Overview
Diamond Naturals' large breed puppy formula, a lamb and rice recipe sold in a 40 pound bag and formulated for growth and development in large breed puppies.
It's built specifically for large breed puppies rather than puppies generally, with probiotics included for digestive and immune support alongside ingredients aimed at brain, eye, skin and coat development. The listing marks it pea-free and additive-free, though the flavor name references rice, worth checking directly if you're avoiding grains entirely.

Pros and cons
- Formulated specifically for large breed puppy growth

- Not suitable for adult dogs or non-large breeds

Performance notes
Probiotics are included specifically for digestive health and immune support during the puppy growth stage, while the large breed sizing targets the slower, controlled growth rate that big-breed puppies need compared with a general puppy formula.
