Come on, Robinson!
You stated that pet owners know when something works for their pet.
I challenged this, giving specific examples of situations where pet owners were entirely wrong about whether something was "working" for their pet.
You rejected these examples, saying that anecdotes meant nothing, and where were my scientific studies. Well, I produced one, but requested that you provide the scientific studies you were relying on for your original statement.
Deafening silence.
You also changed your ground to claim that pet owners can tell when their pets clinical signs have improved. I challenged this one as well, including a published reference.
As you reject anecdote as worthless (even, apparently, anecdotes which clearly refute a general/universal statement), then obviously you must have scientific studies which show that pet owners know when "something works", and they also know, reliably, when their pets' clinical signs have improved. Or you would not have made these statements.
I'm still waiting!
(Actually, I wouldn't be surprised if you could find several articles available urging vets to pay more attention to what the pet owners tell them. This is because, given that pet owners are so damn unreliable so much of the time, many vets get into the habit of discounting just about every word the owner tells them. Clearly this is not good - owners sometimes have valuable insights, and losing these by too cynical an attitude is bad medicine. But actually, the fact that this problem exists, simply underlines my original point.)
