I have a Golden puppy and a 10yo Yorkie, they both are benefitting from the information in this book. The hardest part about making the changes has been the humans in my dogs life not understanding, or freaking out that I give my dogs raw chicken wings. My dogs are healthy, happy, and love every meal. I am so glad I found this book! I have said goodbye to the long nights plagued with diarrhea because my Golden couldn't stomached commercial dog food. My Yorkie hated every brand of commercial dog food we tried him on. Now both are eating well and sleeping well and no more diarrhea!
