Wellness vs Merrick: Which Is Better in 2026?
Wellness (natural premium kibble) and Merrick (natural premium kibble with USA-sourced meats) represent different philosophies in dog nutrition. Choosing between them depends on your dog’s needs, your budget, and how much you value each brand’s particular strengths. This side-by-side analysis covers ingredients, pricing, recall history, and real-world performance to help you decide.
Quick verdict: Wellness is our top pick for most dog owners — its natural premium kibble offers CORE grain-free high-protein line; Complete Health whole grain line. Merrick is the better choice for owners specifically needing USA-sourced beef and deboned meats; high actual meat content (70% meat, 30% produce/vitamins), or if high-protein diets, usa-sourced meats, owners avoiding by-products is your primary concern.

Key Nutritional Differences
The most important ingredient differences between Wellness and Merrick come down to protein sourcing and processing method. Wellness uses Deboned chicken, salmon, or turkey as first ingredient, while Merrick relies on Deboned beef, chicken, salmon, or turkey as first ingredient; meat is first 3 in. Both meet AAFCO standards for complete and balanced nutrition, but their ingredient philosophies differ in meaningful ways that can matter for dogs with sensitivities, weight issues, or high-activity lifestyles.
When evaluating either brand, check the specific recipe’s ingredient list rather than relying on brand-level generalizations — individual recipe quality can vary significantly within a brand’s lineup.
Price & Value
Both Wellness and Merrick land in different pricing tiers, making budget a significant factor in the decision.
Wellness pricing:
- Estimated cost per pound: $2.20–$3.50/lb
- Estimated monthly cost (medium dog): $55–$80
- Availability: PetSmart, Petco, Chewy, Amazon, independent pet retailers
Merrick pricing:
- Estimated cost per pound: $2.50–$3.80/lb
- Estimated monthly cost (medium dog): $60–$90
- Availability: PetSmart, Petco, Chewy, Amazon, independent retailers
The price difference between these two brands reflects their different production methods, ingredient quality, and target markets. When comparing cost, factor in digestibility — higher digestibility means your dog absorbs more nutrients per calorie, which can offset some of the cost premium for higher-quality foods. A dog eating 20% less food because it absorbs nutrients more efficiently reduces the real cost gap.
Consider the total cost of ownership: premium food may reduce veterinary costs from diet-related conditions over time, though this is difficult to quantify for individual dogs.

Variety & Flavors
Wellness offers Both grain-free (CORE) and grain-inclusive (Complete Health) lines with primary focus on CORE grain-free high-protein line; Complete Health whole grain line. The brand’s recipe range covers Dogs needing natural ingredients, weight management, senior dogs.
Merrick’s product lineup emphasizes USA-sourced beef and deboned meats; high actual meat content (70% meat, 30% produce/vitamins) with options designed for High-protein diets, USA-sourced meats, owners avoiding by-products.
Dietary accommodation:
- Wellness: Both grain-free (CORE) and grain-inclusive (Complete Health) lines
- Merrick: Grain-free (Classic line) and grain-inclusive (Backcountry) options
For dogs with food allergies or sensitivities, recipe variety and the availability of limited-ingredient options matters more than the overall catalog size. Dogs that react to chicken or beef specifically need a brand with a reliable alternative protein source (salmon, lamb, venison, duck) in its lineup.
Dogs without dietary restrictions benefit from occasional recipe rotation — switching between protein sources every 3–6 months can reduce the risk of developing new food sensitivities and ensures dietary variety. Both Wellness and Merrick offer enough recipe variety for rotation feeding.
Recall History & Safety
Recall history is one of the most important safety signals when choosing a dog food brand. A brand with multiple recalls, especially for contamination issues, warrants scrutiny of its manufacturing controls.
Wellness: 2012 voluntary recall (elevated zinc levels in cat food — not dog food). No major dog food recalls in recent years
Merrick: No recalls under Purina ownership. Pre-acquisition, one 2010 voluntary recall for treats. Clean record since 2015
Both the FDA’s recall database and the Dog Food Advisor’s recall tracker are useful resources for staying current on any new recalls. Manufacturing recalls are often brand-wide or facility-wide events, so knowing which facility manufactures a brand’s food is useful context — some brands manufacture in their own facilities while others use co-manufacturers that produce multiple brands simultaneously.
When a brand has experienced a recall, the key follow-up question is: what manufacturing controls were changed as a result? Brands that have responded to recalls with transparent root cause analysis and documented process improvements are generally more trustworthy post-recall than brands with no explanation.

The Bottom Line
Neither Wellness nor Merrick is universally superior — the right choice is highly dog-specific. A healthy, active 3-year-old Labrador has different nutritional needs than a senior Beagle with kidney disease or a Frenchie puppy with food sensitivities. Start with your dog’s specific requirements, then evaluate which brand’s product lineup best addresses them at a price point you can sustain long-term.
Both brands have earned their positions in the market. Whichever you choose, consistency matters — switching foods frequently can cause digestive disruption. Once you find a formula your dog thrives on, stick with it unless your vet recommends a change.

Frequently Asked Questions
Q: Is Wellness or Merrick better for puppies?
A: Both brands offer puppy-specific formulas that meet AAFCO nutrient profiles for growth. For large-breed puppies, look specifically for formulas labeled “Large Breed Puppy” — these have controlled calcium-to-phosphorus ratios that support proper bone development. For small breeds, standard puppy formulas are fine. If your puppy has known sensitivities, choose whichever brand offers the protein source your puppy tolerates.
Q: Can I mix Wellness and Merrick together?
A: You can mix dog foods, but it’s rarely recommended outside of a gradual transition period. Mixed feeding can make it harder to identify which food caused a reaction if your dog develops digestive issues. If you’re switching between Wellness and Merrick, do a 7–10 day gradual transition: 25% new food / 75% old for days 1–3, 50/50 for days 4–6, 75% new for days 7–9, then full switch.
Q: Which brand do vets recommend more — Wellness or Merrick?
A: Veterinary recommendation rates vary significantly by brand category. Science-backed brands with extensive feeding trial data (Purina Pro Plan, Hill’s Science Diet, Royal Canin) receive the highest veterinary recommendation rates. Natural and premium brands generally receive fewer formal vet recommendations but may be suggested for specific conditions. Ask your specific veterinarian — their recommendation will be based on your dog’s health history and their clinical experience.
Q: How do I know if my dog is doing well on Wellness or Merrick?
A: After 4–6 weeks on a new food, healthy dogs typically show: firm, well-formed stools (not too hard, not loose); stable or appropriate weight; good energy levels and interest in meals; healthy coat with minimal excessive shedding or dandruff; no chronic digestive symptoms (gas, bloating, loose stools). If you see improvements in these markers after switching, the food is working for your dog. If markers worsen, consider the alternative.
Q: Are there any dogs who should avoid Wellness or Merrick?
A: Dogs with specific medical conditions (kidney disease, liver disease, urinary tract issues, severe food allergies) should eat prescription veterinary diets formulated for those conditions, regardless of the quality of over-the-counter foods like Wellness or Merrick.
