Individual Review: Diamond Naturals Grain-Free Beef & Sweet Potato Formula

This Diamond Naturals Grain-Free uses beef as its primary ingredient. It contains about 80% of water, which reduces after the cooking process. With that, the second ingredient, which is the lamb meal, compensates for the loss. The lamb meal is considered a meat concentrate and contains nearly 300% more protein than fresh lamb.

It also includes sweet potatoes, which are a gluten-free source of complex carbohydrates that are rich in dietary and beta-carotene. This will help improve the digestion process of your dog.

Aside from that, this formula provides highly digestible energy and limits the exposure of your dog to an allergy that might trigger their allergies and other sensitivities.

  • Crude Protein (Min) – 24%
  • Crude Fat (Min) – 14%
  • Crude Fiber (Max) – 5%
