Quick Verdict

Merrick and Wellness CORE are the two strongest traditional canned wet dog foods in our comparison — both grain-free, both free of by-products, both with clean safety records. The choice comes down to what matters more: Merrick's deboned chicken clarity and better price, or Wellness CORE's higher protein density from turkey-plus-liver and independent brand status. Both are excellent. Neither is a wrong choice.

Head-to-Head Comparison

Ingredient Quality

Winner: Tie (different strengths)

Merrick leads with deboned chicken — whole muscle meat that's been mechanically separated from the bone. It's the clearest, most specific protein claim you'll find in canned dog food. The supporting ingredients (sweet potatoes, peas, chicken broth) are identifiable and serve nutritional purposes.

Wellness CORE leads with turkey and chicken liver — a dual-protein approach that combines lean muscle meat with nutrient-dense organ meat. Chicken liver brings concentrated iron, vitamin A, and B-complex vitamins that muscle meat alone can't match. The result is a more nutritionally diverse protein profile.

Merrick wins on protein clarity and specificity. CORE wins on protein diversity and nutritional depth. Both exclude by-products, fillers, and artificial additives completely.

Protein Density

Winner: Wellness CORE

CORE's dual-protein formula delivers higher protein content per serving than Merrick's single-source approach. The turkey-plus-liver combination provides not just more protein by percentage, but a more complete amino acid and micronutrient profile. The smooth pate format concentrates nutrition without the higher moisture content of Merrick's chunkier texture.

For owners who specifically want maximum protein per ounce — for active dogs, working breeds, or as a high-protein kibble supplement — CORE delivers more usable protein.

Safety Record

Winner: Wellness CORE (slightly)

Both brands have clean wet food safety records over the past five-plus years. No FDA recalls, no contamination events, no voluntary withdrawals for either product.

The tiebreaker: Merrick's parent company Nestlé Purina experienced recalls on other product lines in 2022-2023. While Merrick's own products were unaffected and the Hereford, Texas facility operates independently, the corporate connection is a fair consideration. Wellness operates under WellPet LLC without the same corporate recall history nearby.

For practical purposes, both are safe. For brand-level risk assessment, Wellness CORE's independent corporate structure provides slightly cleaner optics.

Ingredient Transparency

Winner: Merrick (slightly)

Merrick's USA manufacturing in their Hereford, Texas facility and specific ingredient labeling (deboned chicken, not just "chicken") demonstrate strong transparency. The Made-in-USA claim covers both manufacturing and significant ingredient sourcing.

Wellness CORE names all protein sources and excludes vague ingredient terms, but provides less specificity about manufacturing locations and ingredient origins than Merrick. Both are significantly more transparent than vet-recommended brands like Hill's or Pro Plan.

Texture and Format

Winner: Depends on your dog

Merrick's chunkier pate with visible texture provides more mouthfeel variety — some dogs prefer the stimulation of varied textures. It also looks more like "real food" when served.

CORE's smooth pate is more uniform and blends more easily with kibble. It's better for mixing, stuffing into puzzle toys, or feeding to dogs who prefer consistent textures.

If your dog prefers chunks: Merrick. If your dog prefers smooth pate or you use wet food as a kibble mixer: CORE.

Value Per Serving

Winner: Merrick

At $3.79 per 12.7 oz can ($0.30/oz) vs. CORE's $4.39 per 12.5 oz can ($0.35/oz), Merrick costs about 17% less. For a 50-pound dog on a wet-food-primary diet, that's roughly $30-40/month in savings — $360-480 per year.

Both offer premium ingredient quality without by-products, and both are grain-free. The quality gap between them is small; the price gap is not. Merrick wins the value calculation clearly.

When to Choose Merrick

Merrick is the right choice when:

• Value matters alongside quality: 17% savings vs. CORE with comparable ingredient standards makes Merrick the better deal
• You prioritize named, specific proteins: Deboned chicken as the #1 ingredient is the most transparent protein claim in the category
• USA manufacturing is important: Hereford, Texas production with domestic sourcing
• Your dog prefers chunkier textures: Merrick's more textured pate appeals to dogs who want mouthfeel variety
• You're upgrading from Hill's or Pro Plan: Merrick delivers better ingredients at a comparable price point

When to Choose Wellness CORE

Wellness CORE is the right choice when:

• Maximum protein density is the goal: Turkey-plus-liver provides more protein and micronutrient diversity per ounce
• Corporate independence matters: No Nestlé/Purina parent company — WellPet operates independently
• You use wet food as a kibble mixer: The smooth pate format blends seamlessly with dry food
• Your dog has specific micronutrient needs: Chicken liver's concentrated iron, vitamin A, and B vitamins provide benefits muscle meat alone doesn't
• Brand-level safety record matters: Wellness has no corporate-adjacent recall history

Final Recommendation

For most premium buyers, Merrick Grain Free is the better value. Deboned chicken first, clean labeling, USA manufacturing, and a 17% price advantage over CORE. The ingredient quality is excellent, the safety record is clean, and the savings add up meaningfully over time. It's the premium wet food that earns its price without overcharging.

Choose Wellness CORE if protein density is your primary concern. The turkey-and-liver formula delivers genuinely more nutritional substance per ounce, and the independent brand structure avoids the Purina corporate connection. If you're willing to pay the $30-40/month premium for higher protein density and brand independence, CORE delivers real differences — not just marketing ones.

Both brands prove that premium wet dog food doesn't require by-products, fillers, or artificial ingredients. The question isn't which is good — both are excellent. The question is which trade-offs matter more to you.
