Bingley has been on raw for about 4 months now.
We use NaturalInstinct, which i suppose is classed as a 'prepared' raw food. We used to do it ourselves, which worked out cheaper, but switched mainly because it is less complicated for the people who look after him when we work. They were always worrying about giving him other raw foods, but with NI they find it really easy and convenient. TBH I didn't really find 'preparing' my own food that much of a hassle, just a matter of taking a freezer bag out the freezer. NaturalInstinct is great though, I would really recommend it. It is more costly than doing it yourself, but Bingley loves it.
Before we moved to raw, Bingley had been on a couple of different kibbles. We had lots of issues in the toilet area, he had extremely soft stools almost continually, anal gland issues and bad wind. He suffered from itchy skin and terribly runny, teary eyes. All completely cleared up now. We switched hoping this might improve, and it has just been the best decision we ever made. I read up on BARF and raw feeding quite a bit before we switched, and just all round I am much happier with him being on raw. Now i've switched I wouldn't go back to kibble. The benefits have just been above and beyond what we expected.
