Hill's Science Diet Adult Dog Food received a mid-tier rating of 3 stars
Hill's Science Diet offers a range of dog food products that are formulated to meet a dog's life stage, lifestyle, or life care needs. The brand's Adult product line, for instance, is designed to help maintain strong, lean muscles and an ideal body condition for dogs aged 1 to 6 years old. Meanwhile, the Adult 7+ range supports energy levels, as well as a healthy heart and kidneys for senior dogs.
The Hill's Science Diet Adult dry product range is made up of 47 recipes with ratings varying from 1 to 4 stars. The average rating of the whole range is 2.5 stars, with some reviews citing its use of grain and non-chelated minerals as the reason for a lower rating. However, it is worth noting that the brand has received a 4 out of 5-star rating from Dogster, with praise for its nutritious formulas that target dogs with health issues.
Despite these positive reviews, Hill's Science Diet Adult Dog Food has also received some negative attention. In 2019, the FDA issued a recall for potentially toxic levels of Vitamin D in 33 varieties of Hill's canned and dry dog food products, including several from the Science Diet and Prescription Diet lines. This issue was resolved as of December 21, 2021, when the FDA terminated the recall. Additionally, in 2014, there was a recall of 62 bags of Adult Small & Toy Breed Dry Recipe due to potential salmonella contamination in Nevada, California, and Hawaii.
Overall, the Hill's Science Diet Adult Dog Food line appears to have received mixed reviews, with an average rating of 3 stars reflecting the range of opinions. While some praise the brand for its targeted nutrition and health benefits, others have expressed concerns over the inclusion of certain ingredients and the safety of the products. As such, it is always important for pet owners to consult with a veterinarian to determine the most appropriate diet for their dog's specific needs.

Hill's Science Diet offers a range of dog food products designed to meet the unique needs of dogs at different life stages, lifestyles, and life care requirements. The brand recognizes that nutritional needs change as dogs age, and their Science Diet line reflects this understanding.
For puppies, the food supports healthy brain development, which is crucial for their formative first year. Adult dogs between the ages of 1 and 6 require nutrition to maintain strong, lean muscles and an ideal body condition. As dogs mature, their nutritional needs evolve. Hill's Science Diet offers food for adult dogs aged 7 and above, which is formulated to support energy levels and promote a healthy heart and kidneys. For senior dogs, aged 11 and above, the food is tailored to support eye, heart, kidney, and joint health, which are common areas of concern as dogs advance in age.
Additionally, Hill's Science Diet takes into account the unique needs of small and large breed dogs. Small and mini dogs have distinct calorie requirements, and the brand offers dry and wet foods tailored to meet these needs. Large breed dogs have higher energy demands, and the food is formulated accordingly to fuel their active lifestyles.
Beyond life stages, Hill's Science Diet also addresses lifestyle and life care considerations. For less active dogs, they offer low-calorie food options to help maintain a healthy weight. The brand's Perfect Weight formula has been successful in helping over 70% of pets achieve weight loss within 10 weeks.

Overall, Hill's Science Diet is committed to providing balanced nutrition tailored to the specific needs of dogs throughout their lives, ensuring they receive the necessary support for their overall health and well-being.

The FDA recalled certain Hill's Science Diet products due to potentially toxic levels of vitamin D
Hill's Science Diet is a line of dog food products manufactured by Hill's Pet Nutrition and marketed under the Hill's Science Diet and Hill's Prescription Diet brands. The products are specially formulated to meet a dog's life stage, lifestyle, or life care nutrition needs. For instance, the company offers different diets for puppies, adult dogs, and aging dogs.
On January 31, 2019, Hill's Pet Nutrition notified the FDA about a report of vitamin D toxicity in a dog that consumed a canned Hill's dog food product. The company then initiated a recall of 25 products. On March 20, 2019, Hill's expanded the recall to include 19 additional canned dog food products. The recall was due to potentially toxic levels of vitamin D in the products. The FDA received additional reports of vitamin D toxicity in dogs that ate certain canned dog foods manufactured by Hill's Pet Nutrition. In response, the FDA requested that Hill's test samples of foods that were not part of the original recall. The company's testing determined that there were additional products affected by the vitamin premix, leading to an expanded recall.
The FDA provided a list of the recalled products, which included:

In very high amounts, it can lead to kidney failure and even death. The FDA asked veterinarians to report suspected cases of vitamin D toxicity through their Safety Reporting Portal or by contacting their local FDA Consumer Complaint Coordinators.

Hill's Prescription Diet c/d Multicare clinical nutrition is formulated to support a dog's urinary health
Hill's Prescription Diet c/d Multicare clinical nutrition is a therapeutic dog food formulated to support a dog's urinary health. Therapeutic dog foods are used to manage specific conditions and require oversight by a veterinarian. They are made with ingredients and nutritional supplements combined in precise proportions to support the health of dogs with particular diseases or illnesses.
Hill's Prescription Diet c/d Multicare clinical nutrition is specifically designed to help with bladder stones in dogs. Symptoms of bladder stones can include bloody urine, straining to urinate, and discomfort. This food can dissolve struvite stones in as little as 7 days and reduce the risk of struvite and calcium oxalate stones. It does this by controlling the levels of magnesium, calcium, and phosphorus and enriching the food with antioxidants, potassium citrate, and Omega-3 fatty acids.
Hill's Prescription Diet c/d Multicare clinical nutrition is also available for cats and is clinically tested to lower the recurrence of the most common urinary signs by 89% and promote desirable urine pH levels. It is formulated to improve lower urinary tract conditions and protect vital kidney function.
Hill's Pet Nutrition offers a range of products under the Hill's Science Diet and Hill's Prescription Diet brands, which are designed to meet a dog's life stage, lifestyle, or life care needs. For example, they offer foods for puppies, adult dogs of different ages, and less active dogs that require a low-calorie diet.

Therapeutic dog food can help manage bladder stones and other health issues
Therapeutic dog food can be used to manage bladder stones and other health issues in dogs. These vet-approved diets are formulated with ingredients and nutritional supplements to support the health of dogs with specific diseases or illnesses. For example, therapeutic dog food can help manage bladder stones, a common condition in dogs.
Bladder stones can be dissolved with special prescription food or medicine, or they may need to be physically removed through surgery or other treatments. A veterinary therapeutic diet that is low in protein and sodium is often recommended to dissolve cystine stones. To prevent cystine stones from returning, a high-protein diet is recommended. Urate stones can be treated with a low-protein, low-purine diet and increased water intake. Struvite stones can be treated with a veterinary therapeutic diet and acidifying foods with moderately reduced levels of protein, magnesium, and phosphorus. Calcium oxalate stones, however, cannot be dissolved with food and require physical removal.
Wet foods are generally preferable to dry foods for dogs prone to bladder stones because they help keep the dog's urine diluted, reducing the chances of stone formation. Increasing water intake is essential in minimizing the occurrence of bladder stones, as it helps dilute the urine and increase urine flow. A raw diet can also help prevent stone formation due to its high moisture content. Additionally, certain herbs, such as marshmallow root and cleavers leaf and flower, can help lubricate mucous membranes and reduce inflammation.
Veterinary therapeutic diets are designed to manage specific conditions and should be fed under the guidance of a veterinarian. They are developed based on extensive scientific research and may be more expensive than regular dog food. Therapeutic dog food can also be used to manage weight, with vet-recommended therapeutic weight-loss foods combining increased fiber, moderate to high protein, and low levels of carbohydrates and fats to help dogs lose weight.
