About Watchdog Labs


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

This product has a relatively high amount of calories. It’s important to understand how many calories you are feeding to prevent under or overfeeding. If your dog has fair to low activity levels, you may want to feed less than the labels recommend amount, since high-calorie foods like this are often feed to more active dogs who require a higher amount of daily calories. It's helpful to know that weight loss foods often have fewer than 340 calories per cup, weight maintenance foods typically range from 340-380 calories, and high-activity dog foods are usually over 400 calories.

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.

  • USDA Bison
    Bison is high-quality meat that provides protein, calcium, iron and other nutrients to dogs. 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). Bison is generally a healthy dog food ingredient.
  • Potatoes
    Potatoes provide carbohydrates (mostly starch) and are a rich source of vitamin B6 and vitamin C. The U.S. Food and Drug Administration (FDA) has warned that there is a potential link between potatoes 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.
  • Flax
    Flax (also known as linseed), is a plant that contains high levels of protein, dietary fiber, B vitamins, and dietary minerals. Flax is also very rich in thiamine, magnesium, potassium, and phosphorus. It's unique in that it is one of the best plant-based sources of Omega-3 fatty acids. We consider it a high-quality dog food ingredient.

  • 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.

  • Carrots
    Carrots are a root vegetable and contains healthy nutrients like carbohydrates, fiber and beta-carotene. We consider it a high-quality dog food ingredient.

Controversial Ingredients
Grandma Lucy has not included any controversial ingredients in this food.

Country of Origin

United States

Meat & Fat Quality

Grandma Lucy’s is clearly labeling the meat source as “USDA Bison” in this product. This is great because it shows you the specific source the ingredient comes from. They are just as clear with the fat source flax. Having meat and fat sources clearly named is a great sign of quality.

Artificial Preservatives

This Grandma Lucy’s product does not contain any 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 are in this product.

Artificial Flavors

No artificial flavors are in this product.
