In this Mythbusting episode, Mark and Rowan are discussing the topic that Dogs can't eat vegetables.

They discuss that most people are following a strict evolutionary based diet and are trying to do the best by their dog.

They then go on to discuss the study that dogs with a host of bacteria in their guts live longer, healthier, happier lives. So, therefore, the vegetables might not be digested and fed by the dog but with feed the bacteria.

Lastly, they talk about how there is a high percentage of foreign genetic material in dogs and even humans.
