If you've bought (or just read) a "Dummy" book before, you know what it's like.  Just like every Dummy book I've read, there's tons of info; some you'll use and some you won't, laid out in easy to read chapters.  As soon as I opened the book, I started learning some stuff that I didn't know before, such as how to decide what personality type a puppy has when you're trying to pick one from a litter.  There was also a lot of info about how to know which personality type would be best for you.  There's also the usual info about choosing a breed, which people don't usually seem to heed much (even though they should), chapters on illnesses, etc.  I keep it by the chair where I often read and just flip through it, reading as I go.  Both my dogs are old and I haven't dealt with puppies in many years, but I expect that I will be sometime in the not-too-distant future.  This book will be a big help.
