation in some dogs. Dogs with sensitivities to grains may experience symptoms like diarrhoea, bloating, and abdominal pain. Choosing grain-free diets with alternative carbohydrates like sweet potatoes or quinoa can help manage inflammation.
Fatty Foods
High-fat foods can be difficult for dogs to digest and may exacerbate conditions like pancreatitis or gastritis. These foods can increase the production of stomach acid, leading to further irritation of the digestive tract. Instead, opt for low-fat diets that include healthy fats from sources like flaxseed, rapeseed oil or coconut oil.
Artificial Additives
Artificial colours, flavours, and preservatives found in some commercial dog foods can irritate the digestive tract and contribute to inflammation. These additives can disrupt the balance of the gut microbiome and lead to gastrointestinal discomfort. Natural, additive-free foods are a better choice for dogs with digestive issues.
Mechanism of Action: Probiotics are beneficial bacteria that help maintain a healthy balance in the gut microbiome. They work by colonising the digestive tract and competing with harmful bacteria, thereby reducing inflammation and improving digestive function. Probiotic supplements are particularly useful for dogs with chronic digestive issues or those recovering from antibiotic treatment.
Mechanism of Action: Prebiotics are non-digestible fibres that serve as food for beneficial gut bacteria. By promoting the growth of these bacteria, prebiotics help to maintain a healthy gut environment and reduce inflammation. Prebiotic supplements, often derived from sources like chicory root (inulin) FOS and MOS, yucca schidigera and baobab, can support overall digestive health.
Mechanism of Action: Postbiotics are the by-products of probiotic bacteria that exert beneficial effects on the host, including anti-inflammatory actions. They help to support gut health by reinforcing the gut barrier and modulating the immune system, which can reduce overall digestive inflammation.
Mechanism of Action: L-Glutamine is an amino acid that plays a crucial role in maintaining the integrity of the gut lining. It helps to repair and protect the mucosal cells of the digestive tract, reducing the risk of inflammation and improving nutrient absorption. Glutamine supplements are beneficial for dogs with chronic gastrointestinal conditions or those recovering from digestive inflammation.
Slippery Elm
Mechanism of Action: Slippery elm is a natural herb known for its soothing properties. It forms a protective layer over the mucous membranes of the digestive tract, reducing irritation and inflammation. Slippery elm supplements can help manage symptoms like diarrhoea, vomiting, and abdominal pain, making them an excellent choice for dogs with digestive issues.
Aloe Vera
Mechanism of Action: Aloe vera is well-known for its soothing and healing properties, which extend to the digestive system. It has natural anti-inflammatory and antimicrobial effects, which help to reduce irritation and support the healing of the digestive tract. Aloe vera supplements or juice can be used to alleviate symptoms of gastritis or gastroenteritis.
Digestive Enzymes
Mechanism of Action: Digestive enzymes assist in breaking down food into smaller, more easily absorbed components. Supplementing with digestive enzymes can help dogs with digestive inflammation by improving nutrient absorption and reducing the strain on the digestive tract. These supplements can be particularly beneficial for dogs with exocrine pancreatic insufficiency (EPI) or chronic pancreatitis.
Marshmallow Root
Mechanism of Action: Marshmallow root is a soothing herb that helps to protect and heal the mucous membranes of the digestive tract. It has natural anti-inflammatory properties that can help reduce symptoms like pain and cramping. Marshmallow root can be administered as a supplement or in a herbal tea to support digestive health.
Best Herbs and Adaptogens for Digestive Inflammation in Dogs
Mechanism of Action: Chamomile is a gentle herb that has natural anti-inflammatory and antispasmodic properties. It helps to soothe the digestive tract, reducing cramping, bloating, and irritation. Chamomile can be administered as a tea, included in a dog’s food or in supplement form to support digestive health.
Mechanism of Action: Ginger is a well-known digestive aid that has natural anti-inflammatory and anti-nausea properties. It helps to calm the stomach and reduce symptoms like vomiting and bloating. Ginger can be used in small amounts as a supplement or added to a dog’s diet to support digestive health.
Peppermint
Mechanism of Action: Peppermint is an herb that helps relax the muscles of the digestive tract, reducing spasms and discomfort. It also has antimicrobial properties that can help combat digestive infections. Peppermint can be administered as a tea or in supplement form to alleviate symptoms of digestive inflammation.
Liquorice Root
Mechanism of Action: Liquorice root has natural anti-inflammatory and soothing properties, making it effective for managing digestive inflammation. It helps to protect the mucous membranes of the digestive tract and reduce irritation. Liquorice root can be used in herbal blends or as a supplement to support digestive health.
Marshmallow Root
Mechanism of Action: Marshmallow root is a soothing herb that helps to protect and heal the mucous membranes of the digestive tract. It has natural anti-inflammatory properties that can help reduce symptoms like pain and cramping. Marshmallow root can be administered as a supplement or in a herbal tea to support digestive health.
Dandelion Root
Mechanism of Action: Dandelion root is a natural diuretic and digestive tonic that supports liver function and helps to detoxify the body. It has mild anti-inflammatory properties that can help manage digestive inflammation. Dandelion root can be added to a dog’s diet as a supplement or used in herbal blends.
Adaptogens (Ashwagandha and Reishi Mushroom)
Mechanism of Action: Adaptogens like ashwagandha and reishi mushroom help the body adapt to stress and support overall immune function. In the context of digestive health, adaptogens can help reduce stress-related digestive issues and support the body’s natural ability to heal from inflammation. Ashwagandha helps modulate the immune response, while reishi mushroom has anti-inflammatory and immunomodulatory effects, making them beneficial for managing chronic digestive inflammation.

About Glendon Lloyd Dip.Canine.Nutrition Dip.Dog.Nutrigenomics
I have had dogs from the day I was born. Much to my Mum's amusement, my Dad bought home Zetta, a beautiful corgi puppy on the day, as his contribution to our new family!
Fast forward to 2018 and Catherine, my wife, and one of our dogs Poppy, were both diagnosed and treated for cancer within months of each other
Diet and its impact on health, cancer particularly, led me down a rabbit hole of discovery.
I consumed information voraciously - on our diets, our dogs' diets and the impact these have not just on health but also the health of our increasingly fragile planet.
I was humbled by the time and expertise given so freely by doctors and vets, canine nutritionists and scientists, academics and agronomists. The more I learned the more I understood there had to be a better way to improve not just our health but also our dogs and the planet's.
The result of my trip down that rabbit hole is Bonza, a plant-based dog food that elevates our dogs' diet beyond simple nutrition to a diet that inspires a healthier everyday life for our dogs and the planet.
I am continually researching the nutritional impact our dogs' diets have on their health and wellbeing and the ingredients and nutrients we should include in, and exclude from, their food to deliver longer, healthier lives.
I am delighted that my trip down the rabbit hole has led to me completing a Diploma in Canine Nutrigenomics and a Diploma in Canine Nutrition being awarded a Distinction for both my coursework and theses!
