What Ancient Grains Puppy Dry Dog Food is made of, ingredients and materials
Ancient Grains Puppy is a dry kibble formulation packaged in paper/cardboard. Dry pet foods rely on preservatives and processing stabilizers, not coatings or glazes, so traditional ceramic and non-stick hazards (lead, Teflon-type coating fumes) do not apply. The primary material exposure is the bag itself, paper and cardboard can absorb moisture and odors but do not leach into kibble under normal storage. No enamel, glaze, or resin-based surface treatment is present on the kibble itself.
What’s concerning
Category baseline
The starting point for this type of product, before anything specific to this product is counted.
No PFAS disclosure
No public statement from the brand about PFAS in this product.
Mycotoxin (aflatoxin) contamination
Dry kibble is vulnerable to aflatoxin-producing molds if stored improperly or if source grains were contaminated. Open Farm has not disclosed testing protocols or limits for this known pet food hazard.
Lead
Grains and mineral premixes can accumulate heavy metals; without third-party testing disclosure, the actual levels in this product are unknown. Premium positioning does not guarantee screening.
Source, ATSDR ↗PFAS
PFAS has been detected in some premium dry pet foods, including in cardboard packaging with water-resistant coatings. Open Farm has not published testing or mitigation data for this product line.
Source, ATSDR ↗What’s reassuring
Cardboard/paper bag material integrity and secondary contamination
Paper bags do not leach chemicals into dry kibble under normal conditions. However, prolonged exposure to humidity or pests can compromise bag integrity and allow mold or foreign matter ingress.
Artificial preservatives or additives (e.g., BHA, BHT, ethoxyquin)
Product labeling markets 'natural' ingredients, suggesting avoidance of synthetic preservatives, but full ingredient and preservative declaration is not provided in this brief. Confirmation from packaging or company spec sheet is needed.
How is this PFAS grade calculated?
The brand's record and disclosure
Open Farm has not published comprehensive disclosure on PFAS, heavy metal testing, or mycotoxin screening for this product line, despite PFAS being detected in some premium pet foods. The brand markets 'ancient grains' and 'natural' positioning but does not reference third-party verification (AAFCO certification details, independent lab reports, or allergen/contaminant testing) on public channels. No major recalls or safety controversies are on record for this specific SKU as of available data.
How it compares in its category
Dry dog foods as a category carry lower chemical risk than wet foods (no BPA from cans) and avoid processing through plastic storage. However, many premium brands still withhold testing data on aflatoxins, lead, or PFAS in the final product. Open Farm's silence on these metrics places it in the middle tier of transparency; some competitors (e.g., brands with published third-party testing or NSF certification) disclose more, while economy brands often disclose nothing.
If you buy it
Store unopened bags in a cool, dry place away from direct sunlight to prevent cardboard degradation and moisture ingress, which can promote mold growth. Once opened, transfer kibble to an airtight rigid container (glass or food-grade plastic) to minimize exposure to ambient humidity and dust. Check expiration dates and do not use kibble that shows visible mold, off odors, or clumping. Request third-party testing data from Open Farm on heavy metals and PFAS before repurchasing in bulk.
