"Natural Balance just recently changed their formula for this food. The old formulas first four ingredients were Potato, Duck Meal, Duck, and Potato Protein.... Now the "New Improved Formula" is Potato, Duck, Potato Protein, Canola Oil....... They claim its better but you can see for yourself that the meat content is far less. Duck MEAL is better that just Duck because just Duck includes water weight. Now its just a bunch of potato, and the potato protein is useless to the dog any ways but boosts the protein content on the bag label so it looks better to the consumer. Disappointed because I used to strongly recommend this product, now I just hear complaints because dogs don't tolerate the formula. Even ones that have been on the old one for years."
