gpp_maybeBlue Buffalo 2015 “No By-Products” Lawsuit — What the Record Shows
Blue Buffalo built its brand partly on the “True Blue Promise” — most prominently: No Chicken or Turkey By-Product Meal. In 2014, Purina ran independent lab tests on Blue Buffalo products and found poultry by-product meal in multiple SKUs. Purina filed suit.
In May 2015, Blue Buffalo settled, paying $6 million to Purina and acknowledging that some of its products did contain poultry by-product meal. Blue Buffalo attributed the contamination to an ingredient supplier mislabeling, effectively arguing it was a supply chain verification failure rather than intentional deception.
Blue Buffalo has since claimed to have strengthened its incoming ingredient testing protocols. Current products continue to market the no-by-products claim. This incident is worth knowing when evaluating how much weight to give the brand's ingredient transparency claims.
LifeSource Bits — Meaningful Differentiator or Marketing?
Blue Buffalo's LifeSource Bits are small dark-colored pieces mixed into the kibble, distinct from the main kibble. Blue Buffalo claims these are cold-formed rather than extruded at high temperatures, which preserves heat-sensitive nutrients including vitamin C, vitamin E, zinc, selenium, and antioxidants more effectively than standard processing.
The underlying premise is nutritionally sound: high-temperature extrusion (120–150°C) does degrade some water-soluble vitamins, and lower-temperature processing would theoretically preserve more active compounds. The gap: there are no independent peer-reviewed studies demonstrating that LifeSource Bits produce measurable improvements in nutrient bioavailability or health outcomes in dogs compared to standard kibble.
Wellness does not have an equivalent system. Wellness' positioning is ingredient density — more animal protein, cleaner ingredient lists — without a process-based marketing claim.
Line-by-Line — Same Goal, Which to Choose?
| Goal | Wellness Line | Blue Buffalo Line | Recommendation |
|---|---|---|---|
| Maximum protein grain-free | CORE Original (~38–40% DM) | Wilderness Chicken (~34–36% DM) | Wellness CORE (protein density edge) |
| Grain-inclusive premium | Complete Health Adult (~28–30% DM) | LPF Chicken & Brown Rice (~26–28% DM) | Similar — Wellness protein slightly higher |
| Salmon / fish line | CORE Salmon & Herring | Wilderness Salmon | Similar — Wellness ingredient naming slightly more transparent |
| Small breed | CORE Small Breed | Wilderness Small Breed | Similar — choose by price and availability |
| Single-protein LID | Simple Limited Ingredient | Basics LID | Similar — verify ingredient list before choosing |
| Prescription / vet diet | None | Natural Veterinary Diet | Blue Buffalo (but less clinical evidence than Hill's/RC) |
favoriteDCM Risk — Both Grain-Free Lines Carry Equal Concern
Wellness CORE and Blue Buffalo Wilderness both use peas and lentils as primary carbohydrate sources and both fall within the FDA's DCM investigation scope. DCM risk is equivalent between the two brands at the grain-free line level. If DCM risk is a concern, choose the grain-inclusive lines from either brand: Wellness Complete Health or Blue Buffalo LPF — both use grains (not legumes) as the primary carbohydrate source.

자주 묻는 질문
Q. What actually happened in Blue Buffalo's 2015 lawsuit?
Purina sued Blue Buffalo after independent lab testing detected poultry by-product meal in Blue Buffalo products — contradicting the brand's core 'True Blue Promise: No Chicken/Turkey By-Product Meal' claim. Blue Buffalo settled in 2015, paying $6 million to Purina and acknowledging that some products did contain poultry by-product meal. Blue Buffalo attributed it to an ingredient supplier mislabeling, but the settlement confirmed a failure of supply-chain verification.
Q. Does LifeSource Bits actually improve nutrition absorption?
Blue Buffalo's claim is that LifeSource Bits are cold-formed rather than extruded at high temperatures, which better preserves heat-sensitive nutrients like vitamin C, vitamin E, zinc, and selenium. The concept is nutritionally plausible — high-temperature extrusion does degrade some water-soluble vitamins. However, there are no independent peer-reviewed studies demonstrating that this processing difference produces measurable health improvements in dogs. It is a reasonable differentiator as a concept, but the clinical evidence isn't there yet.
Q. Which has more protein — Wellness CORE or Blue Buffalo Wilderness?
Wellness CORE Original sits at approximately 38–40% protein on a dry-matter basis. Blue Buffalo Wilderness Chicken is approximately 34–36% DM protein — about 4 percentage points lower. Both are positioned as high-protein grain-free formulas, but CORE has a meaningfully higher protein density.
Q. If both are grain-free, is DCM risk the same for both brands?
Yes — for their respective grain-free lines, both brands use peas and lentils as primary carbohydrate sources and both fall within the FDA's DCM investigation scope. The risk is equivalent between Wellness CORE and Blue Buffalo Wilderness. If DCM is a concern, both brands offer grain-inclusive alternatives (Wellness Complete Health; Blue Buffalo LPF with brown rice) that avoid the legume-heavy carb structure.
Q. How does Blue Buffalo's Natural Veterinary Diet compare to Hill's or Royal Canin prescription diets?
Blue Buffalo Natural Veterinary Diet covers kidney, weight, digestive, and joint conditions. Compared to Hill's Prescription Diet and Royal Canin Veterinary Diet, it has significantly less accumulated independent peer-reviewed clinical data backing each specific formula. For disease management where prescription diet efficacy is critical, Hill's and Royal Canin are better-evidenced options. Blue Buffalo's vet diet line is a reasonable alternative when the others are unavailable, not a first-choice for serious therapeutic cases.
