What Is the Microbiome?

Your dog’s microbiome is a complex network of bacteria, fungi, and viruses living both inside and outside their body. These microorganisms play a crucial role in various bodily functions, with the majority residing in the digestive system. This often-overlooked system is so vital to your dog’s health that it’s aptly referred to as the “forgotten organ.”

The Five Ways the Microbiome Supports Your Dog

Your dog’s microbiome is a powerhouse of support, influencing various aspects of their health and well-being. Here are five crucial ways in which the microbiome plays a pivotal role in supporting your dog:

1. Protection Against Pathogens

The microbiome acts as a front-line defense, shielding your dog from harmful invaders such as viruses, fungi, and pathogenic bacteria. The friendly bacteria within the microbiome secrete chemicals that can combat and neutralise these pathogens, preventing infections and diseases. By outnumbering and out-competing the harmful bacteria, the microbiome creates a protective environment for your dog’s overall health.

2. Forms a Protective Barrier

A key function of the microbiome is to form a protective barrier within your dog’s body. This barrier serves as a defense against drugs, toxins, allergens, and carcinogens. The microorganisms in the microbiome can attach to potential invaders, preventing them from penetrating deeper into the body. Additionally, this barrier helps eliminate toxins through the faeces, further safeguarding your dog from harmful substances.

3. Feeding Your Dog

Contrary to being parasites, the friendly bacteria in your dog’s gut microbiome actively contribute to their nutrition. These bacteria produce special proteins called enzymes, which aid in the digestion and utilisation of food. By transporting nutrients across the intestinal wall into the bloodstream, the microbiome ensures your dog receives the essential elements necessary for energy, cell maintenance, and growth.

The microbiome also plays a pivotal role in producing vital vitamins for your dog, such as thiamin and B vitamins. Notably, vitamin B12, essential for immune function, is exclusively synthesised by bacteria in the digestive tract. If the microbiome is compromised, it can impact your dog’s ability to obtain these crucial nutrients from their diet.

4. Affects Your Dog’s Mood

The intricate communication system between the microbiome and the brain, known as the gut-brain axis, plays a surprising role in your dog’s mood and behaviour. The microorganisms within the gut can influence the brain through nerves and hormones, creating a dynamic interaction. Research suggests that changes in gut bacteria composition correlate with stress in animals, highlighting the impact of the microbiome on your dog’s emotional well-being.

5. Critical Part of the Immune System

Perhaps the most significant role of the microbiome is its contribution to the immune system. The intestinal tract, lined with a mucous membrane containing the gut-associated lymphoid tissue (GALT), collaborates closely with the microbiome. Together, they form up to 90% of your dog’s immune system. Special immune cells, including lymphocytes, T cells, and B cells, work tirelessly to defend against pathogens, making the GALT the largest organ in your dog’s immune system.

Dysbiosis and Its Causes

Dysbiosis, the imbalance in microbial colonies, can lead to various health issues. Factors such as parasites, processed foods, genetically modified foods, and antibiotics can disrupt the delicate balance of the microbiome.

5 Signs and Symptoms of Dysbiosis in Dogs

1. Changes in Behaviour

Observe your dog’s behaviour for signs of stress, anxiety, or depression. Dysbiosis has been associated with alterations in gut-brain communication, affecting your dog’s overall mood and demeanour.

2. Irregular Bowel Movements

Pay attention to any changes in your dog’s bowel habits. Persistent diarrhea, constipation, or irregular bowel movements may indicate disruptions in the digestive system, often linked to dysbiosis.

5. Weight Fluctuations

Dysbiosis can impact your dog’s ability to absorb nutrients, leading to weight gain or loss. Unexplained fluctuations in weight may be a signal that the microbiome is not functioning optimally.

4. Dull Coat and Skin Issues

A healthy microbiome contributes to skin and coat health. If you notice a dull or unhealthy coat, along with skin problems like redness or flakiness, it could be a sign of dysbiosis affecting the skin’s protective barrier.

5. Persistent Infections

Recurring infections, whether in the ears, urinary tract, or elsewhere, may be indicative of a weakened immune system associated with dysbiosis. The microbiome’s role in supporting immune function is crucial for preventing infections.

The Impact of Dysbiosis — Leaky Gut Syndrome

Dysbiosis, the imbalance in the microbial communities within your dog’s microbiome, can have profound consequences, with one of the significant outcomes being the development of Leaky Gut Syndrome. Understanding this condition is crucial for dog owners who want to ensure their furry companions maintain optimal health.

Dysbiosis’s Role in Leaky Gut Syndrome

Mucous Membrane Disruption

The walls of your dog’s intestines are lined with a mucous membrane that plays a vital role in protecting the gut lining from abrasions caused by meals. Dysbiosis can disrupt this delicate mucous lining, leading to thinning and increased vulnerability.

Inflammation and Tight Junctions

As the mucous membrane becomes inflamed due to dysbiosis, the tight spaces between the cells of the intestinal lining open up. This compromises the integrity of the gut barrier, allowing harmful substances to pass through.

Damage to Intestinal Cells

Dysbiosis contributes to the deterioration and damage of intestinal cells. When these cells are no longer able to effectively screen out harmful substances, various toxins, bacteria, viruses, fungi, and undigested food particles can enter the bloodstream.

Recognising Signs of Leaky Gut in Your Dog

Chronic Inflammation

Once the microbiome is disrupted, chronic inflammation becomes a hallmark of Leaky Gut Syndrome. The immune system goes into overdrive as it attempts to process and eliminate the unwanted substances that have entered the bloodstream.

Food Allergies and Sensitivities

The compromised gut barrier allows undigested proteins and food particles to enter the bloodstream, triggering immune responses. This can manifest as food allergies and sensitivities, leading to symptoms such as itching, scratching, hot spots, and skin irritations.

Yeast Infections

Dysbiosis creates an environment where yeast in the microbiome can overgrow and thrive. Leaky Gut Syndrome allows these yeast organisms to enter the body, resulting in yeast infections that may manifest as infected ears and yeasty feet.

Gastrointestinal Issues

Inflammation and damage to the intestinal lining can cause a range of gastrointestinal problems, including inflammatory bowel disease, diarrhea, and constipation. The compromised gut function further contributes to nutrient malabsorption.

Autoimmune Issues and Joint Conditions

The continuous immune response triggered by Leaky Gut Syndrome can lead to autoimmune issues, such as allergies and even cancer. Additionally, the chronic inflammation may contribute to joint conditions and pain in affected dogs.

Other Systemic Effects

Leaky Gut Syndrome can have far-reaching consequences, affecting various organ systems. It has been linked to thyroid disease, liver dysfunction, pancreatic insufficiency, diabetes, mood disorders, weight gain, low energy, and slow metabolism.

How to Reverse Dysbiosis and Support Your Dog’s Microbiome

Reversing dysbiosis and fostering a healthy microbiome in your dog is achievable through strategic interventions, primarily centred around dietary changes and lifestyle adjustments. Here are five effective ways to restore balance and support your dog’s microbiome:

Avoiding Pesticides, Drugs, and Toxins

Natural Alternatives – Opt for natural alternatives to pesticides and drugs whenever possible. Chemicals can disrupt the delicate ecosystem in your dog’s gut, hindering the growth of beneficial microbes. Explore holistic approaches to pest control and consider herbal remedies.

Limited Toxin Exposure – Minimise your dog’s exposure to environmental toxins. Choose pet-safe cleaning products and be cautious with yard treatments. Reduced exposure to harmful substances helps preserve the integrity of the microbiome.

Feeding a Raw Diet for Microbiome Health

Diverse Microbial Communities – Studies suggest that a raw diet promotes a more diverse and robust microbiome in dogs. Raw, unprocessed foods provide essential nutrients and support the growth of beneficial bacteria, contributing to a healthier gut environment.

Reducing Inflammatory Foods – Unlike processed foods, a raw diet is often lower in inflammatory substances. By eliminating potential triggers for inflammation, you create an environment that discourages dysbiosis and encourages microbial balance.

Incorporating Probiotics for Microbial Balance

Supplementing with Probiotics – Probiotics, beneficial bacteria that support gut health, can be introduced through supplements or probiotic-rich foods. Look for high-quality probiotic products containing a variety of strains, such as Lactobacilli and Bifidobacteria, essential for a well-balanced microbiome.

Soil-Based Probiotics – Consider adding soil-based probiotics, like Bacillus subtilis and Bacillus coagulans, to your dog’s diet. These probiotics form a protective coating and are more likely to survive the digestive tract, enhancing their colonization in the gut.

Adding Prebiotics for Enhanced Gut Health

Non-Digestible Food Ingredients – Include prebiotics in your dog’s diet to enhance the effectiveness of probiotics. Prebiotics are non-digestible food ingredients that nourish beneficial bacteria in the gut. Supplements like inulin and fructooligosaccharides (FOS) can be added, or you can incorporate whole food sources such as dandelion greens and garlic.

Choosing High-Quality Supplements for Microbiome Support

Selecting the Right Probiotic Supplements – When selecting probiotic supplements for your dog, prioritise quality and efficacy. Look for products with a diverse range of bacterial strains, a high colony-forming units (CFUs) count, and consider soil-based probiotics for enhanced survivability in the digestive tract.

Proper Dosage – Follow the recommended dosage guidelines on the supplement container. Adjust the dosage based on your dog’s weight, ensuring they receive an adequate amount of beneficial bacteria to support the microbiome.
