About Watchdog Labs
Nutrition

Nutrition

This food has a good amount of protein but is somewhat high in carbs, which is lowering the fat content slightly 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.


  • Salmon
    Salmon offers one of the highest Omega-3 contents of any type of fish. Raw meat contains about 75% water which is cooked off during the making of dog food. This leaves only a fraction of the protein content in the final product's weight. We recommend looking for dog foods that also include meat meals in the first five ingredients (pre-cooked meat powder that contains four times the amount of protein). Salmon is generally a healthy dog food ingredient.
  • Salmon Meal
    Salmon meal is generally a healthy dog food ingredient. Salmon offers one of the highest Omega-3 contents of any type of fish. 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.
  • Herring Meal
    Herring is an ocean fish that is very high long-chain Omega-3 fatty acids (EPA and DHA). It is also a source protein, fat and other nutrients like calcium and vitamin D. We consider it a generally 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.

  • Menhaden Fish Meal
    Menhanden (also known as mossbunker and bunker) is a marine fish. Menhanden fish meal is generally a healthy dog food ingredient. Fish meals are the result of cooking. Water is removed from the fish meat to create a protein-rich meal powder. Fish meals contain about four times the protein meats do, so generally, they're a good source of nutrients.

  • Dried Peas
    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 peas are a generally high-quality dog food ingredient or should be avoided.

Controversial Ingredients
Castor & Pollux have not included any controversial ingredients in this product.


Country of Origin

Made in the USA.


Meat & Fat Quality

There are four clearly named meat sources in this Castor and Pollux product. They are salmon, salmon meal, herring meal and menhaden fish meal. Named sources imply a higher quality ingredient. Also, there are two clearly named fat sources. Canola oil and ground whole flaxseed tells us source of these ingredients. It’s great to see that all sources of both meat and fat are named.


Artificial Preservatives

There are not any controversial preservatives in this product. 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, there are 11 artificial preservatives  we consider controversial because of their potential link to cancer and other serious health conditions.


Artificial Colors

No artificial colors found in this food.


Artificial Flavors

None found. Not having any artificial preservatives, colors or flavors is great to see.
