Okay, first I have to say there are a few reviews here you can completely disregard as nonsense. First, dogs of all ages can be on a raw diet. Age has nothing to do with it, but health concerns might. So always talk with your vet before switching, but be aware that not all vets are up-to-date on the benefits of a raw diet. Some still have an unwarranted aversion to raw chicken bones (it's COOKED bones that will splinter and choke a dog), and many vets sell dog food in their clinics, so have a conflict of interest.
Second, not ALL kibble (dry dog food) is bad for your dog. Yes, most of it is garbage, the equivalent of feeding your dog fast food every day, BUT . . . there are some wonderful dry dog food brands out there (Acana, Orijen, Taste of the Wild, just to name three). So just know that you have options if you or your dog simply don't go for raw.
Now, having said all that, raw is the best way to feed your dog if you have the time, inclination, and most important, a dog who enjoys it. Believe it or not, not all dogs like raw. Most do, but you might have that rare one who doesn't, and that's okay. Again, there are some really good premium dog foods out there, so know you have options.
And finally, my actual review of this book - it's GREAT! It's a wonderful primer on the basics of feeding a raw diet. It's not the only book on this subject in my library, but it is one of the most valuable and you absolutely cannot go wrong if you are new to BARF by buying this book. It will get you off to a great start and give you valuable information on feeding your dog the BARF way.
