My little lady loves this food and it is only 1 of two brands I use - my dog has petit mal seizures and has had them for many years - Had lots of them at first, wen ton medication which helped a bit but once I put her on food without chemical fillers and such she got much better - now only has them on rare occasions Can't prove a direct effect from the food but it sure seems to be a contributing factor to her having very few bouts. Besides she loves the product.
