Merrick vs Purina Pro Plan — which brand is better?

What reviewers say about each brand
Summarised from video reviews across each brand’s line — what they consistently praise, where they push back, and who each is for.?
Reviewers praise
- Pet food division emphasizes American manufacturing with in-house production facilities and visible quality control processes
- Credit card products report to all three major credit bureaus and provide free monthly FICO score tracking
- Double-your-line credit cards deliver the promised automatic limit increase after seven months of on-time payments
Reviewers push back
- Pet food division makes nutritional information difficult to obtain through customer service channels
- Credit card products carry steep annual fees and APRs approaching thirty-six percent with no rewards programs
- Credit card customer service generates complaints about account closure difficulties and collections practices
Merrick operates as two distinct entities—a pet food brand struggling with transparency and nutritional disclosure, and a subprime credit card issuer known for high fees and poor customer service.
Reviewers praise
- Meets WSAVA guidelines and backed by decades of veterinary nutritionist research
- Conducts AAFCO feeding trials rather than relying solely on formulation standards
- Offers specialized formulas for working dogs and specific health conditions across life stages
Reviewers push back
- Relies heavily on byproduct meals and meat meals that critics call unfit for human consumption
- Uses ingredient splitting with corn gluten meal, whole grain corn, wheat bran to hide filler dominance
- Wheat as primary binder has highest incidence of causing sensitivities and digestive upsets
Purina Pro Plan is a veterinarian-backed, WSAVA-compliant brand with extensive research behind it, but ingredient quality and formulation choices divide opinion sharply between conventional vets and ingredient-focused reviewers.

The verdict, both ways
Read it through both lenses: which brand to trust for the category you’re buying, and who’s the stronger maker overall. They can give different answers — and that’s the honest result.
If you already know what you’re buying, the category decides it — pick the brand that leads the shelf you’re shopping.
As makers: Merrick leads 0 of 5 · Purina Pro Plan 4.
Breadth vs focus — and the right answer depends on the shelf.
Go with Merrick if…
…you want range and the safe default. It ranks #10 overall and competes across 2 fields, so there's a fit for most needs.
Go with Purina Pro Plan if…
…you care about its focus. It plays fewer fields (2) but is hard to beat where it does compete.
We don’t crown a winner. Globally they may both be top-tier; locally, the category can flip the answer. Pick the brand that’s strong where you’re actually shopping — when a brand doesn’t compete in a category, we leave it blank rather than invent a rank.
