Gut Bacteria: The Secret to Your Dog’s Health

Gut Bacteria - The Secret to Your Dog's Health

Although unseen, gut bacteria may greatly affect your dog’s health from supporting digestion to shaping their immune system to affecting your pup’s risk for diseases. You can’t see them, but they’re there. Bacteria are all around and within your dog’s body (and yours as well).

Don't panic! The vast majority of bacteria are either harmless or helpful for humans and their pets. In fact, scientists are just beginning to discover that bacteria actually play vital roles in shaping many aspects of health.

Read on to learn more about the role of bacteria in your dog’s health.

What is the microbiome?

All animals have unique collections of microbes (bacteria, fungi, viruses and other tiny things) in their digestive tracts, collectively termed the gut microbiome. Bacteria in the microbiome are crucial for digestion and obtaining nutrients from the food your dog eats. When these gut bacteria are out of balance, your dog could experience digestive disorders like inflammatory bowel disease (IBD).

Beyond digestion, gut bacteria influence many aspects of your dog’s overall health. In humans and animals, they have been shown to play important roles in developing allergies, diabetes, and even depression and anxiety.

Why should I care about my dog's gut microbiome?

    1. The microbiome is important for digestion

    Digestion is a multi-step process that starts in the mouth, passes to the stomach, and finishes in the intestines. Most of the bacteria in the gut microbiome are in the large intestine, where they help digest food your dog can’t break down alone. These bacteria are also responsible for production of vitamins (like vitamin B and K) and other essential nutrients.

    Like human communities, different types of bacteria in microbial communities have different skills and jobs. For instance, the Bacteroides are associated with fat and protein digestion from meat, while Prevotella are linked to carbohydrate digestion. There are countless different types of bacteria with roles that scientists are only just starting to uncover. When you put all these bacteria together into a balanced microbiome, their combined skills allow dogs (and humans) to digest a broad range of foods.

      2. The microbiome shapes your dog's immune system

      Your dog’s immune system is responsible for protecting your dog from infections. It is a complex network of cells, tissues and organs. When animals, including dogs, are raised in gnotobiotic environments (sterile - without gut bacteria), many parts of the immune system do not develop normally. For instance, gnotobiotic animals have fewer white blood cells, which are immune cells that circulate in the bloodstream and protect your dog from infections.

      There is a 0% chance that your dog has a sterile gut. However, different types of gut bacteria affect the immune system in different ways. Many types of bacteria trigger the immune system, since the immune system evolved to fight foreign bacteria. On the other hand, some bacteria such as Bacteroides actually suppress the immune system with anti-inflammatory properties.

      3. The microbiome affects your dog's risk for diseases

      Because the microbiome is linked to the immune system, gut bacteria affect your dog’s chance of developing a disease. When the immune system is under-reactive, your dog is at higher risk for catching infectious diseases. However, when the immune system is over-reactive, your dog’s body could trigger inflammation at inappropriate times. Long-term inflammation, left unchecked, can lead to chronic disorders such as inflammatory bowel disease, asthma, or even cancer.

      Gut bacteria have even been linked to mental health in humans and animals. More than half of the serotonin in animals’ bodies are a result of their microbiomes. Certain bacteria, including Lactobacillus rhamnosus (which is found in some yogurts), have an anti-anxiety effect similar to prescription drugs in mice.

      4. Your dog's microbiome is unique

      Many of the bacteria in your dog’s microbiome were inherited from its mother after birth. Other bacteria came from the environments and other animals (including you) that he or she was exposed to as a puppy. These bacteria will influence your dog for the rest of its life.

      Although the foundational members of gut communities are established early in life, the overall community changes with age, diet and lifestyle. If your dog is prescribed antibiotics, your dog’s microbiome could shift rapidly. Your dog’s unique microbiome and the choices you make that shape it have a profound impact on their overall health.

      Benefits to testing your dogs gut health

      What are the benefits of testing my dog’s gut health?

      • Establish a baseline profile of gut health: Your dog’s gut bacteria can be disrupted by things like antibiotics, infections and disease in the future. Every dog has a unique microbiome, and if you have a record of what this community looks like while your dog is healthy, you can help your dog return to a balanced community in the future.

      • Identify and treat imbalances before they become a problem: Even if your dog appears healthy, he or she could still have a bacterial imbalance that you do not know about. Early detection of imbalances in your pet’s microbiome could help you make dietary and lifestyle changes that might protect your dog from developing a disease.

      • Discover if your dog’s digestive disorder is linked to a bacterial imbalance: If your dog has a digestive disorder, you can compare their microbiome to those of healthy dogs and dogs with similar conditions. This information will be useful as you decide which interventions (diet, antibiotics, steroids, fecal transplants (FMT), etc.) will help you provide the best care for your dog, so they can have a happy and long life.

        We offer affordable solutions

        It’s estimated that 10% of pets in the US suffer from digestive issues, and diagnosis of a disorder like inflammatory bowel disease in your furry friend can cost thousands of dollars. That’s why we developed our microbiome assessment kits for dogs, which can help you and your veterinarian determine if your pet’s digestive issues may be linked to an imbalanced gut microbiome.

        In addition to offering microbiome assessments for pets, AnimalBiome has created Canine Gut Microbiome Restoration Supplements, FMT capsules that are given orally to treat symptoms like vomiting and chronic diarrhea in dogs.
