Product Development

Dogs At Hill’s™, Over 200 veterinarians, food scientists, technicians and specialist nutritionists are continually expending the Science Diet™, Prescription Diet® andIdeal Balance™ branded pet food ranges to meet the needs of your pets when they are in optimal health or  when they are sick. These specialists ensure all Hill’s™ food recipes are balanced for over 50 pet diet nutrients, and most importantly, that pets LOVE their food.

Some important dietary nutrients – the Hill’s™ way

• Hill’s™ high-quality raw ingredients, including specific lean proteins which maximises nutrient absorption and reduced waste output as faeces.

•  reducedlevels of phosphorus, as high levels of phosphorous can be associated with renal disease.

•  added taurine:  taurine is an “essential amino acid” – meaning that it must be provided in the cats’ diet; taurine deficiency, which is common in home-cooked diets is known to result in blindness, tooth decay and heart disease in cats.

•  ideal levels of important antioxidants: antioxidants help combat the damaging effects of free-radicals, which are substances produced during normal metabolism but which are unstable and can damage normal cells. Antioxidants therefore play an essential part in the immune system of all animals, helping to resist infections, reduce the risk of developing cancer, and moderate allergic skin conditions.

Dog and Cat

In a wild diet, antioxidants are sourced from vegetables and fruits, and include vitamins A, C and E, and selenium; in pet diet formulation, antioxidants are present in natural plant-based ingredients, and are also boosted as supplementary ingredients.

•   essential fatty acids – another range of nutrients which must be provided in the diet of animals; omega 3 and omega 6 fatty acids are important in the normal function of virtually every body system, from the heart to the immune system, joints, organs and skin /coat. Once again, these nutrients can be found in the natural raw ingredients in Hill's™ diets, and are further supplemented to ensure the nutritional requirements of cats and dogs are met.
