Open Range Water Buffalo Limited Ingredient Diet Alkaline Grain-Free Dry Dog Food, 22-lb bag
Graded by The Sniff System
Canine Caviar Open Range Water Buffalo Limited Ingredient Diet Alkaline Grain-Free Dry Dog Food is a dry formula featuring water buffalo meal, designed without a specific life stage.
There aren't many strong positives to highlight for this formula. The guaranteed analysis shows a high protein content, but its source is a concern.
The biggest concern is the lack of an AAFCO statement, which means the nutritional completeness of this food is unverified. Also, chickpeas are the second ingredient, contributing to a formula dominated by plant proteins.
Hard to recommend for any dog due to the unverified nutritional completeness and plant-protein dominance.
Summary written by The Sniff System from the data above. Same rubric, same drivers, expressed in English.
Strong fit for medium-sized herding breeds like Australian Shepherds, Australian Cattle Dogs, and Border Collies navigating skin allergies. The protein deck is built around a single species (lamb), with algae oil at position 9 for EPA/DHA skin support, and the product is explicitly marketed as limited-ingredient. Aussies are working-line dogs that thrive on high-protein performance formulas. Coat quality also benefits from EPA+DHA. The National Research Council (2006) recommends a minimum of 2.6 grams of linoleic acid (an omega-6) per 1000 kcal of metabolizable energy to maintain skin barrier function in adult dogs (NRC, 2006) .

Auto-matched from this product's measurements (ingredients, life stage, calorie density) to a breed archetype. Not a substitute for vet input on your specific dog.
Sniff scored this formula 34/100, landing in D-tier territory. A hard cap of 59 also applied 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). Even without the cap, the base component scores sit below the next band. The structural fix would need to address protein quality as well.
No positive drivers crossed our reporting threshold.
