Anecdotal evidence: My Sheba has been on a plant-based diet for a few years now. She is surprisingly fit and healthy for a large dog her age (12+ years). And has a shiny coat, too. I feed her a combination of Veganpet dry food and cooked vegetables with lentils and barley/rice/polenta.

There is not much choice in plant-based commercially produced cat and dog food in Australia. Though I'm very happy with the brand I use, #Veganpet. I order the 15 kg bags online, and it's delivered to my front door by Australia Post.
