🧠🐶 You Won’t See This Nutrient on Trend Lists — But It’s Vital to Your Dog’s Health: Thiamine (Vitamin B1)
Homemade diets can look incredibly nourishing — fresh meats, organs, and bones — but there’s one critical nutrient that is almost always deficient when diets are not carefully formulated or audited:
👉 Thiamine (Vitamin B1)
This is especially true for diets based solely on beef, chicken, or turkey, and for popular 80/10/10 prey model recipes.

🔬 Why Thiamine Is Essential
Thiamine is a water-soluble B vitamin that dogs cannot produce on their own. It must be supplied consistently through the diet.
It is required for:
⚡ Energy metabolism (carbohydrates → usable energy)
🧠 Brain and nervous system function
💪 Normal muscle function
🍽️ Healthy appetite and digestion
Without enough thiamine, the body literally cannot generate energy efficiently, especially for the brain.

⚠️ Signs of Thiamine Deficiency
Deficiency often begins subtly and is frequently overlooked:
➡️ Low energy or lethargy
➡️ Decreased appetite or weight loss
➡️ Vomiting or GI upset
➡️ Weakness or uncoordinated movement
➡️ Neurological signs (tremors, seizures)
👉 Good stool quality does not rule out a thiamine deficiency.

🥩 Why 80/10/10 & Prey Model Diets Often Fall Short
The 80/10/10 model focuses on ratios — not nutrient adequacy.
Common issues:
❌ Beef, chicken, and turkey are poor to moderate sources of thiamine
❌ Muscle meat + bone + organ ratios do not guarantee micronutrient sufficiency
❌ No margin of safety without formulation or nutrient analysis
❌ No fortification like commercial diets
A diet can be “species-appropriate” and still be nutrient-deficient.

🌿🐟 Thiamine-Rich Foods That Help Prevent Deficiency
To meet (and exceed) thiamine minimums, intentional inclusion of rich sources is essential.
Excellent sources include:
💛 Nutritional yeast (very rich and highly effective)
🐖 Pork (one of the best whole-food sources)
🐟 Salmon (moderate source with added omega-3 benefits)
👉 Including at least one of these at therapeutic levels is critical when feeding homemade diets — especially those dominated by beef, chicken, or turkey.
Even better, add two of these sources every day.

🧠 The Big Takeaway
Homemade diets require more than good intentions and ratios.
✅️ Balance is about nutrients, not ingredients
✅️ Thiamine deficiency is common — and preventable
✅️ Formulation or professional auditing protects long-term health
