Of course whenever business interests are involved you can get skewed results, even so called studies. Ever read some 'studies' (read: marketing) produced by Purina? Hilarious! That's why it's important to note the funding parties and if the study is conducted in a scientific way with things like reproducible results and peer review.
That doesn't discount science for me.. Simply how and why it is reported.
You cite being 'in dogs' for x years, where you work, etc, but I don't understand what that adds?
Anyway, I don't really want to argue, so ..
Happy new year and congrats on the Westminster invite too.
