Hi Karen-
I believe that the creator of the list actually called the companies listed to find out what the max calcium levels are of the foods listed on the sheet. I feed both with and without grain foods to my labs. I wouldn’t feed a food with rice everyday forever due to potential arsenic, but part of a rotation is OK in my opinion.
I’ve been learning that waiting until the dogs are full grown to neuter is also helpful for preventing hip dysplasia as well. Unfortunately, I had my dogs neutered younger due to vet’s recommendation before I knew better. Luckily, they are three years old now and are doing fine.
Science diet is a controversial brand on this site. It just seems very expensive for the ingredients listed to me.
Take care!
