I've been doing a lot of online research for obedience training books and there's one called "Secrets to Dog Training" that i see all the time. Some look more legit than others but I generally see them on ads that look spammy, like Get Dog Training Aids. Normally I wouldn't buy something like that, but it's literally the only ebook I've encountered. It seems like it's widely used- so is it a total scam or do you think it might be a good resource? I'd like to hear from some ACTUAL people. Thanks a lot.
