About Watchdog Labs
Nutrition

Nutrition

This 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

Top 5 Ingredients

Dog food ingredients are listed in descending order of weight. So when looking at a dog food label, take a close look at the first 5 ingredients. They make up about 80% of the total weight.


  • Organic Chicken
    Organic chicken is generally a healthy dog food ingredient. It provides nutrients like protein, fat, B vitamins, selenium and choline. Organic dog food ingredients are free of antibiotics, synthetic hormones, pesticides, chemical fertilizers and artificial preservatives. They are also not allowed to be genetically modified.
  • Organic Chicken Meal
    Organic chicken meal is generally a healthy dog food ingredient. Meat meals are the result of cooking. Water is removed from meats to create a protein-rich meal powder. Meat meals contain about four times the protein meats do, so generally, they're a good source of nutrients. Organic dog food ingredients are free of antibiotics, synthetic hormones, pesticides, chemical fertilizers and artificial preservatives. They are also not allowed to be genetically modified.
  • Organic Sweet Potatoes
    Sweet potatoes are a root vegetable that are rich in complex carbohydrates, dietary fiber, beta-carotene and other vitamins. They are a high-quality dog food ingredient. Organic dog food ingredients are free of antibiotics, synthetic hormones, pesticides, chemical fertilizers and artificial preservatives. They are also not allowed to be genetically modified.

  • Organic Chickpeas
    Chickpeas (also called garbanzo beans) are a legume that provides nutrients such as protein, fiber, folate, iron and phosphorus. They are generally a healthy dog food ingredient. Organic dog food ingredients are free of antibiotics, synthetic hormones, pesticides, chemical fertilizers and artificial preservatives. They are also not allowed to be genetically modified.

  • Organic Peas
    Organic peas are a good source of carbs, fiber and protein. Peas are starchy but high in vitamin A, vitamin B6, vitamin C, vitamin K, phosphorus, magnesium, copper, iron, and zinc. We consider this a healthy dog food ingredient. The U.S. Food and Drug Administration (FDA) has warned that there is a potential link between peas and canine heart disease. It is still too early to draw conclusions so we cannot yet say if potatoes are a generally high-quality dog food ingredient or should be avoided. Organic dog food ingredients are free of antibiotics, synthetic hormones, pesticides, chemical fertilizers and artificial preservatives. They are also not allowed to be genetically modified.

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.
