Arm & Hammer vs Purina — which brand is better?
We compare them two ways: as makers overall — where each ranks and how trustworthy each is across everything it builds — and head-to-head inside each category they both sell in. We don’t crown a winner — the differences are the point.

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
- Baking soda presence delivers a distinctly clean sensation that fans appreciate across toothpaste and other formulations
- Nearly dust-free performance incat litter demonstrates strong engineering in particle control
- Toothpaste provides genuine cavity protection and realistic breath-fighting claims without overpromising
Reviewers push back
- Chemical smell signature to the brand irritates noses in both human and pet products
- Products sometimes fail to meet their headline claims, like cat litter not forming the advertised hard balls
- Sodium lauryl sulfate inclusion causes cheek sloughing and sensitivity issues in some toothpaste users
Arm & Hammer leans heavily on its signature baking soda formula across product lines, earning loyalty for that clean feeling but dividing users over its chemical scent, grittiness, and whether products deliver on their specific promises.
Reviewers praise
- WSAVA-approved formulations backed by veterinary nutritionists across all major product lines
- Exceptionally wide retail availability and accessible pricing compared to boutique brands
- Diverse specialized offerings within Pro Plan line for working dogs, sensitive stomachs, and life-stage needs
Reviewers push back
- Heavy reliance on byproduct meals, meat meals, and ingredient splitting with corn and wheat fractions
- High carbohydrate content problematic for weight management
- Artificial caramel coloring appears in some dry food formulas
Purina is a vast, Nestlé-owned manufacturer offering wide accessibility and WSAVA-approved formulations, but reviewers split sharply on ingredient quality—some praise meat-first recipes and specialized options, others condemn byproduct meals and filler splitting.
Where reviewers split on Arm & Hammer: The baking soda texture is polarizing—one reviewer loves the coarse particles and clean feel, while another finds the grittiness off-puttingAbrasiveness varies widely across the toothpaste line, with some formulas rated gentle and others harsh enough to cause sensitivity On Purina: Veterinarians and one reviewer insist Purina One and Pro Plan are largely equivalent in nutritional completeness, while a pet nutritionist flags Pro Plan's byproduct meals and filler splitting as disqualifyingSome reviewers see Pro Plan as genuinely premium with superior ingredient density and meaty chunks, others view the price premium as unjustified given similar vitamin profiles to Purina One
