The PEDIGREE Dry Recipes are our best recipes ever, and are specially formulated to meet the four Universal Needs of Dogs: Skin & Coat, Oral Care, Digestion, and Immunity. SKIN & COAT The PEDIGREE Dry Recipes will nourish a dog's first line of defense—its skin & coat—by including leading levels of Linoleic Acid and optimum levels of Zinc, which have been identified as two of the most important nutrients for helping dogs maintain a healthy skin and coat. ORAL CARE Several PEDIGREE Dry Recipes include a patented Oral Care kibble. This kibble will provide oral care benefits by promoting chewing and mechanical cleaning action that helps reduce plaque and tartar buildup, a contributor to gum disease (the number one health issue for pet dogs today). The Oral Care kibble is available in select varieties. Puppies have different needs because they are learning to chew and are developing new teeth. The oral health emphasis in PEDIGREE PUPPY is focused on tooth development by optimizing calcium and phosphorus. The crunchy texture of PEDIGREE PUPPY also helps reduce plaque and tartar buildup. PUPPY FOOD Our special care products (PEDIGREE Healthy Joints, PEDIGREE Healthy Weight, and PEDIGREE Healthy Longevity) provide the professional nutrition of the improved dry recipes, but they were launched prior to the final development of the Oral Care kibble. However, the special care products, like all of our products, contain the right balance of calcium and phosphorus for strong healthy teeth and a crunchy texture that also helps reduce plaque and tartar buildup.

Highly digestible meals, balanced with the right blend of fiber, can lead to overall digestive health, optimal nutrient absorption and less waste. Finally, PEDIGREE Dry Recipes will help support a dog's immune system through the addition of key antioxidant nutrients vitamins E and C. Supplementation of vitamins E and Vitamin C together have synergistic benefits to promote a strong immune system and to help protect every cell in your dog's body, as the WALTHAM Centre for Pet Nutrition's research has shown.
