I wonder if dog nutritional guidelines are based on the idiotic and never-empirical FDA guidelines.
I wonder how much, if any, actual research has been done into optimal dog diet. When you look at the huge spread of ideas even with regard to people, you have to assume very little.
Historically what would they have eaten? I would think, after domestication, whatever the humans around them ate. If one buys into the Paleo diet, then–as I somewhat do–then dogs ought to eat Paleo (meat, veggies, some fruit, some nuts and fat, no sugar or bread).
My two are getting older, and one has a nasty cough that is seemingly related to some aspect of aging I didn’t really understand. She is on blood pressure meds and a diuretic, but her cough just got worse, and I’m wondering if it’s because I changed dog food.
