Ingredient Wiki

FIRST 5 OF 23 COMPONENTS

Our read The ingredients

Lamb leads, with grains close behind

Signature feature

Real lamb

Real lamb is #1 the ingredient. Supports strong muscles, including a healthy heart

Purina says

What it is Lamb is an animal protein mixed into the kibble and listed first by weight. The recipe also uses chicken by-product meal, corn gluten meal and soybean meal.

Our grade

  1. Marketing
  2. Modest
  3. Meaningful

Lamb's first-place spot is real; the next 3 ingredients are grains. Your dog gets lamb in a recipe with a sizable grain base and several other protein sources.

Modest Real, but smaller than the pack makes it sound.

Carrots and peas sit below salt, pointing to small vegetable additions rather than a meaningful serving in the bowl.

  • 17 Dried Carrots
  • 18 Dried Peas

Our read The label

Average protein with a small joint extra

The number

33mg

At least this much glucosamine per cup. It is a small addition beside the doses commonly used in joint supplements.
  1. Is it a high-protein food?

    No

    Its protein sits just below the dry food average we track. Grains and concentrated plant proteins share the bowl with lamb and chicken.

  2. Where do the calories come from?

    Fat edges ahead

    Fat supplies about 38% of calories, just ahead of carbohydrates. Dogs needing a low fat diet should pass.

Feed it to
Healthy adults that do well on grains and a mix of lamb and chicken.
Skip it for
Puppies, dogs on a low fat diet, and dogs with lamb or chicken allergies.

    RECALL HISTORY // ONE

    1 FDA Recall On Record

    OCT 3, 2025
    SALMONELLA

    Pet Chews Bully Bites Treats Reflects the manufacturer, not this recipe.

    1 of these fell in the last three years. See the recall log

    One honest caveat. These figures are what a label will tell us: protein, starch, the top of the ingredient list, flagged additives and the brand’s recall record. They cannot tell you whether your dog will do well on this food. Allergies, gut sensitivity, age and health conditions all matter more than any of it, and none of them are printed on a bag. If your dog is thriving on a food whose figures read lower than this one, that is not a mistake, and we would not switch on our say-so.
