Hill's Science Diet

Hill's Science Diet and the Biology of Health

In 1939, a blind man named Morris Frank asked a veterinarian for help. His guide dog, Buddy, was dying of kidney failure. Dr. Mark Morris Sr. believed he could save Buddy by changing his diet. He and his wife Louise went into their kitchen and cooked a new food with low salt and high-quality proteins. Buddy recovered, and that kitchen experiment grew into Hill's Pet Nutrition. Today, this company is one of the only brands that treats pet food like medicine.

Most pet food companies focus on marketing trends. They might follow the latest fad like "grain-free" or "ancestral" without knowing if it actually helps pets. Hill's Science Diet takes a different path. They employ over 220 veterinarians, nutritionists, and food scientists to study what pets need at a cellular level. They do not just guess what ingredients work. They study how food affects a pet's genes and biology.

This brand is for the owner who trusts experts. If you want a food that has been tested in clinical trials, this is your answer. It is for the dog with a sensitive stomach who cannot handle rich foods. It is for the cat who needs to lose a few pounds to stay active. Hill's delivers nutrition that is boringly consistent and scientifically proven to work.

Why Hill's Science Diet Works

• Predictive Biology
  We use genomics to understand how specific nutrients affect your pet's gene expression. This helps us switch your pet's body from storing fat to burning it.

• ActivBiome+ Technology
  Our scientists discovered a specific blend of prebiotics that feeds the good bacteria in your pet's gut. This supports a healthy microbiome and improves digestion in just seven days.

• Clinical Testing
  We do not rely on theory. We feed our foods to pets at our Global Pet Nutrition Center to verify that they actually deliver the health benefits we promise on the bag.

• Veterinarian Recommended
  More veterinarians feed Hill's to their own pets than any other brand. They know that our safety standards and quality controls are some of the strictest in the world.

Top Hill's Science Diet Formulas

Adult Perfect Digestion™

This formula focuses entirely on the gut. It uses our exclusive ActivBiome+ blend of prebiotics to feed the unique microbiome living inside your pet. Owners often see perfect poop in just one week. It is the best choice for dogs and cats with irregular bathroom habits or sensitive stomachs.

Adult Sensitive Stomach & Skin™

This is one of our most popular recipes for a reason. It uses highly digestible ingredients like chicken and rice that are gentle on the digestive tract. We also load it with Vitamin E and Omega-6 fatty acids to nourish the skin. We recommend this for pets who suffer from loose stools or itchy, flaky coats.

Adult Perfect Weight™

Obesity is a major health crisis for pets. This food uses a specific blend of fibers and ingredients to kickstart your pet's metabolism. It helps them burn calories rather than store them as fat. It allows your pet to feel full and satisfied while still shedding the extra weight that hurts their joints.
