Hill's Science Diet Adult Light with Liver is a mid-priced wet dog food with overall lower quality. This product has 3 controversial ingredients, which includes an artificial flavor. The food has a high amount of carbs compared to its protein and fat content, but excellent meat and fat quality. Hill's Pet Food has an above-average number of recalls. The company, however, was mostly transparent when answering our questions.Read the Full Review Below
The food has high carbs and low protein and fats, making it less nutritionally balanced compared to other dog foods we evaluated. Carbohydrates are cheap so they keep the food’s cost low and 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

Country of Origin
Hill’s dog food is made in the United States, which ensures a high level of food quality standards.
Meat & Fat Quality
Pork By-Products, Pork Liver, and Soybean Oil - all meats and added fats are clearly showing which animals (and plant) they are made from, that’s transparent and good.
This product contains no 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.
No artificial colors, either. That’s great.
Chicken Liver Flavor is used in this dog food. That’s an artificial flavor that’s unnecessary and controversial. The food would be better without it.
Hill’s has an above-average number of dog food recalls. Here are more details.
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.
