ORIJEN Tundra Grain-Free Poultry Free High-Protein Dry Dog Food is a dry food featuring lamb, venison, and duck as its primary proteins.

The formula also includes a variety of named fish and meals, adding diverse, highly bioavailable protein sources. Plus, the food has AAFCO feeding trial substantiation, which is a good sign of nutritional adequacy.

Nothing concerning in the deck.

Good fit for dogs needing a high-protein diet with diverse animal ingredients. Nothing serious working against it.

Summary written by The Sniff System from the data above. Same rubric, same drivers, expressed in English.

Who this is for

Frenchies have notoriously sensitive GI tracts plus a tendency toward obesity given their low activity needs. Limited-ingredient formulas with moderate calorie density tend to fit them well. Good fit for adult French Bulldogs and similar lower-energy companion breeds navigating a sensitive stomach. Lamb leads at position 1, but 7 stacked proteins make isolating triggers harder. What to watch: calorie density (463 kcal/cup) is rich for a lower-activity breed.

Methodology

The Sniff System grades this product against 3 cited studies relevant to its profile. Each link opens the original source.

Every claim on Sniff traces to a source. If you find a citation that's wrong, outdated, or misapplied, tell us.

Why this score

At 70/100, this formula lands in solid B territory. The lift comes from protein quality, worth 22.5 points to the final number: Strong protein profile with lamb as the primary ingredient, delivering high biological value. Secondary contribution comes from AAFCO compliance (+8 points). AAFCO feeding trial substantiation for not stated. The 5-point gap to the A-tier line is concentrated in fat-quality declaration (8 of 16 possible). Full fat-quality declaration requires a named-species animal fat (e.g., chicken fat, salmon oil) plus a marine oil with declared EPA/DHA milligram content.

  2. 2
    venison

    Real meat, lean and gamey. Used as a novel protein for dogs with sensitivities.

    Position 2: co-primary protein. Two named animal proteins in the top 2 is a strong protein build.

  3. 3
    duck

    Real meat. Often used as a novel protein for dogs with sensitivities to chicken or beef.

    Position 3: significant protein contributor. Adds amino-acid diversity to the top of the deck.

  13. 13
    pork

    Real meat. Dense protein and fat, though less common in dog food than chicken or beef.

    Position 13: trace protein. Likely there for amino-acid diversity or label appeal more than nutritional weight.

    Real animal fat from a named species. Clean energy source.

    Position 14: trace protein. Likely there for amino-acid diversity or label appeal more than nutritional weight.

    chickpeas

    Also called garbanzo beans. Affordable plant protein source, part of the legume stack the FDA examined in its heart-disease investigation. See why →

  24. 24
    peas

    Cheap protein bulk. Fine in small amounts, but when peas stack with lentils and chickpeas in the top ingredients, it's the pattern the FDA flagged in its heart-disease investigation. See why →
