I don't think it was one-sided - I didn't say it was a bad way to feed dogs and I wasn't suggesting that raw-fed cannot be healthy. I was saying the same as you have said above, that, as far as I know, there is no good evidence to suggest that feeding raw produces a healthier dog than other methods. In my view, if you take on extra risks, albeit relatively small risks, there ought to be a significant benefit at the end of it.
In your own description, William's health may well have improved but the problems might have been due to something in the kibbles that caused dietary intolerance and not be specifically related to raw food. I do agree with your worry about people taking raw feeding on without the knowledge to ensure that they are providing a balanced diet, however, I must say that this forum usually seems to suggest that this is not a difficult thing to do. I recently posted a quote from Marg Chandler from Edinburgh Vet School who said:
" in years as a veterinary nutritionist I have checked many homemade diet recipes and programmes and none of them were balanced for the essential nutrients."
yet this didn't seem to cause any reaction. If I were feeding raw I would certainly firstly accept that someone with her experience is likely to know more than me and take it seriously, and secondly, want to know more about the potential issues.
My problem with all of this is that the benefits are often oversold on the basis of anecdote, and the potential problems under-played. Identifying genuine improvements in health and what causes them is fraught with difficulty. Humans are very susceptible to confirmation bias. If someone invests emotional belief in a particular course of action, and backs it up by spending money, they will interpret any change as confirming their decision. Even if there is no change they will often see things that are not there and become convinced that their actions have been successful. That is why scientists insist that blinded random controlled trials are necessary to produce good evidence and that anecdote is very poor quality evidence.
I will happily change my views if the evidence changes. Unfortunately, people who operate by belief in a particular philosophy often take the opposite view and treat the evidence as a direct attack on their position and see conspiracies all around them.
If the health changes are as dramatic and universal as they appear to be given the claims in this forum, I would expect vets up and down the country to be shouting out about its benefits. I don't see that. The fact that vets are more accepting of it is probably related to the fact that if they are faced with an owner who has been convinced by, let's be honest, the unsubstantiated hype that comes out of some of the more extreme web sites, they face up to reality and bend with the wind.
For me too much hype, too many specious arguments and the jury is still out.
