I think everyone has meet someone who is, for want of a better term, a "Net Doctor".  The internet is a massive resource, which I, as a Vet use on a daily basis.  There is certainly lots of information out there, so much so that it is often hard to pick the diamonds from the rest of the rubbish.  So here are some broad tips to help.

    1.  Start looking with a healthy degree of skepticism. Be critical and look for inconsistencies in what you are reading.  Science is not art (although some parts appear very similar)

    2.   Look for reference, online citations to veterinary journals etc,  ask the e-author to substantiate the claims that they make.

    3.  Use reliable sources.  In general if the site is also a shop or sells a product, I think that the information they provide has to be judged more harshly than those that are just informative.

    4. Well written and presented does not mean its right!.  Cross check anything you read.   

    5.  Who is writing the article? If there is an article written by a drug company explaining why thier product is so much better at treating a condition that any other - you have to be skeptic.  Look for peer reviewed content.  

    6.  Finally, Testimonianals are not scientific evidence.  The for the most part are advertising.  Anecdotal evidence is used occassionally in formulating veterinary therapies, but in general a large part of the veterinary community agree's the therapy is probably useful and certainly not harmful prior to it being used.

I have given a few sites below to start looking at to help you with your searches.  Please send me any more that you think appropriate.
