This is false in general, and dangerously misleading at best. In particular, some dog foods contain ingredients (bone meal IIRC, but don't rely on that) that can pretty much destroy a human's intestines (which are much less hardy than most animals's because coevolution with cooked food allowed cost-cutting). Pet food sold in California might (might) be required to be safe, but that's dangerously unreliable at best.
Well, when I search human consumption of bone meal I get results saying it might be good or might be bad. There's a risk of intestinal blockage but that takes a whole lot and would happen in dogs too.
Searching is not suggesting any other particularly dangerous ingredients, other than to say it's not great long term. But on a level like "be careful not to get scurvy", not "will destroy your intestines". And that you should watch out for bad storage and still probably avoid raw meat.
