Hi Patricia- Yes, science is ever changing. However, the sources you are choosing to follow as far as I know, have no background or education in the science of veterinary nutrition. Susan Thixton is an activist and has done some good work as far as safety in the pet food industry. Which, lord knows we need! However, she has no credentials to rate dog food.
There are brands that employ many PhD’s in veterinary nutrition and do research and testing on their foods to make sure they are digestible and providing all the nutrition our dogs need. Their ingredients just may not look as appealing as some of these new boutique foods that are all the rage now.
Like it or not, the big companies are employing experts, do research, testing, and own their own manufacturing facilities. And, most importantly, do not have any dogs so far with diet related cardiomyopathy.
