General Mills’ pet-food business was an unexpected bright spot in the food maker’s otherwise dark fiscal 4Q, rebounding from several tough quarters before that, but fiscal 1Q has put the unit back in the dog house. The segment delivered flat sales as a 5% increase from pricing and mix was offset by a 5% drop in volumes. Sales of dry pet food were up in the mid-single digits, but roughly flat for wet food and down double-digits for pet treats. The segment’s operating profit was down 10% at $111M, primarily due to lower volume, higher input costs and higher overhead expenses.
