Animals (human, and non-human alike) need nutrients to survive. They don’t need those nutrients to have come from some other poor animal, and carnists that insist that is the case are engaging in anti-science magical thinking. We can do amazing things with science, including synthesizing almost anything you can imagine.

However, last I looked around for plant-based dog food, it was pretty heavy on lentils, which I’ve heard can cause heart enlargement in dogs. Have further studies been done on this, or, have plant-based dog foods that don’t rely on lentils been made available?
