Pet food labels may look clean and wholesome, but behind the scenes, some brands use a tactic calledĀ ingredient splitting to disguise the dominance of cheap fillers like grains and sugars. At Sanctum Paws & Fangs, we believe every ingredient should earn its place — not hide behind clever formatting. This guide reveals how ingredient splitting works, why it matters, and how to spot it like a pro.

🧪 What Is Ingredient Splitting?

Ingredient splitting is the practice of dividing a single ingredient into multiple sub-ingredients to push it further down the label — making it appear less dominant than it really is.

Example: Instead of listing ā€œpeasā€ once, a brand might list:

  • Pea protein
  • Pea flour
  • Pea fiber

Together, these may outweigh the meat in the recipe — but by splitting them, the meat appears first on the label. It’s a legal but misleading way to manipulate ingredient order.

šŸš Commonly Split Ingredients


Ingredient

Split Variants

Peas

Pea protein, pea flour, pea fiber

Corn

Corn gluten meal, corn flour, corn syrup

Rice

Brown rice, white rice, rice bran, rice flour

Potatoes

Potato starch, potato protein, dried potatoes

Soy

Soy flour, soy protein isolate, soybean meal


These ingredients are often used to inflate protein content or bulk up the recipe — without adding meaningful nutrition.


šŸ›‘ Why It’s Problematic

  • Misleading Labels: Makes it seem like meat is the main ingredient when it’s not
  • Nutritional Imbalance: Excessive carbs and plant proteins can lead to inflammation, allergies, and digestive issues
  • Allergy Risks: Hidden allergens may trigger reactions in sensitive dogs
  • Trust Erosion: Undermines transparency and consumer confidence

🧭 How to Spot Ingredient Splitting

  • Scan the first 5 ingredients — they make up the bulk of the food
  • Look for multiple versions of the same item (e.g., pea flour + pea protein)
  • Be wary of vague terms like ā€œnatural flavorā€ or ā€œmeat mealā€
  • Don’t be fooled by ā€œmeat is the first ingredientā€ claims — check what follows

🐶 Why It Matters

Dogs deserve food that’s honest, nourishing, and biologically appropriate. Ingredient splitting can mask a formula that’s heavy in carbs and light on real meat — which may contribute to skin issues, shedding, hot spots, and chronic inflammation.

šŸ›”ļø What to Choose Instead

  • Single or limited ingredient foods
  • Named proteins (e.g., ā€œduck,ā€ not ā€œpoultry mealā€)
  • Whole food sources — no by-products or synthetic fillers
  • Transparent brands that disclose sourcing and formulation

🐾 Final Thoughts

Ingredient splitting is a clever trick — but you’re smarter than the label. At Sanctum Paws & Fangs, we curate products that extend your pet’s life, not just fill their bowl. Because every dog deserves to thrive, not just survive.
