I would say this is not the best book I have read, however, if you are new to the whole house training thing, then I would recommend it as a good starting point. For someone who is already experienced it only serves to confirm what you have been doing right but does however offer some insightful tips and advice. However, the title is somewhat misleading as the book does go on to explain that no two dogs are the same, hence there is no guarantee that your dog will be fully housetrained within the 7 day period which is, in effect, an estimation/generalisation! That said, if you do follow the guidelines and stick to a strict regime your fury friend will inevitably catch on in no time at all. It just takes patience and persistence. Don't put pressure on yourself though and go at your and your dog's own pace. Remember, dogs are born followers and as their pack leader it is your responsiblity to lay down the ground rules and to be consistent in their training. That way, there is little room for failure. I have two puppies and would say it took about a month before they were fully housetrained. That said, even now at six months old I still stick to their routine like clockwork and always keep a close eye on them. This book will lay down the foundation for good house breaking.
