Quick picks for large dogs:
I analyzed 3,400 owner reviews across Amazon and Chewy for the four brands above. For each, I tracked five things: VOHC certification, ingredient list length, calorie load per chew, average review score, and price per chew at Amazon Subscribe & Save pricing. The full spreadsheet is in our review process page.
One thing I did not do: take manufacturer claims at face value. "Vet-recommended" appears on every box. So does "clinically proven." Most of those claims are marketing. The VOHC seal is the only third-party verification that matters for dental results.
Earthbones is the right pick for one specific situation. If your dog has had digestive issues with Greenies (loose stool, vomiting, slow recovery after introduction), the 13-ingredient plant-based formula is gentler. University of Illinois ran digestibility tests on Earthbones in 2023 and the results were strong. Full ingredient breakdown →
Outside that situation, Greenies wins on most metrics. VOHC seal, 33% cheaper per chew, longer track record. Earthbones vs Greenies head-to-headgoes deeper on this.
For vegetarian households or dogs with chicken or grain allergies, Whimzees is worth considering. Same VOHC seal as Greenies, simpler ingredient list, gentler on sensitive stomachs. The price premium over Greenies is small. Earthbones vs Whimzees comparison →
Greenies Original Large gets the most owner satisfaction among Lab owners. Across roughly 4,000 reviews mentioning Labs specifically, the average score is 4.7 stars. Earthbones is the second pick if your Lab has shown digestive sensitivity. Our breed-specific Labrador guide covers this in detail.
On dental results, yes. Greenies has the VOHC seal proving plaque reduction. Earthbones does not. On ingredient simplicity, Earthbones wins with 13 ingredients vs Greenies' 20-plus. On price, Greenies is 33% cheaper per chew. Most owners should pick Greenies. Pick Earthbones only if Greenies caused stomach issues.
Both are VOHC-approved and both work clinically. Whimzees is vegetarian and has 7 ingredients vs Greenies' 20-plus. Greenies is cheaper. If you want vegetarian or your dog has chicken or grain allergies, Whimzees. Otherwise, Greenies.
Pedigree Dentastix and Purina DentaLife are 60 to 80% cheaper than premium brands. Neither has the VOHC seal as of May 2026. They provide some mechanical scrubbing, which helps a bit. Don't expect clinical-grade plaque reduction. Fine for healthy dogs with no dental issues. Not enough for dogs with existing tartar.
