When pet food producer “add taurine” it is in the form of a synthetic powder manufactured in China.

As an alternative, one can feed taurine-rich foods like beef heart.

In the current commercial dog food mess, people turned away from foods containing grains because carbohydrates in a canine diet and plant-based proteins are not optimal. To market to those consumers many manufacturers simply replaced carbohydrates and plant-proteins from grains with non-grain plants.

Some of those alternative ingredients may interfere with taurine absorption/conversion, but that doesn’t suddenly make “grains” a desirable dog food ingredient.

Canines did not evolve to thrive on eating cereal-based diets. There is no mystery why these issues keep cropping up. You have healthy dogs when they are fed a species appropriate diet. Otherwise, not so much.
