I don't think you should look negatively at your vet because of this newsletter. It's his opinion and he does has his points, cause it is based on his experience.
As for BARF, I understand the benefits of it since it really is more of a natural diet, but there is the worry of handling raw meat.
Not only are you handling it when preparing the meal, but there's also the dog being the carrier of the raw meat bacteria, like via saliva (doggy kisses) and what not.
I guess BARF would be the way to go if you are REALLY careful and make sure there's no cross-contamination.
Just my opinion.
(I hope I don't get bombarded by the BARF users) lol
