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
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 organic chicken liver. This is an organ meat sourced from a named animal and thus considered a beneficial component.
The fourth ingredient is organic pea flour, a powder made from roasted yellow peas. Pea flour contains as much as 25% protein, a factor that must be considered when judging the meat content of this dog food.
The fifth item 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 flaxseed, 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.
However, flaxseed contains about 19% protein, a factor that must be considered when judging the actual meat content of this dog food.
The eighth ingredient includes organic apples, a nutrient-rich fruit that’s also high in 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 many favor the ingredient for its claimed health benefits, garlic has been linked to Heinz body anemia in dogs.2
So, one must weigh the potential benefits of feeding garlic against its proven tendency to cause subclinical damage to the red blood cells of the animal.
And lastly, this food 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
Grain Free 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 Grain Free 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.
The dashboard displays a dry matter protein reading of 34%, a fat level of 27% and estimated carbohydrates of about 31%.
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 canned dog food.
When you consider the protein-boosting effect of the pea flour and flaxseed, this looks like the profile of a wet product containing just a moderate amount of meat.
However, with 51% of the total calories in our example coming from fat versus just 26% from protein, some recipes may not be suitable for every animal.
Castor and Pollux Organix Grain Free 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.
Please note certain recipes are sometimes given a higher or lower rating based upon our estimate of their total meat content and (when appropriate) their fat-to-protein ratios.
