About Hill's Science Diet Brand
Hill’s Science Diet was established in the 1960s but has roots going back to the 1930s when Dr. Mark Morris Sr., a visionary veterinarian, developed a therapeutic diet for dogs suffering from kidney disease. His journey began when he observed that dietary changes could potentially alleviate certain chronic health issues in pets, leading him to create the first “Prescription Diet” for a seeing-eye dog named Buddy, who suffered from kidney problems. Partnering with Hill Packing Company in Topeka, Kansas, Dr. Morris worked to manufacture this specialized diet, laying the groundwork for what would become Hill’s Pet Nutrition.
In 1976, Hill’s Pet Nutrition was acquired by Colgate-Palmolive, allowing for expanded research, distribution, and innovation. This acquisition facilitated further advancements in pet nutrition and led to the development of the Science Diet line, which focuses on life-stage and condition-specific formulas grounded in scientific research. Hill’s employs a large team of veterinarians, scientists, and pet nutrition experts at its global Pet Nutrition Center in Kansas, where they conduct research to enhance pet well-being through dietary solutions. Hill’s Science Diet today offers products tailored to various needs, including age, breed size, and specific health concerns such as digestive health, weight management, and mobility support.
With a reputation built on quality control and scientific backing, Hill’s Science Diet is one of the most trusted brands in veterinary-recommended pet food, emphasizing both clinical research and ingredient quality. This commitment has helped the brand stand out as a leader in the pet food industry for decades.

negative report
However, with the rise of social media and increasing consumer feedback, Hill’s Science Diet has also faced serious negative publicity. First, criticisms regarding ingredient quality have garnered widespread attention. Some consumers have pointed out that certain formulations contain low-quality fillers, such as corn and soy, which may not provide the optimal nutrition pets require. Additionally, in 2019, the brand issued a recall for some canned dog foods due to elevated levels of vitamin D, raising concerns among pet owners about the brand’s quality control.
Moreover, despite many veterinarians recommending Hill’s Science Diet, some consumers have expressed skepticism. They believe that these endorsements may be influenced by the financial relationships between the brand and the veterinary industry, rather than based on independent professional judgment. This perception has contributed to a divide in the brand’s image, leading some consumers to lose trust in its products.
Social media has also seen an influx of negative reviews, with many pet owners sharing experiences of their pets encountering health issues after using Hill’s products, such as digestive problems and decreased appetite. These negative experiences have spread quickly, further impacting public perception of the brand.
In summary, while Hill’s Science Diet holds significant influence in the pet nutrition industry, the emergence of negative publicity serves as a reminder for consumers to remain vigilant when selecting pet food.
