It has been a staple for decades, and anyone who has trained a half decent dog has read it.
Remember that your dog is not a robot and it does want to please you over anything else. Have patience and have fun.
Edit:Sorry for funky format I donno how I did it.
And
These two books have been around forever. I have heard on this sub that they are dated, but these books have trained a lot of dogs. Just remember a dog is a being with it's own mind. It will get upset, it will not want to train sometimes, IT IS NOT A ROBOT. If you want a real hunting dog be prepared to spend a lot more time than you think, but you form some weird bond with a dog like that.
I haven't read that one, though I've currently got Water Dog on the way because my girlfriend and I adopted a golden retreiver/chesapeake bay retriever mix from the pound yesterday and the book was recommended by my aunt and uncle who have two dogs, one lab, one bluetick coon hound, both very well trained. I'm going to see how that works. I was re-familiarizing myself with training techniques and read, actually on Ceasar Milan's website regarding crate training and properly associating inside and outside with peeing and pooping and it says not to use negative reinforcement, only positive enforcement.
