I'm torn. My dad's a dr. and my mom's a DNP, so I sympathize with the fact that people that don't have required background use unsubstantiated or substandard sources and consider themselves "expert" in a given field.
On the flip side, I recognize that individuals have a more vested interest in themselves (and, by extension) their pets than drs, nurses, and vets do. So often serious illness masks as something dismiss-able, or it takes a long time for science to catch up to anecdote. Lobbying and bribing are rampant in both fields too.
Kudos to this vet for staying away from the stuff of flame-wars though. It seems unfair to take issue with her for something she (deliberately, I'll bet) didn't touch with a ten foot pole.
