Pure Vita Grain Free Salmon Formula Dry Dog Food

❌ Oxide is the worst grade of mineral form — barely absorbed, cheapest to buy. Look for magnesium proteinate; magnesium sulfate is the acceptable middle.

Cholecalciferol is vitamin D3 — the standard, AAFCO-required form of vitamin D in complete dog food, and its presence on a label is expected rather than alarming. Dogs cannot make meaningful vitamin D in their skin from sunlight the way people do, so it has to come from the diet. Two things are worth knowing. D3 is more potent than D2 (ergocalciferol) and has a narrower safety margin — it is the form used in rodenticides. And the real-world risk is manufacturing error, not the ingredient: FDA recalls in 2018–19 found dog foods containing up to 70x the intended vitamin D, causing hypercalcemia, kidney failure and deaths across brands including Hill's, Nutrisca, Sunshine Mills, Kroger and ELM. An ingredient label cannot tell you the amount, only that it is present — so this is flagged for awareness, not as a mark against the food.

Garlic's toxic reputation traces to Lee et al. (2000), which fed dogs 5 g/kg body weight daily for a week — roughly 20 cloves a day for a 20kg dog. That produced Heinz bodies and reduced hematocrit, but no dog developed clinical hemolytic anemia. Typical holistic dosing (about a quarter clove per 10 lb) is roughly 20x lower than that study. A 2025 in-vitro study (Beleć, Barć & Lasek, Animals) found no safe threshold has been established, so caution is still warranted — but garlic is not in the same category as onion, which carries stronger evidence of harm. In commercial food it is usually a trace flavoring listed below salt.

⚪ Formulation signal: yeast culture and hydrolysed yeast are used as cheap palatants — the same job as animal digest. Note the distinction: BREWER'S YEAST is a genuine whole-food source of B vitamins and is not flagged here. It is the processed flavouring forms that signal a food needing help to be eaten.
