Use of named meat meals as primary protein source

Hill’s Science Diet Dog Food has named meat meals as a key part of its makeup. Chicken meal, packed full of protein and minerals like phosphorus and calcium, is the first thing on this food’s list.

Bones in meat meals offer these good things for your pet’s health too. Often, meat meals come with high-quality protein that dogs need to stay strong and healthy. Foods like Hill’s Science Diet Adult use both plants and meats for a well-rounded meal option.

Some even have extra special proteins such as duck meat! It gives not just protein but also fat and other body-boosting minerals to keep your pet at their best.

Inclusion of grains in some recipes

Hill’s Science Diet dog food has grains in it. These are things like whole grain corn and soybean meal. They make the food healthy for dogs to eat. All grains are not bad, some lend a helping hand to your pets’ health.

The Adult Plus type of this dry dog food also has grains in it. Grains can be good for your pet if they don’t have any allergies or stomach problems from them. Some foods have legumes, but you can’t tell just by the name on the bag if those are there or not.

Nutrient Analysis

We’re diving deep into the nutrient content of Hill’s Science Diet products, examining the guaranteed analysis for key nutrients to ensure they meet AAFCO standards. Our review also focuses on their commitment to traceability and transparency in sourcing ingredients.

For regulators, this analysis is essential to ensure Hill’s Science Diet meets certain pet food standards. However, it’s worth noting that the guaranteed analysis does not provide information on all nutrients and ingredients within the food. 

So, while it’s useful as a starting point, it shouldn’t be the only determining factor when choosing a pet food.

Despite these limitations, the Guaranteed Analysis still offers valuable information. It allows pet owners to compare Hill’s Science Diet with other brands in terms of basic nutrition levels. 

But it’s always advisable to look at the overall quality and source of ingredients, alongside specific health needs of your pet for a holistic dietary choice.

Any past recalls and reasons for them

Hill’s Science Diet had some recalls in the past. In June 2014, they pulled back 62 bags of Adult Small & Toy Breed Dry Dog Food. They thought there might be Salmonella in it. Then in March 2019, Hill’s Pet Nutrition recalled canned dog food.

This was because they found too much vitamin D in them. The FDA reported in January 2020 that Hill’s did not check their pet food ingredients well enough all the time. Later in 2019, more canned dog food products were recalled by Hill’s due to high levels of vitamin D again.

Feeding Guide And Tips

Discover how to ensure proper nutrition for your pet with Hill’s Science Diet including recommended feeding guidelines, transitioning tips, and advice for dealing with picky eaters.

Recommended feeding guidelines

Feeding your dog right is key. Follow these rules to make sure your pet gets the best meal:

  1. Check the feeding guide on Hill’s Science Diet bag. It will give you a good start.
  2. Make sure you know your dog’s weight. This helps you know how much food to give them.
  3. Puppies eat more than adult dogs. They grow fast and need more food.
  4. Adult dogs don’t eat as much as puppies. But, they still need enough food to stay fit.
  5. Don’t let your dog miss meals. Keep meals in their daily routine.
  6. The pet food feeding guide can change sometimes. Always check it before you feed your pet.
  7. Talk to your vet if you’re not sure about something, like how much food to give or what kind of food is best for your pet’s health.

How to transition to a new food?

Switching to a new food needs a careful plan. The steps below can help keep your pet safe and happy during this period.

  1. Make a slow transition: Dogs do not like quick changes, especially in their diet. A sudden change can mess up their stomachs and cause upset belly issues. A gradual move is best.
  2. Talk to your vet: Your vet knows your dog better than anyone else. They can help you choose the right food and guide you on portion size.
  3. Take seven days to switch: Start by mixing the old food with a tiny amount of new food on day one. Then slowly increase the amount of new food each day, while reducing the old food, over seven days.
  4. Be patient: Changing diets takes time for dogs to get used to it. Be calm if your dog isn’t too eager or seems unsure about the new grub.
  5. Plan proper portions: Don’t guess how much food to give your pet! It’s crucial to measure out meals so they’re getting just what they need.
  6. Watch for digestive issues: Keep an eye on your pet for any signs of an upset belly, vomiting or loose stools during the changeover process.
  7. Use feeding guide tips: Different foods may have different feeding guides based on size, age and activity level of your dog.
  8. Reinforce good behavior: Every time your dog eats the new diet without fuss, reward them with praise or even a small treat!

Tips for feeding fussy cats and dogs

Feeding fussy cats and dogs is not easy. Here are some tips for you:

  1. Dish out small meals: If your pet is picky, they may like to eat smaller meals. Offer food four times a day instead of two big ones.
  2. Heat up the food: Warm food smells more. Getting your pet’s nose going can help them want to eat.
  3. Mix wet and dry food: Some pets like the mix better than just dry food.
  4. Get rid of uneaten food: Do not leave uneaten food in the dish for too long. It can start to smell bad.
  5. Try different foods: Cats and dogs have their own likes too! If your pet does not like one kind of food, try a different one.


We finalize this Hill’s Science Diet review with our endorsement as it showcases impressive dedication to pet health, diverse product offerings and strong veterinary backing.

However, we emphasize the importance of individual pet needs and encourage owners to consider their pets’ dietary requirements before making a feeding decision.

Pair your understanding of your pet’s specific nutritional requirements with Hill’s commitment to science-backed formulas for effective results.

Continue looking out for recalls and always consider reviews and feedback from other users for a better-rounded perspective in picking the best diet solution for your four-legged friend.

The ultimate goal is not just good nutrition but also ensuring its suitability for your beloved furry pals’ unique digestive health needs.

Overall assessment and recommendation

Hill’s Science Diet seems fair when we look at what is in it. The food gives a good amount of dry matter protein. But, the FDA is looking into a link between this food and heart problems in dogs.

Dogs may get dilated cardiomyopathy (DCM). Such news can make dog owners worry. It’s wise to watch your pet’s health very closely if you’re using this brand of dog food.

Final thoughts and considerations.

Choosing the right food for your pet is key. Hill’s Science Diet offers a range of options, from meals for weight loss to foods for those with sensitive skin. Their products aim to give pets the nutrients they need.
