Procter & Gamble's Iams petfood brand added two dry dog food recipes to its Naturals petfood line: Sensitive Naturals, and Simple & Natural.

The Sensitive Naturals recipe contains ocean fish as the first ingredient, Iams says, and is ideal for dogs with ingredient sensitivities. Iams says its Simple & Natural formula contains chicken as the first ingredient for 100% nutrition with no fillers. Both dry kibble recipes also contain rice and barley, along with higher levels of omega 6 and omega 3 fatty acids, natural prebiotic fructooligosaccharides, beet pulp, apple pomace and increased levels of vitamin E, according to Iams.

All of the Iams Naturals petfood recipes are available at pet specialty stores, mass retailers and grocers.
