The only thing is with further investigation it may be found many of those "experts" who are against feeding raw may be employed by the company they say you should buy the dry kibble from. At some point during the article there is probably a certain brand mentioned.
I find it hard to believe that a dry, hard kibble that shatters on contact with the tooth, if bitten into at all before being swallowed, can help dental issues.
The article says to avoid by products but again, without paying a huge amount of $$ for a food, the average consumer can not afford to buy the dry kibble that does not contain by products.
The sanctuary that was mentioned at the first of the article - take in abused and neglected animals. Therefore many may already have health issues before arrival. I would be more apt to think many issues were present on arrival.
You can form your own opinions. Most of us do. But I would like to think personal knowledge and experience of people who's pets are on balanced, correctly made raw diets speak for themselves.
