Ziwi Peak’s Provenance Air Dried Dog Food is considered a low risk food, with an average score of 8.5. The line features ingredients from 3 different regions in New Zealand. The food is extremely low in carbohydrates, at 1%, with average protein of 38% and average fat of 32%.

The ingredient quality score is affected by the addition of added vitamins and minerals, suggesting that the minerals are lacking from whole food sources. However, the minerals are chelated, which are better absorbed than non-chelated. 

Most, but not all, of the fish in these recipes is wild-caught, and most meats are described as free range and grass fed. Chicken is free range but duck and turkey are not.

Ziwi’s air dried food is moderately processed and the company describes it as gently air-dried and a “raw alternative.”. They claim the air dried foods are shelf-stable and as nutritious as raw food, but they don’t disclose the drying temperature or time. They do state the food is dried sufficiently to eliminate pathogens, which suggests there’s also sufficient heat to cause some nutrient loss. 

Ziwi Peak doesn’t disclose the omega-6:omega-3 ratio, which is unfortunate since AAFCO allows a very inflammatory limit of 30:1.
