I have used blue life protection for my dogs for nearly a year. Recently we switched to blue wilderness for more flavor choices for our dogs. After switching to the wilderness formula my dogs started getting sick and my younger ones could not kick the illness. After spending nearly 600 on the vet visits and medications we discover they had contracted parasites and had digestion issues! We switched them to a special diet and with that and the medication they got better. We decided to give blue wilderness one last chance and after about 2 days of eating it they are sick again. I keep my food in a sealed container so I do not have the bag for the batch information but I am very disappointed with blue dog food.
