The first ingredient in this dog food is organic chicken. Chicken is considered “the clean combination of flesh and skin… derived from the parts or whole carcasses of chicken”.1
Chicken is naturally rich in the ten essential amino acids required by a dog to sustain life.
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 item lists organic brown rice, a complex carbohydrate that (once cooked) can be fairly easy to digest.
The fourth item lists organic chicken liver. This is an organ meat sourced from a named animal and thus considered a beneficial component.
The next three items include a series of organic vegetables and fruit…
The eighth ingredient is organic 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.
The ninth item includes organic flaxseed meal, one of the best plant sources of healthy omega-3 fatty acids. Provided they’ve first been ground into a meal, flax seeds are also rich in soluble fiber.
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, 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.2
Most of the literature we surveyed offered no conclusive evidence against the use of garlic… especially in small amounts (as it is here).
And lastly, 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.
Castor and Pollux Organix Canned Dog Food
The Bottom Line
Since Castor and Pollux Organix dog food contains an abundance of quality organic ingredients, we feel compelled to grant the product favored status when determining its 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.
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 28%. Together, these figures suggest a carbohydrate content of 28% for the overall product line.
Below-average protein. Above-average fat. And average carbs as compared to a typical canned dog food.
Free of any plant-based protein boosters, this looks like the profile of a wet food containing a moderate amount of meat.
Yet because of the organic nature of its ingredients and the lack of any critical Red Flag items, this dog food is entitled to an upgrade to our next category.
Castor and Pollux Organix canned dog food is a meat-based wet product using a moderate amount of chicken or turkey 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.
