We have effectively been put completely out of business by this and our site contains 100% original content.  I wish someone could take a look at our site which is dermapaw.com and tell us why this might have happened. This is devastating.

Miki, please read the article pointed to as it explains in great detail that complaining won't help, while also giving actionable advice on what to do to get your Google organic traffic back.

Having content (unique or not) reproduced on mutli sites is page of this update and is more than likely the problem for you.  I simply took a snippet from your home page and you can see the same snippet on 6 different URLs.  Shoot me a message I might be able to help explain more.

Good Point, I also ran a copyscape report and it is showing useful data http://copyscape.com/?q=http://dermapaw.com

The other thing the site can benifit from is looking into breaking up your content a bit more.

@MIki - seriously, if your business and livlihood is at stake, hire a professional. I seriously doubt that anyone here is going to give a thorough analysis for free.

@Jaan - while that is kinda problematic, who's the originator of the content? All in all this update has some SERIOUS issues. Sure, nothing I work on was spanked, only growth, but I have seen a TON of data from people coming to me privately. It was actually the first update that was supposedly dealing with attribution (and scrapers). Even that one didn't work as advertised. Point being, don't send this person down that road without being absolutely certain. Bad form 'ol chap... oui?

@Jill - sorry for the complaint@everyone else, thank you for all of your input; we were as close to a non-profit organization as you can get without technically being one, because our goal was to offer people an inexpensive alternative to the expensive vet treatments, therefore keeping our prices as low as possible, hence we cannot afford a 'professional'.  The comments from the Google webmasters I received, were opinions on our product and not technical search advice or comments.  Things like associating us with "herbal remedy whackos like so many others", and so forth.
