Natural Balance Pet Foods Inc.  is expanding its petfood offerings with new canned and treat formulas in its  L.I.D. Limited Ingredient Diets line . The line is designed for dogs with sensitivities to common petfood ingredients.

"We're constantly striving to offer more options for pets, particularly those with special dietary needs," said Heather Govea, senior vice president of sales and marketing at Natural Balance.

The two new canned formulas and three new treat formulas will create complete diets of three existing L.I.D. lines for dogs: Sweet Potato & Bison, Lamb Meal & Brown Rice and Sweet Potato & Chicken.

Along with the expansion of the L.I.D. collection, Natural Balance is re-branding the complimentary treat line with new packaging and a new name:  L.I.T. Limited Ingredient Treats .

The new additions are scheduled to be available in stores by the end of May.
