Wellness Core Original Dry Dog Food
Lower PFAS concern for the product itself; packaging is standard dry-food bag with no known PFAS risk profile.
Wellness CORE Original is a dry dog food in conventional kraft paper packaging with likely polyethylene or polypropylene lining, standard food-grade materials with no public evidence of PFAS treatment. The brand does not disclose PFAS practices.

The full breakdown
What it's made of and why it matters
Wellness CORE Original comes in a kraft paper bag with a polymer (plastic) interior lining, the industry standard for dry pet food. This layered construction keeps moisture and oxygen out, preserving kibble freshness and preventing rancidity of the fat content. The polymer lining is typically polyethylene or polypropylene, inert materials that do not leach into dry kibble under normal storage conditions. No evidence suggests the bag itself introduces contaminants into the food.
The brand's record and disclosure
Wellness (owned by WellPet LLC) maintains certification by AAFCO (Association of American Feed Control Officials) for complete and balanced nutrition. The brand has no major recalls specifically tied to packaging contamination or chemical safety concerns in recent years. Wellness publishes ingredient sourcing and manufacturing facility information but does not publicly disclose detailed testing protocols or third-party certifications for heavy metals or contaminants in the finished food itself. They are silent on PFAS in packaging, consistent with the broader pet food industry.
How it compares in its category
Dry dog food bags are functionally similar across brands; kraft-polymer construction is universal. Wellness CORE sits in the premium segment (higher protein, grain-free formulations) but uses the same packaging materials as mid-range and budget competitors. Some premium brands (e.g., Primal, Stella & Chewy's) offer freeze-dried or refrigerated alternatives that eliminate bag storage concerns entirely, though at higher cost. Standard kraft-lined bags carry no documented safety advantage over one another.
If you buy it
Store the bag in a cool, dry place away from direct sunlight and heat sources to slow oxidation of fats, which can cause rancidity independent of packaging safety. Once opened, transfer kibble to an airtight plastic or glass container if storing for more than a few weeks; the original bag is not designed for extended open storage. Replace the bag if you notice dampness, odor changes, or visible mold, which indicate storage failure. Do not microwave or heat the bag itself; exposure to high temperatures could degrade the lining, though this is not a standard use pattern.
Beyond PFAS: other things we checked
Established hazard classes for this product type, assessed from public information. These never change the PFAS grade; a Likely flag caps the Verdict at “Buy with care.”
Heavy metals (lead, cadmium, arsenic) in ingredients
Pet food ingredients (especially plant-based proteins and minerals) can accumulate heavy metals from soil and water. Wellness does not publish third-party heavy metal testing results for this product; no recall has been issued, but routine monitoring by FDA is limited.
Mycotoxins (aflatoxin, vomitoxin) from grain/ingredient contamination
Dry pet foods are vulnerable to mold toxins during storage or ingredient processing. Wellness meets AAFCO standards but does not publicly disclose aflatoxin testing protocols; no recent recalls for mycotoxin contamination in this line are on record.
Polymer lining degradation and microplastic shed
The kraft-polymer bag lining does not degrade under normal storage conditions and does not come into contact with moisture or heat that would cause flaking. No evidence of microplastic contamination in dry kibble from intact packaging exists in published literature.
Rancidity and oxidative degradation of fats
High-fat formulations (CORE is protein and fat-rich) can become rancid if exposed to light, heat, or oxygen after opening. This is a storage issue, not a manufacturing defect, but palatability and digestibility decline over time; it is not a toxicological hazard.
Inadequate ingredient transparency for allergen risk
Wellness lists primary ingredients but does not always specify the source or processing method of rendered proteins and fats, which can complicate diagnosis of food sensitivities in sensitive dogs. This is a labeling practice issue, not a direct safety hazard.
What we don’t know
This grade is a model-based estimate from public materials, coatings, and brand disclosure at 72% confidence. It is not a lab result.
No independent PFAS lab test is on record for this exact product. A lab test could move the score in either direction.
The brand has not made a specific, verifiable PFAS-free statement, so part of this score reflects that missing disclosure rather than a confirmed material.
Formulations and coatings change between production runs. Always check the current label before buying.
