Hill's Science Diet Adult Perfect Weight is a mid-priced wet dog food with overall lower quality. This product contains 5 controversial ingredients, including an added artificial flavor. The food has a high amount of carbs, compared to its protein and fat content, but excellent meat and fat content. Hill's Pet Food has an above-average number of recalls. The company, however, was very open and transparent when answering our questions.Read the Full Review Below
This food has a fair amount of protein but it’s high in carbs, which is lowering the fat content 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 an below average amount of calories for wet food. It’s important to understand how many calories you are feeding to prevent under or overfeeding. Based on your dog's current weight and activity level you may want to feed more or less than the recommended amount. This is a weight-loss dog food so this makes sense in that context.

The average dog food we reviewed has 39 total ingredients, with 1 controversial ingredient. This product has 5 total controversial ingredients and 1 of them is found in the first five ingredients. This is concerning because the first 5 ingredients make up most of the product.
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.
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 Liver, Chicken and Coconut Oil are transparently showing their origin. However, this food also contains more genetically labeled Fish Oil, which leaves you to speculate what animal this comes from specifically. So overall, the quality of meats and added fats is somewhat mixed here.
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 really great.
Chicken Liver Flavor and also Egg Flavor are used in this dog food. Both are artificial flavors that are unnecessary and controversial, see above. The food would be better without them.
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.
