Gut Health for Dogs 2025: Support a Healthy Microbiome with Natural Food 🐶✨

By Dr. Duncan Houston BVSc

Your dog’s gut is more than just a digestive system—it’s the command center for immunity, mood, skin health, and even energy. Supporting the gut through natural food can dramatically improve your dog’s health and resilience.

I’m Dr. Duncan Houston, veterinarian and founder of Ask A Vet. Here's how I help pet owners use real food and smart supplements to build better digestion and long-term wellness in dogs.

🦠 What Is the Microbiome? 

• A complex network of bacteria, fungi, and microbes living in your dog’s gut
  
• Supports digestion, nutrient absorption, immunity, and inflammation control 
• Imbalances (dysbiosis) are linked to allergies, IBD, stress, and chronic illness

🔍 Signs of Poor Gut Health

• Chronic diarrhea, constipation, or inconsistent poop
  
• Gas, bloating, or vomiting
  
• Frequent skin infections or ear issues
  
• Anxiety, excessive licking, or poor appetite

✅ Best Natural Foods for Gut Health

1. Fermented Foods (introduce slowly) 

• Unsweetened kefir or goat milk (1 tsp–2 tbsp depending on size)
  
• Plain Greek yogurt (small spoonful daily)

2. Prebiotic-Rich Veggies

• Pumpkin, sweet potato, chicory root, zucchini, green banana
  
• Feed cooked or pureed for better absorption

3. Bone Broth

• Hydrating and rich in glycine, collagen, and amino acids that heal the gut lining
  
• Use unsalted, homemade or trusted commercial sources

4. Lean Proteins

• Turkey, chicken, white fish, kangaroo—cooked gently to reduce digestive load

💊 Gut-Healthy Supplements (Vet-Approved) 

• Probiotics: FortiFlora, Proviable, or spore-based strains (Bacillus subtilis)
  
• Digestive enzymes: Help with protein, fat, and carb breakdown 
• L-glutamine: Repairs intestinal lining and supports leaky gut recovery

📋 Sample Gut-Healing Meal

• 100g cooked turkey mince 
• ¼ cup mashed pumpkin + steamed zucchini 
• 1 tbsp bone broth 
• ½ tsp fish oil + gut support probiotic

🛑 What to Avoid

• Highly processed kibble with fillers and artificial preservative
  
• Excess starches (corn, soy, wheat) or fatty leftovers 
• Overuse of antibiotics or NSAIDs without gut support

🧠 Tips for Building a Better Gut Long-Term 

• Rotate proteins and ingredients (every 2–4 weeks)
  
• Use a journal to track poop, behavior, and reactions
  
• Don’t over-clean—dogs need exposure to good microbes!
