About Watchdog LabsThis food has a good amount of protein but is high in carbs, which is lowering the fat content somewhat and making it less nutritionally balanced compared to other dog foods we evaluated. Carbohydrates are cheap so they keep the food’s cost low. They are nutritionally useful to dogs in the right amounts, however, high amounts of carbs can reduce the much-needed meat-based protein and fat content.
To evaluate dog foods, we first calculate out the moisture. This is called the “dry matter basis” and shows you only the solid ingredients in the food. These estimated “dry matter” numbers are different from the food label, but a better way to understand the real nutritional value of the food. We also calculate the carbs. Find out more

Controversial Ingredients
Castor & Pollux does not have any controversial ingredients in this product.
Country of Origin
Castor & Pollux makes this product in the United States.
Meat & Fat Quality
The quality of meat and fat in this product is great. Three animal-based ingredients, (organic chicken, organic chicken meal, and organic chicken liver) identify the species they come from which is very important. Noted above, this product has a lower than average fat content, which is surprising considering the six sources of fat. This leads us to wonder what the actual volumes are of the following ingredients: organic sunflower seed meal, organic coconut oil, organic chicken fat, organic flaxseed, salmon oil and organic sunflower oil. The volume question aside, it is a sign of quality that Castor & Pollux include only named meat and fat ingredients.
Artificial Preservatives
This product contains 0 of controversial preservatives. It’s good to know that not all artificial preservatives are bad. That’s because they serve an important purpose, which is to prevent food from spoiling. However, we consider 11 artificial preservatives controversial because of their potential link to cancer and other serious health conditions.
Artificial Colors
No Artificial Colors.
Artificial Flavors
No Artificial Flavors, either. This food is free of artificial ingredients.
Castor & Pollux has no recalls in their history. This is a great sign of a company with thoughtfully enforced safety standards.
We love dog food brands that are committed to transparent business practices. If you make quality dog food you should be willing to openly talk about how it’s sourced and produced. That’s why we reached out to pet food companies, asking questions about all their brands and products. Each company had three weeks to reply to our messages.
