The first ingredient in this dog food includes chicken. Chicken is considered “the clean combination of flesh and skin… derived from the parts or whole carcasses of chicken”.1
The second ingredient is water, which adds nothing but moisture to this food. Water is a routine finding in most canned dog foods.
The third ingredient is turkey, “the clean combination of flesh and skin… derived from the parts or whole carcasses of turkey”.2
Chicken and turkey are naturally rich in the ten essential amino acids required by a dog to sustain life.
The fourth ingredient includes chicken liver. This is an organ meat sourced from a named animal. So long as it’s not over-weighted in a dog food, chicken liver is a beneficial component.
The fifth ingredient lists pea flour, a powder made from roasted yellow peas. Pea flour makes a slightly healthier substitute for wheat and can support more stable blood sugar levels.
The next three nutrient-rich plant ingredients include…
The ninth ingredient is guar gum, a gelling or thickening agent found in many wet pet foods. Refined from dehusked guar beans, guar gum can add a notable amount of dietary fiber to any product.
From here, the list goes on to include a number of other items.
But to be realistic, ingredients located this far down the list (other than nutritional supplements) are not likely to affect the overall rating of this product.
With two notable exceptions…
First, this food also contains chelated minerals, minerals that have been chemically attached to protein. This makes them easier to absorb. Chelated minerals are usually found in better dog foods.
And lastly, garlic can be a controversial item. Although the majority of experts favor the ingredient for its numerous health benefits, garlic (in rare cases) has been linked to Heinz body anemia in dogs.3
However, the limited professional literature we surveyed provided no definitive warnings regarding the use of garlic, especially in small amounts (as it is here).

The Bottom Line
Judging by its ingredients alone, Castor and Pollux Organix Grain Free looks to be an above-average canned dog food.
But ingredient quality by itself cannot tell the whole story. We still need to estimate the product’s meat content before determining a final rating.
As a group, the brand features an average protein content of 34% and a mean fat level of 27%. Together, these figures suggest a carbohydrate content of 31% for the overall product line.
Below-average protein. Above-average fat. And near-average carbs when compared to a typical canned dog food.
Free of any plant-based protein boosters, this looks like the profile of a wet product containing a moderate amount of meat.
Since this Castor and Pollux Organix product line contains a notable number of quality organic ingredients, we feel compelled to accord this line favored status as we consider its final rating.
That’s because organic ingredients are produced under controlled government standards — standards which greatly restrict the use of any synthetic pesticides, herbicides, insecticides, hormones or antibiotics.
Castor and Pollux Organix Grain-Free is a grain-free canned dog food using a moderate amount of named poultry as its main source of animal protein, thus earning the brand 4 stars.
Rice ingredients can sometimes contain arsenic. Until the US FDA establishes safe upper levels for arsenic content, pet owners may wish to limit the total amount of rice fed in a dog's daily diet.
