Can you trust the scores from online kibble-rating sites?
Can you trust: With caution. Most rate the printed ingredient list, which says nothing about real digestibility, quality control or the maker's expertise (WSAVA, 2021). A high score can reward polished marketing more than nutritional validation. Use it as one input, never on its own.
General documentary information. For an individual animal, a veterinarian's advice takes precedence over any online content.
What these scores actually measure
Rating sites mostly assess the printed composition and ingredient order, through automatic rules (WSAVA, 2021). Yet the label reveals neither digestibility, nor finished-product control, nor whether a board-certified nutritionist is involved. The finding that undercuts the scores: two foods with near-identical ingredient lists can differ widely in real digestibility, which no label-based score can capture (Tufts Petfoodology, 2023).
How to use them without going wrong
These tools can serve as a first read, provided their method and independence are checked (Tufts Petfoodology, 2023). They carry no weight as an official nutrient profile or a veterinary opinion. The reference checklist remains the WSAVA's manufacturer assessment (WSAVA, 2021). A score should always be cross-checked against nutritional adequacy and the seriousness of the company before it changes a decision.
| What a score measures | What it does not measure |
|---|---|
| Printed ingredient list | Real digestibility |
| Printed composition | Quality control |
| Marketing claims | Maker's expertise |
