Fully half of training for someone new to dogs is training the owner. Like aquatics, the learning curve seems steep at first, but with some research & applying what is learned you'll find what works best for you & the individual dog. Also as with aquatics, dog training is an ever evolving and growing thing, both are a lifetime learning experience.
Thought I'd mention the parallels between dog topics on a fish forum & fish topics on a dog forum are amusing, anyone ever involved in both understands the tangents they can go off on, as well as some of the misinformation. This is certainly not due to lack of caring, or trying, just lack of long term exposure to the topic material. Folks involved with a particular species seem to be very caring about all living things, unfortunately not everything applies equally from humans on down to plants. This is often difficult to grasp, but when you do it's a huge aha moment.
