Purina Pro Plan and Hill's Science Diet are two prominent brands in the pet food industry, often recommended by veterinarians and available at similar price points. Both companies have a long history and offer a wide range of products for dogs of all life stages and with specific health needs. This article delves into a detailed comparison of their ingredients, formulas, recall history, and overall suitability for your canine companion.
Overview of Purina Pro Plan
Purina Pro Plan is a popular line of dog food manufactured by Nestlé Purina PetCare Company. It is known for providing nutritious food for dogs of all ages and with specific dietary requirements. Purina has been around since 1894 and has evolved its formulas based on extensive research.
While Purina Pro Plan uses high-quality ingredients, it is a premium-priced brand. Some recipes include meat by-products, which some pet owners may find less desirable. However, each formula is carefully crafted and backed by research, containing healthy proteins like fish, chicken, turkey, beef, and duck.
Purina Pro Plan offers both dry and wet food options, and it also has a special Veterinary Diets collection for dogs with specific health issues, such as cognitive health, digestive health, food allergies, sensitivities, and urinary tract health.
Purina Pro Plan Recipes Examples:
Purina Pro Plan Adult Beef & Rice Formula: This essential diet is suitable for healthy dogs without chronic conditions. It contains vitamin A and omega-6 fatty acids for healthy skin and coat. The first ingredient is beef, but the recipe also includes poultry by-product meal, fish meal, and dried egg product.
Purina Pro Plan Puppy Chicken & Rice Formula: This recipe is designed for puppies and contains glucosamine and EPA for joint health and mobility. Chicken is the first ingredient, and the gentle formula is easy on a puppy’s sensitive stomach. It contains beef and fish, which may not be suitable for puppies with allergies. Garlic oil is listed as the last ingredient, which is a controversial ingredient.
Purina Pro Plan Sport Performance 30/20 Formula: Ideal for active dogs, this recipe contains 30% protein and 20% fat to support metabolic needs and muscle maintenance. It includes amino acids, EPA, and glucosamine, beneficial after strenuous activities. This high-calorie recipe is specifically for active dogs.
Overview of Hill's Science Diet
Hill's Science Diet is another globally recognized, vet-recommended brand. Similar to Purina Pro Plan, it offers specialized diets for dogs of all life stages and health concerns, with over 40 unique recipes in both dry and wet forms. These recipes cater to specific diets, such as sensitive skin and stomach, weight management, and oral care. Hill's Science Diet aims to provide consistent nutrition throughout a dog's life.
The majority of Hill's Science Diet dog food contains healthy grains like barley and brown rice, which aid digestion and provide fiber. Grain-free options are also available for dogs with grain sensitivities.
Hill's Science Diet Recipes Examples:
Hill's Science Diet Adult Chicken Recipe: This popular recipe is for adult dogs, promoting healthy skin and coat and supporting the immune system. Chicken is the only animal protein, making it suitable for dogs with beef allergies.

Recall History
Both Science Diet and Purina Pro Plan have faced recalls over the years. Analyzing these recalls offers insight into the safety and quality assurance measures each brand implements.
- Purina Pro Plan: In March 2016, there was a recall in Pro Plan Savory Meals due to inadequate vitamins and minerals. In 2015, Purina faced a lawsuit over allegations that its Beneful brand (another line, not Pro Plan) contained substances that could harm or even kill dogs. The plaintiff claimed that propylene glycol, an FDA-approved food additive used in the brand, was dangerous for canine consumption. The suit also alleged the presence of mycotoxins, harmful substances produced by mold found in grains. Purina denied the allegations, and the lawsuit was eventually dismissed.
- Hill's Science Diet: In March 2007, the FDA recalled over 100 brands for containing traces of melamine, and Hill’s Science Diet was included in this mass recall. There was another recall in November 2015 for its canned pet food, but the reason is unclear. The most recent recall was early in 2019. In recent years, Science Diet hasn’t been a prominent target in major lawsuits related to its pet food products.
Science Diet’s recalls, particularly concerning the excess Vitamin D incident, show the brand’s proactive approach to potential health concerns, even when the risk might seem minimal. Their transparency in these situations underscores their commitment to pet safety.
Purina Pro Plan’s recalls highlight a similar dedication to pet health. While the lawsuit concerning Beneful raised concerns, it’s essential to differentiate between different product lines under the Purina umbrella. Pro Plan, as a distinct line, has maintained a relatively strong safety record.
Veterinarian Influence and Brand Ethics
Many veterinarians receive nutrition education directly from large pet food manufacturers like Hills and Purina. These companies sponsor veterinary schools, provide research funding, and even supply clinics with free food samples.
Nestle (Purina), Mars (Royal Canin), and Colgate-Palmolive (Hill’s Science and Prescription Diets) are big consumer packaged goods companies. They need to grow the profit margin on the products as required by all public companies. Those companies influence AAFCO (Association of American Feed Control Officers) and WSAVA (World Small Animal Veterinary Association) on pet food requirements to adhere to their standards. Those regulations allow them to use low-quality ingredients such as diseased animals transported in open trucks without having to reveal it to the consumer.
Contrary to common belief, those companies have multiple records of issues related to quality control. See Hill’s recall due to an overdose in their prescription food that is known to cause kidney and heart failure (and have caused deaths). Some of them don’t necessarily show high ethics in their actions. Look it up: both Mars and Nestle supply chains used companies involved in forced labor, human tracking and child labor. Mars purchased cocoa beans from farms notorious for children's labor. Mars has Federal Trade Commission charges for making false advertising health claims.
AAFCO Nutrient Requirements for dogs don’t list minimum requirements for carbohydrates or fiber. The high carbohydrate content is needed for the extreme heat and high-pressure extrusion processes in order to hold the kibble together. That’s why kibble is typically 30%+ carbohydrates and the main reason for adding carbs. It also makes the food’s shelf life stable, lasts longer without freezing or refrigerating and allows for cost savings (corn cost is very low compared to the cost of meat). Your pets pays the price for it! High carb diets may lead to issues related to the overproduction of yeast, itchiness, red staining, ear infections, skin issues, altered gut flora, obesity, and bad breath.
For example, Hill's Prescription Diet i/d Digestive Care Low Fat Dry Dog Food includes ingredients like Brewers Rice, Corn Starch, Corn Gluten Meal, Whole Grain Wheat, Chicken By-Product Meal, Flaxseed, Cracked Pearled Barley, Whole Grain Oats, Dried Beet Pulp, Chicken Liver Flavor, Pork Flavor, Lactic Acid, Ginger, and Soybean Oil. This list shows that there is no meat in this food.
Conclusion
