When we see different health issues in dogs, such as viral infections, bacterial infections, ear infections or even cancer, we often ask, “Is there something that we could have done to better support the immune system in our four-legged family members?” The answer to the question is yes!

This is a common question that arises as dogs age and immune function declines. First, we need to understand that 70% of the immune system is in the digestive tract. A dog with a compromised digestive tract will have suppressed immunity.  When a wolf kills an animal in the wild, he will ingest the gut contents of that animal. This is where the wolf will get his probiotics! The process of extruding to make kibble destroys probiotics which is also why Fido-Vite supplements come in a palatable powder. Probiotics are just one of the ingredients in Fido-Vite supplements shown through research to support immune function. Here is a list of other immunity supporting ingredients!

  • Coconut oil – Contains MCT’s shown to support the immune system with some viral and bacterial challenges.
  • Yeast Extract – Provides dietary nucleotides that are needed for rapidly turned-over immunity cells.
  • Mannan-oligosaccharides (MOS) & Fructo-oligosaccharides (FOS) – Are prebiotics that alter gut flora populations positively, enhancing immune capacity.
  • Zinc Amino Acid Complex – Highly available form is key to immune system macrophage performance.
  • Bovine Plasma – Supports intestinal probiotics and contains immune system boosting immunoglobin.
