Detailed Causes of Diarrhoea in Dogs
What are the Different Types and Causes of Diarrhoea in Dogs?
Diarrhoea in dogs can broadly be classified into two types based on the part of the intestines affected.
Small Intestinal Diarrhoea
This type involves the small intestine and often results in large-volume, less frequent stools, sometimes accompanied by weight loss. Causes include:
- Infections: Viral (parvovirus, coronavirus), bacterial (Salmonella, E. coli), or parasitic (giardiasis, hookworms) infections.
- Diseases: Conditions like inflammatory bowel disease (IBD), pancreatitis, or systemic diseases such as liver or kidney failure can contribute.
- Dietary Indiscretions and Allergies: Eating non-food items, sudden diet changes, or food allergies.
- Blockages: Caused by ingestion of foreign objects leading to partial or complete intestinal obstruction.
Large Intestinal Diarrhoea
Affecting the colon, this type results in small volume but frequent bowel movements, often with mucus or blood. Causes include:
- Colitis: Inflammation of the colon, often due to stress, infections (Clostridium perfringens, Campylobacter), or inflammatory disorders.
- Parasitic Infections: Whipworms are a common parasitic cause of large intestinal diarrhoea.
- Cancer: Though less common, tumours in the colon can lead to diarrhoea.
Symptoms of Diarrhoea in Dogs
Symptoms vary depending on the underlying cause and type of diarrhoea but may include:
- For Small Intestinal Diarrhoea: Increased stool volume, vomiting, weight loss.
- For Large Intestinal Diarrhoea: Urgency, straining, blood or mucus in the stool.
Treatment Options
Dietary Management
A crucial first step in treating diarrhoea involves dietary adjustments.
- Fasting: Initially, a 24-hour fasting period can help rest the dog’s gut. However, you shouldn’t do this if they are very young
- Fibre: Plays a crucial role in managing diarrhoea by absorbing excess water and promoting a healthy gut flora. Best fibre options include:
- Prebiotics: Foods like sweet potato, pumpkin, and oats nurture beneficial gut bacteria. Supplements containing inulin (derived from chicory root), baobab, fructooligosaccharides (FOS), mannan-oligosaccharides (MOS), and beta-glucans can also support gut health.
Probiotics
Veterinary-formulated probiotics can rebalance gut bacteria, aiding in recovery. There is a significant body of research that has demonstrated the benefits, and efficacy, of probiotics for dogs with diarrhoea.
Postbiotics
Postbiotics for Dog Diarrhoea
Postbiotics are the bioactive compounds produced by probiotics during fermentation. These include short-chain fatty acids, peptides, and other metabolites that play a crucial role in maintaining gut health and managing diarrhoea in dogs. For further information on the role postbiotics play in managing diarrhoea see this article Postbiotics for Dog Diarrhoea.
Natural Anti-Inflammatory Options
In addition to medical treatments, certain natural foods, herbs, and spices can help reduce gut inflammation:
- Foods: Blueberries and cranberries, seaweed (rich in omega-3 fatty acids), and broth can soothe the digestive tract.
- Herbs and Spices: Turmeric (curcumin), ginger, and peppermint have been shown to have anti-inflammatory properties that can benefit dogs with diarrhoea. However, dosages should be managed carefully and discussed with a veterinarian, as some natural remedies can interact with medications or be toxic in high amounts.
Hydration
Ensuring your dog remains well-hydrated is essential, especially in cases of severe diarrhoea where IV fluids might be necessary.
Medications
Prescribed medications may include antiparasitics, antibiotics, or anti-inflammatories, depending on the diagnosed cause. This should be a last resort as many medications can result in affecting an already distressed gut.
