Score
The Puglib score combines protein (quality on amino acids, and usable protein per calorie against a dog's need) with fat (the AAFCO minimums, plus credit for omega-3s). The protein requirement depends on life stage, so the score can differ by stage:
| Life stage | Puglib score | Rating | Protein | Fat |
|---|---|---|---|---|
| Puppy | 5.2 / 10 | Good | 4.6 / 10 | 7 / 10 |
- Calcium : phosphorus is 1.33 : 1, inside the AAFCO recommended 1:1 to 2:1.
