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 is organic brown rice, a complex carbohydrate that (once cooked) can be fairly easy to digest. However, aside from its natural energy content, rice is of only modest nutritional value to a dog.
The fourth ingredient lists organic chicken liver. This is an organ meat sourced from a named animal and thus considered a beneficial component.
The fifth ingredient includes organic carrots. Carrots are rich in beta-carotene, minerals and dietary fiber.
The sixth ingredient is organic potato. Potatoes can be considered a gluten-free source of digestible carbohydrates. Yet with the exception of perhaps their caloric content, potatoes are of only modest nutritional value to a dog.
The seventh ingredient is organic apple, a nutrient-rich fruit that’s also high in fiber.
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 ingredient is organic flaxseed meal, one of the best plant sources of healthy omega-3 fatty acids. Flax seeds are also rich in soluble fiber.
However, flaxseed contains about 19% protein, a factor that must be considered when judging the actual meat content of this dog food.
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 most experts favor the ingredient for its numerous health benefits, garlic (in rare cases) has been linked to Heinz body anemia in dogs.2
However, the limited professional literature we surveyed provided no definitive warnings regarding the use of garlic — especially when used in small amounts (as it likely 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 this recipe contains a number of organic ingredients, we feel compelled to grant this line a more favorable status as we consider its final rating.
That’s because organic ingredients must comply with notably more stringent government standards — standards which significantly restrict the use of any synthetic pesticides, herbicides, insecticides, hormones or antibiotics.
With that in mind…
Judging by its ingredients alone, Castor and Pollux Organix canned dog food looks like an above average wet product.
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 30% for the overall product line.
And a fat-to-protein ratio of about 83%.
Below-average protein. Above-average fat. And above-average carbs when compared to a typical wet dog food.
When you consider the protein-boosting effect of the flaxseed meal, this looks like the profile of a wet product containing a moderate amount of meat.
Castor and Pollux Organix is a meat-based canned dog food using a moderate amount of chicken or turkey as its main sources 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.
