Peak Lamb with Green Vegetables Recipe Steam & Dried Dog Food, 28.8-oz bag
Graded by The Sniff System
ZIWI Peak Lamb with Green Vegetables Recipe Steam & Dried Dog Food is a dry food featuring lamb and lamb liver as its main protein sources.
This food has a strong protein profile, with lamb as the primary ingredient, which means high biological value for your dog. It also includes quality fat sources, like named fat with marine oil, providing beneficial EPA and DHA. Plus, the inclusion of various lamb organs adds diverse, highly bioavailable protein.
The main thing to watch out for is the lack of an AAFCO statement, which means the nutritional completeness of this food is unverified. This absence capped its overall score.
Good fit for dogs whose owners prioritize a strong protein profile and quality fats. Less ideal if you prefer food with verified nutritional completeness.
Summary written by The Sniff System from the data above. Same rubric, same drivers, expressed in English.
In its 2022 update on diet-associated DCM, the FDA identified Golden Retrievers as the most reported breed, with 121 cases out of 1,382 total canine reports (8.8%) received between January 1, 2014, and November 1, 2022 (FDA, 2022) . Good fit for active large sporting breeds like Golden Retrievers, Labrador Retrievers, and Irish Setters navigating diet-associated DCM concerns. Lamb anchors position 1, with 2 pulse-family ingredients in the top 15 (dried green peas at position 9, dried green lentils at position 10), plus lamb tripe at position 3 (a natural taurine precursor).

At 59/100, this formula lands mid-pack. The lift comes from protein quality, worth 23 points to the final number: Strong protein profile with lamb as the primary ingredient, delivering high biological value. The ceiling on this score is 59, set because the AAFCO nutritional adequacy statement isn't disclosed on the retailer page (so our methodology can't verify the formula meets adult, growth, or all-life-stages standards). The fix path: the brand publishing the AAFCO statement. That would lift the cap and put this formula above the B-band line at 60.
Strong protein profile with lamb as the primary ingredient, delivering high biological value.
Quality fat sources: named fat with marine oil (EPA and DHA source).
Includes egg, named fish, or organ meat for diverse high-bioavailability protein.
No AAFCO statement. Nutritional completeness unverified.

- 1protein animallamb
Real meat. Often used for dogs with chicken or beef sensitivities. Slightly higher fat content than chicken.
Position 1: primary protein source. After cooking removes water, this may drop in proportional weight, but it anchors the recipe.
- 2lamb lung
Position 2: co-primary protein. Two named animal proteins in the top 2 is a strong protein build.
- 3lamb tripe
Position 3. Named organ meat this high is a strong build choice. Concentrated source of taurine, glutamine, and B-vitamins.
- 4protein animallamb liver
Organ meat. Same nutrient-density story as chicken or beef liver, dense in B vitamins, iron, vitamin A.
Position 4. Named organ meat this high is a strong build choice. Concentrated source of taurine, glutamine, and B-vitamins.
- 5lamb heart
Position 5. Named organ meat this high is a strong build choice. Concentrated source of taurine, glutamine, and B-vitamins.
- 6lamb plasma
Position 6: supporting protein. Modest contribution to total protein weight.
- 7lamb bone
Position 7: supporting protein. Modest contribution to total protein weight.
- 8lamb spleen
Position 8. Functional organ inclusion. Adds amino acids and micronutrients even at smaller weight.
- 9dried green peas
Same as peas. Useful in small amounts. The concern is when pulses dominate the top of the ingredient list. See why →
Position 9. Moderate inclusion. Contributes carbohydrate and some plant protein.
- 10dried green lentils
Position 10. Moderate inclusion. Contributes carbohydrate and some plant protein.
- 11lamb fat
Position 11: trace protein. Likely there for amino-acid diversity or label appeal more than nutritional weight.
- 12lecithin
Natural emulsifier, usually from soy or sunflower. Helps blend fats and water. Safe at typical inclusion.
- 13lamb cartilage
Position 13: trace protein. Likely there for amino-acid diversity or label appeal more than nutritional weight.
