When we brought our Irish Terrier puppy home for the first time our friend said to get this book. It is simple and makes sense. If you follow their guidelines your dog will be housebroken in record time. The only accident our dog had since that time was 100 per cent OUR fault and not the dogs. I cannot recommend this book more highly. First time dog owner? Get this book. I have since given copies to friends who are first time dog owners.
